Stealth Bank has deposits of $700 million. It holds reserves of $70 million and has purchased government bonds worth $215 million. The bank's loans have a market value of $490 million. What does Stealth Bank's net worth, or equity capital, equal?
Answer:
$75 million
Step-by-step explanation:
Given that:
Reserve value = $70 million
Purchased government bond = 215 million
Market value of loan = $490 million
Net worth :
Assets - liability
Assets = (Market value of loan + purchased government bond + reserve value)
(490 million + 215 million + 70 million)
275 million + 70 million
= $775 million
Liability = Deposits = $700 million
Net worth = ($775 - $700) million
Net worth = $75 million
What role do animals have in the carbon cycle?
Group of answer choices
use water and release oxygen
use sugar and release carbon
use carbon and release oxygen
use carbon and release nitrogen
Answer:
use sugar and release carbon
Step-by-step explanation:
Animals they eat and then release carbon through respiration. Nitrogen is only in the nitrogen cycle, and the only living organisms that can release oxygen are plants because humans and animals cannot photosynthesize. LOL!
a small airplane flies 1 015miles with an average speed of 290 mph. 1.75 hours after the plane leaves, a Boeing 747 leaves from the same point. Both planes arrive at the same time; what was the average speed of Boeing 747?
Answer:
The Boeing 747 had an average speed of 580 mph.
Step-by-step explanation:
Constant speed motion
An object is said to travel at constant speed if the ratio of the distance traveled by the time taken is constant.
Expressed in a simple equation, we have:
[tex]\displaystyle v=\frac{d}{t}[/tex]
Where
v = Speed of the object
d = Distance traveled
t = Time taken to travel d.
From the equation above, we can solve for d:
d = v . t
And we can also solve it for t:
[tex]\displaystyle t=\frac{d}{v}[/tex]
The small airplane travels 1015 miles at a constant speed of v=290 miles/hour. The time it took to arrive its destiny was:
[tex]\displaystyle t=\frac{1015}{290}[/tex]
t = 3.5 hours
The Boeing 747 left from the same point 1.75 hours after the small plane and traveled the same distance. It needed a time t' = 3.5 - 1.75 = 1.75 hours, thus its speed must have been:
[tex]\displaystyle v=\frac{1015}{1.75}=580[/tex]
The Boeing 747 had an average speed of 580 mph.

The process for rationalizing a denominator in a variable expression is the same as in a numeric expression. Here’s a real-world example. The kinetic energy of the car of a rollercoaster is given by the formula k = one-half m v squared where k is kinetic energy, m is the mass of the car, and v is the velocity of the car. Solving this formula for v, we get v = StartRoot StartFraction 2 k Over m EndFraction EndRoot Which formula gives the velocity of the car in simplest form?
Answer:
It's B
Step-by-step explanation:
Got it right on EDGE2020
The value of velocity of the car will be v = √(2km) / m. Then the correct option is B.
What is kinetic energy?If the object of mass m is moving with speed v. Then the kinetic energy of the object will be
KE = (1/2) mv²
The process for rationalizing a denominator in a variable expression is the same as in a numeric expression.
Here’s a real-world example.
The kinetic energy of the car of a rollercoaster is given by the formula
k = 1/2 m v²
Where k is kinetic energy, m is the mass of the car, and v is the velocity of the car.
Solving this formula for v, we get
[tex]\rm v = \sqrt{\dfrac{2k}{m}}[/tex]
Simplify the equation, we have
[tex]\rm v = \sqrt{\dfrac{2km}{m^2}}\\\rm v = \dfrac{\sqrt{2km}}{m}[/tex]
Then the correct option is B.

1. Matthew decided that he would like to spend his summer working and saving his money. He begins the summer with no money in his account, but he is getting paid $160.00 per week to mow lawns. His brother Dillon began the summer with $345.00 and has decided that he will referee soccer games. He will make $45.00 per week. After how many weeks will Matthew and Dillon have the same amount of money?
the anwer is no matthew will not have the same amount of money
Answer: 3 weeks.
Step-by-step explanation: Matthew's pay goes up by $160 a week, so that's y=160x.
Dillon's pay is $45 a week, but started out with $345. So, that's y=45x+345.
So, they will have the same amount of money after 3 weeks.

8) Eugene borrows $250 at a 4% annual interest rate. If he does not
make any payments, how much simple interest will he owe in 18 months?
A) $10
B) $15
C) $18
D) $20
Answer:
The simplest interest will be $15 ⇒ B
Step-by-step explanation:
The rule of the simple interest is I = Prt, where
P is the initial amountr is the rate in decimalt is the time∵ Eugene borrows $250 at a 4% annual interest rate
∴ P = 250
∴ r = 4% = 4 ÷ 100 = 0.04
∵ The time is 18 months
→ Change the time to year because the rate is annual
∵ 1 year = 12 months
∴ t = 18 ÷ 12 = 1.5 years
→ Substitute the values of P, r, and t in the rule above to find the interest
∵ I = 250 × 0.04 × 1.5
∴ I = 15
∴ The simplest interest will be $15
Suppose a,b,c represent three positive whole numbers. if a+b=13 and b+c=22 and a+c=19 what is the value of c
Answer: C = 14
Step-by-step explanation: You can assume the A is less than B, and if you just go down in numbers such as A=6 and B=7 (To solve A + B = 13), you will eventually get to A=5 and B=8. If you do B = 8 + C = 14 ( That you get after subtracting 8 by 22 ) You should get 22, and to proof check it, you do A + C which is going to be 5 + 14 and you get 19 thus proving that C = 14.

Occurs when f"(x) = 0 or undefinedPoints of Inflection (P.I) - Actual x-values when the graph f(x) changes concavityNumber Line Test - Helps us determine whether a P.P.I is a P.IStep-by-step explanation:
Step 1: Define
[tex]f(x)=\frac{3}{1+x^2}[/tex]
Step 2: Find 2nd Derivative
1st Derivative [Quotient/Chain/Basic]: [tex]f'(x)=\frac{0(1+x^2)-2x \cdot 3}{(1+x^2)^2}[/tex]Simplify 1st Derivative: [tex]f'(x)=\frac{-6x}{(1+x^2)^2}[/tex]2nd Derivative [Quotient/Chain/Basic]: [tex]f"(x)=\frac{-6(1+x^2)^2-2(1+x^2) \cdot 2x \cdot -6x}{((1+x^2)^2)^2}[/tex]Simplify 2nd Derivative: [tex]f"(x)=\frac{6(3x^2-1)}{(1+x^2)^3}[/tex]Step 3: Find P.P.I
Set f"(x) equal to zero: [tex]0=\frac{6(3x^2-1)}{(1+x^2)^3}[/tex]Case 1: f" is 0
Solve Numerator: [tex]0=6(3x^2-1)[/tex]Divide 6: [tex]0=3x^2-1[/tex]Add 1: [tex]1=3x^2[/tex]Divide 3: [tex]\frac{1}{3} =x^2[/tex]Square root: [tex]\pm \sqrt{\frac{1}{3}} =x[/tex]Simplify: [tex]\pm \frac{\sqrt{3}}{3} =x[/tex]Rewrite: [tex]x= \pm \frac{\sqrt{3}}{3}[/tex]Case 2: f" is undefined
Solve Denominator: [tex]0=(1+x^2)^3[/tex]Cube root: [tex]0=1+x^2[/tex]Subtract 1: [tex]-1=x^2[/tex]We don't go into imaginary numbers when dealing with the 2nd Derivative Test, so our P.P.I is [tex]x= \pm \frac{\sqrt{3}}{3}[/tex] (x ≈ ±0.57735).
Step 4: Number Line Test
See Attachment.
We plug in the test points into the 2nd Derivative and see if the P.P.I is a P.I.

Step 5: Identify
Since f"(x) changes concavity from positive to negative at [tex]x=\frac{-\sqrt{3}}{3}[/tex] and changes from negative to positive at [tex]x=\frac{\sqrt{3}}{3}[/tex], then we know that the P.P.I's [tex]x= \pm \frac{\sqrt{3}}{3}[/tex] are actually P.I's.
Let's find what actual point on f(x) when the concavity changes.
[tex]x=\frac{-\sqrt{3}}{3}[/tex]
Substitute in P.I into f(x): [tex]f(\frac{-\sqrt{3}}{3} )=\frac{3}{1+(\frac{-\sqrt{3} }{3} )^2}[/tex]Evaluate Exponents: [tex]f(\frac{-\sqrt{3}}{3} )=\frac{3}{1+\frac{1}{3} }[/tex]Add: [tex]f(\frac{-\sqrt{3}}{3} )=\frac{3}{\frac{4}{3} }[/tex]Divide: [tex]f(\frac{-\sqrt{3}}{3} )=\frac{9}{4}[/tex][tex]x=\frac{\sqrt{3}}{3}[/tex]
Substitute in P.I into f(x): [tex]f(\frac{\sqrt{3}}{3} )=\frac{3}{1+(\frac{\sqrt{3} }{3} )^2}[/tex]Evaluate Exponents: [tex]f(\frac{\sqrt{3}}{3} )=\frac{3}{1+\frac{1}{3} }[/tex]Add: [tex]f(\frac{\sqrt{3}}{3} )=\frac{3}{\frac{4}{3} }[/tex]Divide: [tex]f(\frac{\sqrt{3}}{3} )=\frac{9}{4}[/tex]Step 6: Define Intervals
We know that before f(x) reaches [tex]x=\frac{-\sqrt{3}}{3}[/tex], the graph is concave up. We used the 2nd Derivative Test to confirm this.
We know that after f(x) passes [tex]x=\frac{\sqrt{3}}{3}[/tex], the graph is concave up. We used the 2nd Derivative Test to confirm this.

We know that after f(x) passes [tex]x=\frac{-\sqrt{3}}{3}[/tex] , the graph is concave up until [tex]x=\frac{\sqrt{3}}{3}[/tex]. We used the 2nd Derivative Test to confirm this.

Is it possible to improve your grade from a "d" to a "b"?
Answer: Of course it is possible if you try your hardest and study
Answer:
Depends
Step-by-step explanation:
Hello! This problem really depends on where you are in the grading period and how many grades are entered in relation to your grade. If you have a D but only have 2 grades then getting a B in the class should be relatively easy. However, if you have a D in a class that you have 15 graded assignments in it will be much harder to raise your grade to a B. Best thing to do is work at this early and try not to let your grade dip throughout the grading semester.

A certain fraction has the value 3/4. If its numerator is decreased by 7 and its denominator is increase by 4, the resulting fraction has the value 1/2. Find the original fraction
Answer:
n = 16 - 7
n = 9
Step-by-step explanation:
If the numerator of a fraction is increased by 3, the fraction becomes 3/4."
Cross multiply
4(n+3) = 3d
4n + 12 = 3d
"If the denominator is decreased by 7, the fraction becomes 1."
Cross multiply
1n = d - 7
n = (d-7)
In the 1st equation replace n with d-7
4(d-7) + 12 = 3d
4d - 28 + 12 = 3d
4d - 3d - 16 = 0
d = 16 is the denominator
then n = 16 - 7
n = 9
9/16 = the original equation

Bryce had a $25 gift card to use on songs and games at an online media store. Songs cost $2 each and games cost $5 each. Bryce spent all the money on the gift card to download 8 items. Solve the system to determine how many games he purchased. Let s represent the number of songs and g represent the number of games. s + g = 8 2s + 5g = 25 Bryce purchased games.
Answer:
Bryce purchased 3 games.
Step-by-step explanation:
To find the number of songs and games that Bryce downloaded, we need to solve the following system of equations:
s + g = 8
2s + 5g = 25
We know that:
s + g = 8 → 2s + 2g = 16 → 2s = 16 -2g
2s + 5g = 25 → 16 - 2g + 5g = 25
→3g = 25 - 16
→3g = 9
→ g = 3
Therefore, bryce downloaded 3 games and 5 songs!
