Answer: (x-3)(2x+1)(8)
Step-by-step explanation: First factor out the 8 to get (8)(2x^2-5x-3). So now we have what number multiply out to -6 (ab) and add up to -5. -2 and -3 work out so we manipulate the equation like (8)(2x²-2x-3x-3). Factor out 2x in the first term and -3 in the second and keep going.
What is the Area of the compound shape below? *
Answer:
22m²
Step-by-step explanation:
2 wide, 9 height is 18 for the rectangle figure. We see that the rectangle figure has a width of 2 while the entire width is 4. So 4-2 means the width of the right triangle that's split off is 2.
We see the rectangle height is 5, and total figure is 9, so 9-5 = height of 4 for the triangle.
4x2 x 1/2(since its a triangle) = 4
4+18 = 22
Emily has 7 photos on one page of an album. She has 3 photos on each of the other 9 pages. How man photos are in Emily's album? *

Determine the niinimum and maximum value of the following trigonometric
function.
f(x) = 5 cos 3x – 3
9514 1404 393
Answer:
maximum: +2
minimum: -8
Step-by-step explanation:
The cosine has a minimum of -1 and a maximum of +1. Then the extremes of f(x) are ...
5(±1) -3 = -3±5 = +2, -8
The maximum of f(x) is +2; the minimum is -8.
Solve: 2y - 4 = 14
Please answer I put the points up please answer quik
Answer:hope it helps
Step-by-step explanation:
Simplifying
2y + -4 = 14
Reorder the terms:
-4 + 2y = 14
Solving
-4 + 2y = 14
Solving for variable 'y'.
Move all terms containing y to the left, all other terms to the right.
Add '4' to each side of the equation.
-4 + 4 + 2y = 14 + 4
Combine like terms: -4 + 4 = 0
0 + 2y = 14 + 4
2y = 14 + 4
Combine like terms: 14 + 4 = 18
2y = 18
Divide each side by '2'.
y = 9
Simplifying
y = 9
The solution to the equation 2y - 4 = 14 is y = 9.
We have,
To solve the equation 2y - 4 = 14, we can isolate the variable y by performing the necessary operations:
First, we add 4 to both sides of the equation to eliminate the -4:
2y - 4 + 4 = 14 + 4
Simplifying, we have:
2y = 18
Next, we divide both sides of the equation by 2 to isolate y:
2y/2 = 18/2
Simplifying further:
y = 9
Therefore,
The solution to the equation 2y - 4 = 14 is y = 9.

Answer:
.7
Step-by-step explanation:
I'm going to assume you meant to write all that stuff once
The conditional probability formula is as follows : (B|A)=(A∩B)/A
We're told that the two probabliites are independent of each other which means that A∩B= A*B
Which means we have
(.31*.7)/(.31)
This should simplify to .7
*note* a shortcut you can use when finding the conditional probability of two independent probabilities you can just take the first probability (or in this case B) and that'll be your final answer
What is the solutions set of y=x^2+2x+7and y=x+7
Answer:
when x=0 ,y=7
when x=-1, y=6
Step-by-step explanation:
Taking [tex]y=x^{2} +2x+7, y=x+7[/tex] as equation 1 and 2 respectively
Inserting equation 2 in 1,
[tex]x+7=x^{2} +2x+7\\[/tex]
getting rid of 7 since its in both the sides with the same + signs,
[tex]x^{2} +2x-x=0\\x^{2} +x=0\\x(x+1)=0\\x=0 / x=-1[/tex]
when x=0 ,
y=7
when x=-1 , y=6

Find the volume of the cylinder. Round to the nearest tenth
5 ft
2 ft
Given:
Radius of the cylinder = 2 ft
Height of the cylinder = 5 ft
To find:
The volume of the cylinder.
Solution:
Volume of a cylinder is:
[tex]V=\pi r^2h[/tex]
Where, r is the radius and h is the height of the cylinder.
Putting [tex]\pi = 3.14,r=2,h=5[/tex] in the above formula we get the volume of the given cylinder is:
[tex]V=(3.14)(2)^2(5)[/tex]
[tex]V=(3.14)(4)(5)[/tex]
[tex]V=62.8[/tex]
Therefore, the volume of the given cylinder is 62.8 ft².

An object is moving at a speed of 2 centimeters every 7 seconds. Express this speed in meters per week. Round your answer to the nearest whole number.
Answer:
v = 12121 m per week.
Step-by-step explanation:
Given that,
The object is moving at a speed of 2 centimeters every 7 seconds.
We need to find the speed in m per week.
2 cm = 0.02 m
1 week = 604800 s
7 s = [tex]1.65\times 10^{-6}\ week[/tex]
Speed = distance/time
So,
[tex]v=\dfrac{0.02\ m}{1.65\times 10^{-6}\ week}\\\\v=12121.21\ m/week \\\\or\\\\v=12121\ m/week[/tex]
So, the speed of the object is 12121 m per week.
Answer:
1728 meters per week, the answer of 1212 was wrong on my test.

Step-by-step explanation:
a.)
Equation for compound interest:

Cos? Tan? Sin? What is angle V?
Answer:
60degrees
Step-by-step explanation:
SInce our reference angle is <V;
Opposite = WU = 7√3
Hypotenuse= WV = 14
Using the SOH CAH TOA identity
son m<V = opposite/hypotenuse
sin m<V = 7√3/14
sin m<V = √3/2
m<V = arcsin(√3/2)
m<V = 60degrees
Hence the measure of angle V is 60degrees

Which equations represent exponential growth?
Which equations represent exponential decay?
Drag the choices into the boxes to complete the table.
Exponential Growth Exponential Decay
Answer:
Growth;
A = 20,000(1.08)^t
A = 40(3)^t
P = 1700(1.07)^t
Decay;
A = 80(1/2)^t
A = 1600(0.8)^t
P = 1700(0.93)^t
Step-by-step explanation:
The key to differentiate between decay and growth is the term inside the bracket
For growth, the term inside the bracket is greater than 1, while for decay, the term inside the bracket is less than 1
Looking at the given equations, we have;
Growth;
A = 20,000(1.08)^t
A = 40(3)^t
P = 1700(1.07)^t
Decay;
A = 80(1/2)^t
A = 1600(0.8)^t
P = 1700(0.93)^t
