How do I graph f(x) = -x^2 +2x -4
2+2(-3)^2
Plz answer :) with steps
Answer:
-16
Step-by-step explanation:
2 + 2(-3)²
Exponents come first, so we would multiply -3 by itself.
2 + 2(-9)
Next is Multiplication, so we multiply 2 and -9 together
2 - 18
We subtract 18 from 2 to get,
-16
I hope that this helps! :)

The product of two consecutive integers is 420. Which quadratic equation can be used to find x, the lesser number? x2 + 1 = 420 x2 + 2 = 420 x2 + x = 420 x2 + 2x = 420
Answer:Answer:
The answer is x^2 + x =420
Step-by-step explanation:
It is given that
The product of two consecutive integers is 420
Le x be the first number, then
second number is the next consecutive number of x which is (x +1)
The product of these numbers can be written as
x (x + 1) which is equal to 420
x (x + 1) = 420
x^2 + x = 420
So the quadratic equation is
x^2 + x = 420

1. A multi-cab starter motor has a current of 60.0 A and a voltage of 12 V. What is
the resistance of the starter motor?
А
Given: Current (1)
Voltage (V)
Required: Resistance (9)
V
Formula:
R= voltage
curent
Solution:
V - IR
Answer:
Resistance -
92, the resistance of the electric motor.
Answer: 0.20 Ω
Step-by-step explanation:
From the question, we are informed that a multi-cab starter motor has a current of 60.0 A and a voltage of 12 V. The resistance of the starter motor will be calculated thus:
Current (I) = 60.0A
Voltage (V) = 12V
Resistance = Unknown
Since Voltage = Current × Resistance
Therefore, Resistance = Voltage / Current
= 12/60
= 0.20 Ω
The resistance of the motor is 0.20 Ω
The resistance of the starter motor if a multi-cab starter motor has a current of 60.0 A and a voltage of 12V is 0.2 ohms
Based on the given question, for us to get the resistance of the starter motor, we will need to use Ohm's law.
According to the law, the current I passing through a conductor at constant temperature is directly proportional to the voltage "V". Mathematically;
V = IR
V is the voltage = 12V
I is the current = 60.0A
R is the resistance
Substitute the given parameters into the formula as shown:
12 = 60 R
R = 12/60
R = 1/5
R = 0/2
Hence the resistance of the starter motor if a multi-cab starter motor has a current of 60.0 A and a voltage of 12V is 0.2 ohms

12) If tan A=5/12 . find the value of (sin A + COS A) sec A.
Answer:
(sin(A) + cos(A)).sec(A) = 17/12
Step-by-step explanation:
tan(A) = 5/12
sin(A) = 5/13
cos(A) = 12/13
sec(A) = 1/(cos(A)) = 13/12
(sin(A) + cos(A)).sec(A) = (5/13 + 12/13).13/12
= 17/13.13/12
= 17/12

Answer:
16x-4x +48x +88xStep-by-step explanation:
Like terms are ones with the same variable (or set of variables). Here, any x-terms are "like" terms. They are combined by adding their coefficients.
4x +4x +4x +4x = x(4+4+4+4) = 16x
-7x +4 +3x = x(-7+3) +4 = -4x +4
3x +5x +8 = x(3+5) +8 = 8x +8
4x +4x = x(4+4) = 8x

There are 600 performers in a dance recital. The ratio of men to women is 4:6. How many men performers were in the dance recital
Answer: 240 men
Step-by-step explanation:
From the question, we are informed that there were 600 performers in a dance recital and that the ratio of men to women is 4:6.
Fraction of men at the recital = 4/10
Fraction of women at the recital = 6/10
The number of men performers that were in the dance recital will be:
= 4/10 × 600
= 240 men
There were 240 men at the recital.
Given the quadrant of theta in standard position and a trigonometric function value of theta , find the exact value for the indicated function. I, cos theta = 0.25; tan theta
Answer:
[tex]\sqrt{15}[/tex]
Step-by-step explanation:
[tex]\cos(\theta)=\frac{1}{4}[/tex] is given.
My attempt will to be to use the Pythagorean Identity:
[tex]\cos^2(\theta)+\sin^2(\theta)=1[/tex]
[tex](\frac{1}{4})^2+\sin^2(\theta)=1[/tex]
[tex]\frac{1}{16}+\sin^2(\theta)=1[/tex]
Subtract 1/16 on both sides:
[tex]\sin^2(\theta)=\frac{15}{16}[/tex]
We have the following quotient identity:
[tex]\frac{\sin^2(\theta)}{\cos^2(\theta)}=\tan^2(\theta)[/tex]
[tex]\frac{\sin^2(\theta)}{\cos^2(\theta)}=\frac{\frac{15}{16}}{\frac{1}{16}}[/tex]
Multiply the numerator and denominator by 16. This is multiplying the fraction by 1 so this doesn't change the value of the fraction.
[tex]\tan^2(\theta)=\frac{15}{1}[/tex]
[tex]\tan^2(\theta)=15[/tex]
Square root both sides:
[tex]\tan(\theta)=\pm \sqrt{15}[/tex]
Since we are in the first quadrant then all 6 trigonometric functions are positive there so the answer is [tex]\sqrt{15}[/tex].

Michelle is having a poster printed from a picture that is 4 inches wide by 6 inches tall. The enlarged poster is 20 inches wide and 30 inches tall. Which proportion can be used to represent the picture sizes?
StartFraction 6 over 4 EndFraction = StartFraction 20 over 30 EndFraction
StartFraction 4 over 6 EndFraction = StartFraction 20 over 30 EndFraction
StartFraction 4 over 6 EndFraction = StartFraction 30 over 20 EndFraction
StartFraction 4 over 30 EndFraction = StartFraction 6 over 20 EndFraction
Answer:
The correct answer is:
Option 2: [tex]\frac{4}{6} = \frac{20}{30}[/tex]
Step-by-step explanation:
Given that
Width of picture = 4 inches
Length of picture = 6 inches
Now
Width of poster = 20 inches
Length of poster = 30 inches
The proportion of the picture will be:
[tex]\frac{width}{length} = \frac{4}{6}[/tex]
Similarly the proportion of poster can be written as:
[tex]\frac{width}{length} = \frac{20}{30}[/tex]
Both proportions when combined can be written as:
[tex]\frac{4}{6} = \frac{20}{30}[/tex]
Hence,
The correct answer is:
Option 2: [tex]\frac{4}{6} = \frac{20}{30}[/tex]
Answer:
B
Step-by-step explanation:
This is becuase 30 and 6 are both the inches in height so their units must line up same goes with 4 and 20 becuase they are the same unit they must line up accordingly in the equation.

If you get 2 imaginary answers when using the quadratic formula, how does this relate to how many times (0, 1 or 2) a quadratic graph touches/crosses the x-axis?
Answer:Roots of a number indicates value where function will be zero. If an equation let's say
y = f(x) = x^2 -3x + 2 has two roots x = 1 and x =2 . Now if you will draw the graph, line will cross x-axis at 1 and 2 indicating y will become zero at 1 and 2. But if any equation has imaginary roots implies y will be never be zero for any real value of x and as we do not show imaginary number on a Cartesian plane we cannot make y =0 hence graph will never touch x-axis.

It should look like this:
Prefer colorful decorations Prefer neutral decorations
Pay attention 20 25
to fashion
Do not pay
attention to 72 33
fashion
Step-by-step explanation:
33 is 22% of 150. In the question it states that 70% of people do not pay attention to fashion. We need to find the other 48% here. In order to do that we multiply .48 by 150. That gets us 72. To check that answer you can add both 72 and 33 and then divide by 150, which gets 70%.
To get the amount of people that prefer neutral decorations and pay attention to fashion we need to add up 20 + 72 + 33 and that equals 125. Next, we take 150 and minus 125 of it to get 25.
Hope this helps!!

Find x. My teacher gave me what x equals but I don’t know the step-by-step explanations. x=6
Step-by-step explanation:
The triangle is isosceles, so the base angles are the same.
All three angles add up to 180°.
(6x + 4) + (6x + 4) + (18x − 8) = 180
30x = 180
x = 6
Answer:x=6
Step-by-step explanation:since those two sides shown are the same length, the missing angle is also 6x+4. the angles on a triangle always will equal 180. so you set the problem up as 6x+4+6x+4+18x-8=180. when you combine like terms it is then 30x=180. x=6
