What are the zeros of f(x)=x^3+2x^2-7x+4? Which statement is true regarding the behavior of the graph of f at each zero
Answer: (-4,0) , (1,0)
Step-by-step explanation:
I used this website called Desmos it could help with your questions like this.
Answer:
Step-by-step explanation:
f(x)=x³+2x²-7x+4
at x=1
f(1)=1³+2(1)²-7(1)+4=1+2-7+4=0
so x=1 is one zero.
1) 1 2 -7 4
| 1 3 -4
___________
1 3 -4 |0
x²+3x-4=0
x²+4x-x-4=0
x(x+4)-1(x+4)=0
(x+4)(x-1)=0
x=-4,1
zeros are -4,1,1
coefficient of leading term is +
so it starts from bottom on the left at ends up on the right.
There is a cusp at x=1
or it decreases on left of 1 and and increases on the right.
at x=-4 ,it increases.

Answer:
p = 7
Step-by-step explanation:
trust me
Answer:
p = 7
Step-by-step explanation:
Given value of q = 4 so,
5p - 11 = 6 × 4
=> 5p = 24 + 11
=> 5p = 35
[tex] = > p = \frac{35}{5} [/tex]
=> p = 7(Ans)

Kenya bought 4 boxes of
pencils for $3.99 each. She
also bought 2 boxes of
markers for $4.99 each. If
she paid the cashier with a
$50 bill, how much change
will Kenya get back?
Answer:
$24.06
Step-by-step explanation:
pencils: x
markers = m
y = total
y - (4x + 2m)
50 - (4*3.99 + 2*4.99)
50 - (15.96 + 9.98)
50 - 25.94
24.06
Answer:
24.94
Step-by-step explanation:
4 times 3.99 is 15.96
2 times 4.99 is 9.98
15.96 plus 9.98

Rashawn kept a record of how many hours he spent listening to music for 6 days during school vacation and displayed his results in the table below.
On Sunday, Rashawn listened to music for 12 hours. Should he use the mean or median to describe the data for the entire week?
Which statement explains whether the mean or median is the better measure of center?
A. The mean is the better measure because Rashawn listened to music the median number of hours on only 2 days of the week.
B. The mean is the better measure for the entire week because their is no outlier.
C. The median is the better measure because the mean is affected by the outlier.
D. The median is the better measure because almost all of the data points are between 6 and 7.
Answer:
B. The mean is the better measure for the entire week because their is no outlier.
Answer: C The median is the better measure because the mean is affected by the outlier

Kiki's mother cooked a dinner that contained a total of 992 calories. She also prepared a dessert that contained a total of 846 calories. The dinner was divided into 4 equal servings. The dessert was divided into 6 equal
servings. Kiki had one serving of dinner and one serving of dessert.
Which equation could be used to solve for n, the number of calories that kiki
ate?
A. n = 992 x 4 + 846 x 6
B. n = 1,838 / 10
C. n = 992 / 4 + 846 / 6
D. n = 992 / 4 - 846 / 6
Answer: C
Step-by-step explanation:
992/4=165
846/6=141
165+141=306
(992/4) + (846/6) = 306 total calories consumed

What is the angle of F?
R 134 degrees
L 68 degrees
Answer:
angleF=66
Step-by-step explanation:
F+L=R
F+68=134
F=134-68=66
or
360-68-(180-R)=66
hat is the surface area of a cylinder that has a volume if 785.4in3 and a radius of 5 in?
A 471.2in2
B 10in2
C 150in2
D 4712.3in2
Answer:
A. 471.2 in²Step-by-step explanation:
Cylinder volume:
V = πr²hCylinder surface area:
A = 2πr(r + h)Find h from the first equation:
h = V/(πr²) = 785.4/(3.14*5²) = 10 inFind surface area:
A = 2π(5)(5 + 10) = 471.23 in²Correct choice is A
Answer:
volume of cylinder=πr²h
785.4=22/7×5²×h
h=785.4×7/(22×25)=9.99=10in
Step-by-step explanation:
surface area of cylinder =2πr(r+h)=2π×5(5+10)=
471.238898038in²
A 471.2in2 is your answer.

What is the EDGE LENGTH of a cube with VOLUME 27/64 cubic units?
Answer:
The edge length is 3/4
Step-by-step explanation:
Given
Shape: Cube
[tex]Volume = 27/64[/tex]
Required
Determine the edge length
Let the edge length be l.
So:
[tex]Volume=l^3[/tex]
Substitute 27/64 for Volume
[tex]27/64=l^3[/tex]
Express as exponent og 3
[tex]3^3/4^3 = l^3[/tex]
Apply indices rule
[tex](3/4)^3 = l^3[/tex]
Take cube root of both sides
[tex]3/4 = l[/tex]
[tex]l =3/4[/tex]
Answer:
3/4
Step-by-step explanation: try dividing because 4 is able to reach 64 and 3 can go to 27

slope point -
through:(3,-1) and (-1,-4)
Answer:
m = 3/4 or 0.75Step-by-step explanation:
Use slope formula:
m = (y₂ - y₁)/(x₂ - x₁)Substitute values of coordinates:
m = (-4 - (-1))/(-1 - 3) = -3/-4 = 3/4 or 0.75Slope
m=(-4+1)/(-1-3)m=-3/-4m=3/4Solve for x. Enter the solutions from least to greatest.

Four more than the product of 2 and a
Four more than the product of 2 and a:
4+2a
Answer:
2a + 4
Step-by-step explanation:
The key word, "product," means you're multiplying, and since it says the "product of 2 and a," you're multiplying 2 and a. To simplify that, you can write 2a (which is equal to 2 · a).
Since it says four more (key word is more), you need to add four to 2a. Since if you have "less than" or "more than", the product will be before the number we're adding, leaving you with 2a + 4.
