Find a cubic function with the given zeros.
[tex]\sqrt{5}, - \sqrt{5} , -7[/tex]
f(x) = [tex]x^{3} - 7x^{2} - 5x - 35[/tex]
f(x) = [tex]x^{3} + 7x^{2} - 5x + 35[/tex]
f(x) = [tex]x^{3} + 7x^{2} - 5x - 35[/tex]
f(x) = [tex]x^{3} + 7x^{2} + 5x - 35[/tex]
Answers
Answer:
The third: f(x) = x³ + 7x² - 5x - 35Step-by-step explanation:
[tex]f(x)=(x-\sqrt5)(x+\sqrt5)(x+7)\\\\f(x)=(x^2+x\sqrt5-x\sqrt5-(\sqrt5)^2)(x+7)\\\\f(x)=(x^2-5)(x+7)\\\\f(x)=x^3+7x^2-5x-35[/tex]
Answer:
C. f(x) = x³ + 7x² - 5x - 35Step-by-step explanation:
Given zeros of cubic function:
√5, -√5 and -7The cubic function has standard form:
f(x) = ax³ + bx² + cx + dWithout multiplying lets find the value of a, b, c and d:
a = 1 as all the answer optionsSum of the roots
-b/a = √5 - √5 - 7 = -7, so b = 7Sum of the products of the roots (taken two at a time)
c/a = √5*(-√5) + √5*(-7) + (-√5)(-7) = - 5, so c = -5Product of the roots
- d/a = √5*(-√5)*(-7) = 35, so d = -35So the cubic function is:
f(x) = x³ + 7x² - 5x - 35Correct option is C
Dana bikes 10 miles in 50 minutes at this rate how far will she bike in 90 minutes
Answers
Answer:
18 miles
Step-by-step explanation:
the ratio is miles/minute
10/50=0.2
so no just multiply the amount of minute you want 0.2*90= 18 miles
Answer and Step-by-step explanation:
In an hour and a half, Dana would go 18 miles since she's going a mile at regular intervals, so if she's trekking for an additional forty minutes, she will bicycle 8 miles. This implies that you'd increase five minutes by 8 miles (recall it's a mile for every 5 minutes) and that would give you forty. At that point simply add that to the 50 minutes she's been cycling as of now.

Solve the equation. 5t^3 +40t^2 = -80t
Answers
Answer:
-5t2 + 40t - 3
Step-by-step explanation:
Step-1 : Multiply the coefficient of the first term by the constant 5 • 3 = 15
Step-2 : Find two factors of 15 whose sum equals the coefficient of the middle term, which is -40 .
-15 + -1 = -16
-5 + -3 = -8
-3 + -5 = -8
-1 + -15 = -16
1 + 15 = 16
3 + 5 = 8
5 + 3 = 8
15 + 1 = 16

12 - b = 12.5 b = ?
-0.1 = -10c c = ?
Answers
Answer:
a = -15, b = -.5, c = -1
Step-by-step explanation:
1/3a = -5 --> multiply each side with 3 --> a = -15
12 - b = 12.5 --> subtract 12 from both sides --> -b = .5 --> multiply each side with -1 to get b positive --> b = -.5
.1 = -10c --> multiply each side with -10 --> c = -1

what is the slope of the the line shown below?
Answers
Answer:
The answer is A. -2/7
Step-by-step explanation:
which equation represents the line that passes through the points (3,4) and (1,-2)
Answers
Answer:
y = 3x - 5
Step-by-step explanation:
First, you find the slope by finding the change in y and dividing that by the change in x of the two points.
-2 - 4 = -6, so -6 is the change in y.
1 - 3 = -2, so -2 is the change in x.
Then, since slope is change in y divided by change in x, you have -6/-2 = 3.
So far your equation is y = 3x + b and you're trying to find b to finish the equation.
To do this, you can pick one of the points and substitute the x and y values into the equation to find what value of b makes it true. Using (1, -2) we have
y = 3x + b --> -2 = 3(1) +b
-2 = 3 + b
b = -5
That means your equation is y = 3x - 5

How to solve this
3 = (2x + 8)/3
Answers
Answer:
x = 1/2
Step-by-step explanation:
First you want to get rid of the fraction, so you can multiply both sides of the equation by 3.
9 = 2x + 8
Then, subtract 8 from both sides to get x by itself.
1 = 2x
Finally, divide both sides by 2 so you only have one x
1/2 = x
This means that the answer is x = 1/2.
Answer:
x=1/2 or 0.5
Step-by-step explanation:
(2x+8)/3=3
(2x+8)=3x3
(2x+8)=9
2x=9-8
2x=1
x=1/2
x=0.5

Answers
Answer:
20 degrees
Step-by-step explanation:
The sum of angle on a straight line is 180 degrees
x+20 + 7x = 180
8x + 20 = 180
8x = 180 -20
8x = 160
x = 160/8
x = 20
Hence the value of x is 20 degrees
