Write the simplest polynomial function for each set of zeros
Zeros = -2, 5, -1
Answer:
the answer should be y = x^3 - 2x^2 - 13x - 10
Step-by-step explanation:
x = -2 5 -1
x + 2 = 0
x - 5 = 0
x + 1 = 0
f(x) = (x + 2) (x + 1)
x(x) + 2(x) + x(1) + 2(1)
x^2 + 2x + x + 2
x^2 + 3x + 2
f(x) = (x^2 + 3x + 2) ( x - 5)
x^2(x) + 3x(x) + 2(x) + x^2(- 5) + 3x(- 5) + 2(- 5)
x^3 + 3x^2 + 2x - 5x^2 - 15x - 10
x^3 - 2x^2 - 13x - 10
f(x) = x^3 - 2x^2 - 13x - 10

Find the length of AC.
a. 10.1
b. 10.0
c. 10.9
d. 8.86
PLEASE HELPPP ASAP
Answer:
Option D
Step-by-step explanation:
According to law of cosines =
[tex] {a}^{2} = {b}^{2} + {c}^{2} - 2bc. \cos(A) [/tex]
where 'a' is the uknown side , 'b' & 'c' are the given sides and angleA is the angle opposite to the uknown side i.e. opposite to 'a'.
Using the Law of cosines , we'll find the length of AC .
[tex] {ac}^{2} = {7}^{2} + {13}^{2} - 2 \times 7 \times 13 \times \cos(50) [/tex]
[tex] = > {ac}^{2} = 49 + 169 - 182 \times 0.76[/tex]
[tex] = > {ac}^{2} = 218 - 138.8 = 79.68[/tex]
[tex] = > ac = \sqrt{79.68} = 8.92 = 9(appx)[/tex]
In option D , if we'll round of 8.86 , then its appx 9. So option D is right

Clancy has 423 cups of yogurt to share with his friends at a party. Each guest will receive 1 serving of yogurt which is 34 of a cup. How many people can Clancy invite to his party if he needs a serving of yogurt as well?
Answer:
564 people
Step-by-step explanation:
Total cups of yogurt to share = 423 cups
Each guests get = 3/4 of a cup per serving
How many people can Clancy invite to his party if he needs a serving of yogurt as well?
Number of people Clancy can invite to his party = Total cups of yogurt to share / servings per guests
= 423 cups ÷ 3/4 cups
= 423 × 4/3
= 141 × 4
= 564
Number of people Clancy can invite to his party = 564 people
When the U.S. government needed 10,000 rifles for the army, Eli Whitney applied for the contract. He took several guns, dismantled them, put the pieces in a box, and shook it. He then randomly selected the pieces he needed, assembled on rifle, and fired it. What did he demonstrate
Answer:
interchangeable parts.
Step-by-step explanation:
Eli Whitney here demonstrates interchangeable parts.He took several guns, dismantled them, put the pieces in a box, and shook it. He then randomly selected the pieces he needed, assembled on rifle, and fired it. popularized in America when Eli Whitney used them to assemble muskets in the first years of the 19th century, allowed comparatively unskilled workers to manufacture vast quantities of arms rapidly and at lower expense, and made repair and replacement of parts exponentially simpler.

(a) Write the expression in expanded form. log(7x^3/z)
(b) Write the expanded form as a simplified single log. 3log(5) + 2log(x) – log(25)
Step-by-step explanation:
log(7x³/z) = log(7) + log(x³) - log(z).
3log(5) + 2log(x) - log(25) = log(125) + log(x²) - log(25) = log(125x²/25) = log(5x²).

Answer:
Option (5)
Step-by-step explanation:
f(x) is a function with the degree of 3, having zeros as x = 2, 2t, -2t
And f(1) = -15
Option (1)
f(x) = 2x³- 2x² + 2x - 30
f(1) = 2(1)³ - 2(1)² + 2(1) - 30
= 2 - 2 + 2 - 30
= -28 ≠ -15
Therefore, Option (1) is not the answer.
Option (2)
f(x) = 2x³ + 2x² + 2x - 30
f(1) = 2(1)³ + 2(1)² + 2(1) - 30
= 2 + 2 + 2 - 30
= 6 - 30
= -24 ≠ -15
Therefore, Option (2) is not the answer.
Option (3)
f(x) = 3x³ - 6x² + 12x - 12
f(1) = 3(1)³ - 6(1)² + 12(1) - 12
= 3 - 6
= -3 ≠ -15
Therefore, Option (3) is not the answer.
Option(4)
f(x) = 48x³- 9x² + 12x - 24
f(1) = 48(1)³ - 9(1)² + 12(1) - 24
= 48 - 9 + 12 - 24
= 27 ≠ -15
Therefore, Option (4) is not the answer.
Option (5)
f(x) = 3x³- 6x² + 12x - 24
f(1) = 3(1)³- 6(1)² + 12(1) - 24
= 3 - 6 + 12 - 24
= -15
Therefore, Option (5) is the correct option.
-write each product using an exponent 6 x 6 =
The product is expressed as an exponent as 6 x 6 = 6².
Given data:
To write the product 6 x 6 using an exponent, we can express it as 6².
The different Laws of exponents are:
mᵃ×mᵇ = mᵃ⁺ᵇ
mᵃ / mᵇ = mᵃ⁻ᵇ
( mᵃ )ᵇ = mᵃᵇ
mᵃ / nᵃ = ( m / n )ᵃ
m⁰ = 1
m⁻ᵃ = ( 1 / mᵃ )
When we multiply a number by itself, we can represent the repeated multiplication using an exponent. In this case, we have 6 multiplied by 6, which is the same as saying 6 raised to the power of 2 (6²).
The exponent 2 indicates that we are multiplying 6 by itself 2 times.
Hence, the product 6 x 6 can be written as 6².

Mae Ling earns a weekly salary of $390 plus a 8.0% commission on sales at a gift shop. How much would she make in a work week if she sold $4,300 worth of merchandise?
Answer:
She would make $734 in a work week if she sold $4,300 worth of merchandise.
Step-by-step explanation:
First, you should calculate the amount she would receive on comissions by multiplying the amount she sold for 8%:
$4,300*8%=$344
Now, you have to add the weekly salary plus the amount she receives for the comission on sales:
$390+$344=$734
According to this, the answer is that she would make $734 in a work week if she sold $4,300 worth of merchandise.
A juggler tosses a ball into the air. The balls height, h, and the t seconds can be represented by the equation h(t)=16t^2+40t+4. Suppose the juggler missed and the ball hit the ground. Find the maximum height of the ball and the time it took the ball to reach the ground. Round all answers to the nearest hundredth
Answer:
h= -20
t = -0.104 and -2.39s
Step-by-step explanation:
A juggler tosses a ball into the air. The balls height, h, and the t seconds can be represented by the equation h(t)=16t^2+40t+4. Suppose the juggler missed and the ball hit the ground. Find the maximum height of the ball and the time it took the ball to reach the ground. Round all answers to the nearest hundredth
The velocity of the body at its maximum height is zero
V= dh/dt
dh/dt = 32t + 40
0 = 32t+40
-32t = 40
t = 40/-32
t = -1.25s
Substitute t = -1.25 into the expression
h(t)=16t^2+40t+4.
h(-1.25)=16(-1.25)^2+40(-1.25)t+4.
h = 16(1.5625)-50+5
h = 25-45
h =-20
Hence the maximums height is -20m
The ball will reach the ground at h = 0
Substitute
h(t)=16t^2+40t+4.
0 = 16t^2+40t+4
Divide through by 4
0 = 4t²+10t+1
Factorize
-10±√10²-4(4)/2(4)
t = -10±√100-16/8
t = -10±√84/8
t =-10+9.17/8
t = -0.83/8 and -19.17/8
t = -0.104 and -2.39s

A triangle has side lengths of (9.8f-8.4)(9.8f−8.4) centimeters, (2.2f+4.9)(2.2f+4.9) centimeters, and (9.8g+9.2)(9.8g+9.2) centimeters. Which expression represents the perimeter, in centimeters, of the triangle?
Answer:
12f + 9.8g + 5.7 centimeters
Step-by-step explanation:
Side A = (9.8f-8.4) centimeters
Side B = (2.2f+4.9) centimeters
Side C = (9.8g+9.2) centimeters.
Perimeter of a triangle = Side A + Side B + Side C
= (9.8f-8.4) + (2.2f+4.9) + (9.8g+9.2)
= 9.8f - 8.4 + 2.2f + 4.9 + 9.8g + 9.2
Collect like terms
= 9.8f + 2.2f + 9.8g - 8.4 + 4.9 + 9.2
= 12f + 9.8g + 5.7 centimeters
Therefore, the expression which represents the perimeter of the triangle 12f + 9.8g + 5.7 centimeters
