Answer:

C.

Step-by-step explanation:

Simply add the two functions.

5x³+2x²-7x+4

+            3x-7

Everything with an exponent stays the same because there is nothing else with those exponents in the other function. So all you're doing is adding the -7x+4 and 3x -7.

-7x+3x = -4x

4 - 7 = -3

That leaves you with answer C:

5x³+2x²-4x-3

Answer:

[tex]C.(f+g)(x)=(5x^3+2x^2-4x-3)[/tex]

Step-by-step explanation:

[tex]We\ are\ given\ that,\\f(x)=5x^3+2x^2-7x+4\\g(x)=3x-7\\Hence,\\(f+g)(x)\\=f(x)+g(x)\\Hence,\\f(x)+g(x)=(5x^3+2x^2-7x+4)+(3x-7),\\ f(x)+g(x)=(5x^3+2x^2-7x+3x+4-7) \\f(x)+g(x)=(5x^3+2x^2-4x-3)\\Hence,\\(f+g)(x)=(5x^3+2x^2-4x-3)[/tex]

Answer:

the first one is correct

The equivalent algebraic expression to [tex]\sqrt[3]{200k^{15}}[/tex] is [tex]2~k^5~\sqrt[3]{25}[/tex]

The correct answer is an option (B)

"It is a mathematical statement which consists of numbers variables and some algebraic operations."

"It refers to the number of times a number is multiplied by itself."

For given question,

We have been given an algebraic expression [tex]\sqrt[3]{200k^{15}}[/tex]

We need to find an equivalent algebraic expression to given expression.

We know that the properties of exponents,

for positive integers a, b, n

[tex]\sqrt[n]{a}=a^{(\frac{1}{n} )}\\\\\sqrt[n]{ab}=a^{(\frac{1}{n} )}b^{(\frac{1}{n} )}[/tex]

We can write algebraic expression [tex]\sqrt[3]{200k^{15}}[/tex] as,

[tex]\sqrt[3]{200k^{15}}\\\\=\sqrt[3]{25\times 8\times k^{15}}\\\\=(25)^{\frac{1}{3} }\times (8)^{\frac{1}{3} }\times (k^{15})^{\frac{1}{3} }\\\\=\sqrt[3]{25}\times 2\times (k)^{\frac{15}{3} }\\\\ =2\sqrt[3]{25} \times k^5\\\\=2~k^5~\sqrt[3]{25}[/tex]

Therefore, the equivalent algebraic expression to [tex]\sqrt[3]{200k^{15}}[/tex] is [tex]2~k^5~\sqrt[3]{25}[/tex]

The correct answer is an option (B)

Answer:

the b is 20

Step-by-step explanation:

The computation of the b is shown below

Given that

y = mx + b

where

m = -2

x = 3

y = 14

Now placing these values to the above formula to determine the value of b

14 = -2(3) + b

14 = -6 + b

b = 14 + 6

= 20

Hence, the b is 20

We simply applied the above formula so that the correct value could come

Answer:

Sam has the more convincing victory with a greater Zscore value

Step-by-step explanation:

Given that :

Year 1:

Mean finish time (m) = 185.64

Standard deviation (s) = 0.314

Sam's time (x1) = 185.29

Year 2:

Mean finish time (m) = 110.3

Standard deviation (s) = 0.129

Rita's time (x1) = 110.02

Zscore = (x - mean) / standard deviation

Sam's Zscore :

(185.29 - 185.64) / 0.314

= - 0.35 / 0.314

= −1.114649

= - 1.115

Rita's Zscore :

(110.02 - 110.3) / 0.129

= - 0.28 / 0.129

= −2.170542

= - 2.171

Sam has the more convincing victory with a greater Zscore value

Answer: 500.7

500.75 = 500.7

Step-by-step explanation:

The estimated value is 500

Estimating in math is a way of approximately calculating an answer (getting a 'rough answer') or to check its accuracy (the 'right answer').

Given that, 9965 divided by 19.9 estimate

Let 9965 ≈ 9970

19.9 ≈ 20

9970 ÷ 20

9970 / 20

= 498.5

≈ 500

Hence, the estimated value is 500.
