Answer:

The equivalent expression is $2x^5+11x^3-5x^2$

Step-by-step explanation:

Given: $(2x^5+7x^3)-(5x^2-4x^3)$

Here we have expression and to simplify it

$\Rightarrow (2x^5+7x^3)-(5x^2-4x^3)$

Distribute minus sign

$\Rightarrow 2x^5+7x^3-5x^2+4x^3$

Combine the like terms (whose variable part same)

$\Rightarrow 2x^5+(7x^3+4x^3)-5x^2$

$\Rightarrow 2x^5+11x^3-5x^2$

Equivalent expression $\Rightarrow 2x^5+11x^3-5x^2$

Hence, The equivalent expression is $2x^5+11x^3-5x^2$

A cannonball is shot straight up into the air. The height of the cannonball at time t is represented by the function f(t)=−16t^2

san4es73 [151]

Answer:

the initial height

Step-by-step explanation:

given the height is represented by the function

f(t) = - 16t² + 40t + 3

Then the initial height is when t = 0, that is

f(0) = 0 + 0 + 3 = 3 ← initial height

Two people are standing on opposite sides of a hill. Person A makes an angle of elevation of 65° with the top of the hill and pe

Artyom0805 [142]

The rest of the question is as following
What is the distance from person B to the top of the hill?
===================================================
Answer;
The attached figure represents the explanation of the problem.
So, it is required to find the distance BH
It will be calculated as following
∠A = 65° and ∠B = 80°
∴ ∠H = 180° - (65° + 80° ) = 35°
But the side AB = 45
So, we can use the sine rule to find the side BH
$\frac{AB}{sin \ H} = \frac{BH}{sin \ A}$
$BH = \frac{sin \ A}{sin \ H} * AB$
$BH = \frac{sin \ 65}{sin \ 35} * 45$

∴ BH ≈ 71.1 feet

∴ The distance from person B to the top of the hill ≈ 71.1 feet
