Answer:

D. $10x^7 + 7x^5 -2x + 9$

Step-by-step explanation:

Like terms: $7x^7$ and $3x^7$ = $10x^7$

$5x^5$ and $2x^5$ = $7x^5$

$-3x$ and $x\\$ = $-2x$

$7$ and $2$ = $9$

The answer would be: $10x^7 + 7x^5 - 2x + 9$

Therefore, it is <u>option D</u>

Fofino [41]

The question is an illustration of related rates.

The rate of change between you and the ball is 0.01 rad per second

I added an attachment to illustrate the given parameters.

The representations on the attachment are:

$\mathbf{x = 100\ m}$

$\mathbf{\frac{dy}{dt} = 2\ ms^{-1}}$ ---- the rate

$\mathbf{\theta = \frac{\pi}{4}}$

First, we calculate the vertical distance (y) using tangent ratio

$\mathbf{\tan(\theta) = \frac{y}{x}}$

Substitute 100 for x

$\mathbf{y = 100\tan(\theta) }$

$\mathbf{\tan(\theta) = \frac{y}{100}}$

Differentiate both sides with respect to time (t)

$\mathbf{ \sec^2(\theta) \cdot \frac{d\theta}{dt} = \frac{1}{100} \cdot \frac{dy}{dt}}$

Substitute values for the rates and $\mathbf{\theta }$

$\mathbf{ \sec^2(\pi/4) \cdot \frac{d\theta}{dt} = \frac{1}{100} \cdot 2}$

This gives

$\mathbf{ (\sqrt 2)^2 \cdot \frac{d\theta}{dt} = \frac{1}{100} \cdot 2}$

$\mathbf{ 2 \cdot \frac{d\theta}{dt} = \frac{1}{100} \cdot 2}$

Divide both sides by 2

$\mathbf{ \frac{d\theta}{dt} = \frac{1}{100} }$

$\mathbf{ \frac{d\theta}{dt} = 0.01 }$

Hence, the rate of change between you and the ball is 0.01 rad per second

A paper air plane looking polygon with sides of 5 5 and 8 what is the area

VARVARA [1.3K]

If it has 3 sides then it's a triangle.
Using the formula $A= \sqrt{s(s-a)(s-b)(s-c)}$
where $s= \frac{a+b+c}{2}$
and a=5 b=5 c=8

∴ $s= \frac{5+5+8}{2} =9$
$area= \sqrt{9(9-5)(9-5)(9-8)}$
$area= \sqrt{144} = 12units^{2}$

How many solutions does 6d+8=14+3d have?

Stells [14]

Answer:

d =2

Step-by-step explanation:

6d+8=14+3d

Subtract 3d from each side

6d-3d+8=14+3d-3d

3d +8 = 14

Subtract 8 from each side

3d +8-8 = 14-8

3d =6

Divide by 3

3d/3 = 6/3

d =2
