Answer:

b < -7 or b > 7

Step-by-step explanation:

b is surrounded by absolute value bars, which means that whether the value of b is negative or positive, the bars will make it positive. |b| is said to be greater than 7, so the value of b must be:

less than -7 (it can be -8, -9, -10, ...) because the absolute value bars will make it positive.

&

greater than 7 (it can be 8, 9, 10) because it will stay positive anyway.

Therefore, the second answer choice is correct.

I hope this helped! :)

Suppose an astronaut can jump vertically with an initial velocity of 5 m/s. The time that it takes him to touch the ground is gi

Vitek1552 [10]

Answer:

$t=1.020s$

Step-by-step explanation:

Given Equation:

$5t-0.5at^{2} =0$

Actually the given equation is the 2nd equation of motion

i.e. $S =V_{i} t+0.5at^{2}$

where $S=0$ because the astronaut jumps on the earth

and initial velocity $V_{i}=5$

to find time $t$ , put the given value of $a=9.8m/s^{2}$ in the given equation, we get

$5t-0.5(9.8)t^{2} =0\\t(5-4.9t)=0\\ \ dividing\ both\ sides\ by\ t\ we \ get\\ 5-4.9t=0\\4.9t=5\\t=\frac{5}{4.9}\\ t=1.020s$

it will take $t=1.020s$ to reach the ground if he jumps on the Earth

Geometry math question no Guessing and Please show work thank you

Theorem

In a triangle, the measure of an exterior angle equals the sum of the measures of its two remote interior angles.

x + y = z

4n - 18 + n + 8 = 133 - 6n

5n - 10 = 133 - 6n

11n = 143

n = 13

z = 133 - 6n = 133 - 6(13) = 133 - 78 = 55

A complete graph of the polynomial function f is provided. Use your knowledge of the domain, range, behavior at each x intercept

Papessa [141]

The graph represents a polynomial graph, and the equation of the polynomial graph is f(x) = -(x + 5)³(x - 2)²

<h3>How to determine the equation?</h3>

From the graph, we have the following observations:

The graph has a turning point at x = 2
The graph changes the factor of its direction at x = -5

This means that the graph has a multiplicity of 2 at x = 2 and a multiplicity of 3 at x = -5

So, we have:

f(x) = a(x + 5)³(x - 2)²

The curve is inverted,

This means that a < 0

Assume a = -1.

Then, we have:

f(x) = -(x + 5)³(x - 2)²

Hence, the equation of the polynomial graph is f(x) = -(x + 5)³(x - 2)²
