Answer: D

Step-by-step explanation:

The slopes of two perpendicular lines are negative reciprocals of each other

The slope of this line is -1/4, the reciprocal is just the flipped fraction which is -4/1 or 4. Since it is a negative reciprocal you multiply it by -1. 2 negatives multiplied equals a positive so the slope of the perpendicular line is 4

D.4

y=mx + c ....(1)general line eqn)

y=-(1/4x) - 9 .....(2)


Comparing (1) and (2)

m=-1/4

Since both lines are

perpendicular

M=-1/m

Where M=gradient of other line

M=-1/(-1/4)

= -1 x - 4/1

=4
Therefore the gradient of the

other line is 4

What is the diameter of a sphere with a volume of 498 in3, to the nearest tenth of an inch
Romashka-Z-Leto [24]

Answer:

9.8 inches

Step-by-step explanation:

<h3>Formula for volume of the sphere is = 4/3πr³</h3><h3>Form and solve the equation for the radius</h3><h3>So: 4/3πr³= 498in³</h3><h3>πr³= 498in³*3/4 which = to 373.5in³</h3><h3>r³= 373.5in³/π</h3><h3>r=∛(373.5in³/π)</h3><h3>calculate r and times the result by 2 for diameter</h3><h3>it will be 9.834...</h3><h3>nearest tenth of an inch means the accuracy is 1 decimal place because nearest tenth= 1/10 or 0.1</h3><h3>So the final answer is 9.8in</h3>

Which of the following graphs shows the solution for the inequality. y-4&gt;2(x+2)
Crazy boy [7]

Answer:

C.

Step-by-step explanation:

First, isolate the y:

y-4>2(x+2)

y-4>2x+4

y>2x+8

First, since there is no "equal to", we can ignore B and D since their lines are shaded.

Since the y is greater than, we need to pick the graph that is shaded above the line.

The answer is C as the shaded portion is above the graph and the graph is dotted.

What is the value of a for the exponential function in the graph represented in the form of f(x)=a(b^x)
Rina8888 [55]

<em><u>Note: The complete question, along with the graph, is attached below.</u></em>

<em><u /></em>

Answer:

The value of a = 3

Step-by-step explanation:

Given the function

f\left(x\right)=a\left(b^x\right)

From the attached graph, it is clear that

at x = 0,

f\left(0\right)=a\left(b^0\right)

\:f\left(0\right)\:=\:a\:\times \:1         ∵ b^0=1

f\left(0\right)=a

Thus

When x = 0, the y-intercept will be:

f\left(0\right)=a

From the attached figure, it is clear that

at x = 0, the value of y = 3

so

putting y = 3 in the equation

f\left(0\right)=a

3 = a            ∵ f\left(0\right)=y=3

Therefore, the value of a = 3
