a. 8x + 4
b. 20x + 4
19x + 14
d. 8x - 20

Answer:

c. 9 det A

Step-by-step explanation:

Given the following data;

Since A is a square matrix of order 2, we know that n = 2

K = 3

For any scalar k;

∣kA∣ = k^{n} ∣A∣

Substituting into the equation;

∣-3A∣ = -3²∣A∣

Simplifying, we have;

∣-3A∣ = 9∣A∣

= 9 detA

Therefore, det (-3A) = 9 detA

Answer:

we are missing some information, so I looked for a similar question and found the attached image:

Cincinnati's total population = 298,957 people

Cincinnati's population over age 25 = 193,638

I added all the people that were up to 24 years old and then subtract that number from 298,957 - 105,319 = 193,638

Percentage of Cincinnati residents over age 25 that have a bachelor's degree or higher = 66,722 / 193,638 = 0.3446 = 34.46%

Answer:

he used 1/8 of paint .....

We would have to divide every single one of these fractions to find out if they were terminating decimal. 2/5 = 2divided by 5 = 0.4 as you can see no many other repeating numbers after the decimal. We don't have to do the rest since we now know the answer is 2/5.

The inverse function of f(x) is:

[tex]g(x) = \sqrt[3]{(x +1)/64}[/tex]

Here we have the function:

[tex]f(x) = 64*x^3 -1[/tex]

We want to find the inverse, we will say that is of the form:

[tex]g(x) = \sqrt[3]{a*x + b}[/tex]

If we evaluate f(x) on g(x), we get:

[tex]f(g(x)) = 64*(\sqrt[3]{ax + b})^3 - 1\\ \\f(g(x)) = 64*(ax + b) - 1[/tex]

If these are inverses, that must be equal to x:

[tex]64*(ax + b) - 1 = x\\\\64*a*x + 64*b - 1 = x\\[/tex]

Then:

64*a = 1

a = 1/64

64*b - 1 = 0

b = 1/64

So the inverse function is:

[tex]g(x) = \sqrt[3]{(x +1)/64}[/tex]

Answer:

C. Stretch it

Step-by-step explanation.

Answer: the answer is -2 1/3

Step-by-step explanation: it would be -2 1/3 because 5 + 2=7 and then add the 1/3 to make -7 1/3

The number that makes the equation

[tex]\rm -5 +x = -7\dfrac{1}{3}[/tex]     true is [tex]\rm \bold {-2\dfrac{1}{3} }[/tex].

So option 4 is correct.

Let the number that makes equation true is x

The question is that what makes equation true

[tex]\rm -5 +x = -7\dfrac{1}{3}[/tex]

This equation is a linear expression with one variable and rational numbers.

This equation can be solved in the following way

[tex]\rm -5 +x = -\dfrac{22}{3} \\x = 5 -\dfrac{22}{3} \\x = (15-22)/3 \\x = -7/3\\ x= -2\dfrac{1}{3}[/tex]

So from the given options in figure  we can see that option 4 is correct

Answer:

[tex](7,-11)[/tex]

Step-by-step explanation:

Given

[tex]S = (1,5)[/tex]

[tex]M = (4,-3)[/tex]

Required

Determine the coordinates of T

Midpoint is calculated as:

[tex]M(x,y) = \frac{1}{2}(x_1 +x_2,y_1+y_2)[/tex]

Where:

[tex](x,y) = (4,-3)[/tex]

[tex](x_1,y_1) = (1,5)[/tex]

Substitute these values in the above formula:

[tex](4,-3) = \frac{1}{2}(1 + x_2,5+y_2)[/tex]

Multiply through by 2

[tex]2 * (4,-3) = 2 * \frac{1}{2}(1 + x_2,5+y_2)[/tex]

[tex](8,-6) = (1 + x_2,5+y_2)[/tex]

By direct comparison:

[tex]1 + x_2 = 8[/tex] and [tex]5 + y_2 = -6[/tex]

Solving for x2

[tex]1 + x_2 = 8[/tex]

[tex]x_2 = 8 - 1[/tex]

[tex]x_2 = 7[/tex]

Solving for y2

[tex]5 + y_2 = -6[/tex]

[tex]y_2 = -6 - 5[/tex]

[tex]y_2 = -11[/tex]

Hence, the coordinates of T is: [tex](7,-11)[/tex]

Answer:

(C).The solid ball of radius 5 centered at (0,0,0) with the interior of the solid ball of radius 1 centered at (0,0,0) removed.

Step-by-step explanation:

These are the equation of Spheres

In the equation [tex]1\leq x^2 + y^2 + z^2 \leq 25[/tex], when we will take square root of 25 we will get radius as 5 so the Sphere is varying from radius 1 to 5, Which will make it into a Solid sphere with the center at (0, 0, 0)

In the equation [tex]x^2 + y^2 + z^2 \leq 25, x \geq 0[/tex] it is given that the sphere is less than

radius 5 units.

Also there will be no sphere with radius from 0 to 1 because the sphere is starting from radius 1 and increasing till radius 5.

Therefore, The sphere is a solid increasing from radius 1 to 5.

and another solid sphere is removed from inside with radius increasing from 0 to 1.
