Please help me i dont know what the answer is ??

Answers

Answer 1

Answer: To answer this, we need to use the rules of geometric shapes. An equilateral triangle is equiangular, meaning all its angle measures are equal. Since all triangles' angles add up to 180°, simply divide 180 by three to find the angle measure of each angle:
$(180)/(3) = 60$
Therefore, the measure of the triangle's angle is 60°

Next, we know that a characteristic of a rectangle is that each angle must be a right angle, or an angle with a measure of 90°.

Now, all we have to do is use the sum of all the angle measures to figure out the missing piece:
$90=x+60+12 \n 90=x+72 \n 90-72=(x+72)-72 \n 18=x$

The missing angle measure, angle x, equals 18°.

Hope this helps!

Which of the following represents exponential growth? $y = 2x + 5$
$y - x = 4$
$x = 3$
$y = 5 * 2^(x)$

Answers

Answer:

y = 5 × $2^(x)$

Step-by-step explanation:

Exponential growth equations are usually in the form y = a × $b^(x)$ .

So, y = 5 × $2^(x)$ is the best fit for that format.

Have a great day!

The exponential growth:

$y=a\cdot b^x$

Therfore your answer is $y=5*2^x$

--------------------------------------------------------

y = 2x + 5 it's a linear function in slope-intercept form

y - x = 4 → -x + y = 4 it's a linear function in standard form

x = 3 it's a vertical line

( and ) means bigger than and smaller thenWrite the resulting inequality

-5 ( -2 add 7 to both sides

-6 ( -3 divide both sides by -3

7) - 4 subtract 7 from both sides

-1 ) -8 multiply both sides by -2

!HELP! SHOW WORK PLEASE SO I CAN UDNERSTAND!A paper drinking cup in the shape of a cone has a height of 10 centimeters and a diameter of 8 centimeters. Which of the following is the closest to the volume of the cup in cubic centimeters?
167 cm³
209 cm³
670 cm³
502 cm³

Answers

Ok.

The volume of a cone is the volume of a cylinder over 3.

The volume of a cone is:
$(1)/(3) \pi r^(2)h$

This problem gives us the diameter, which is twice of the radius. So, we'll just half it.
Radius (me) = 4 cm.

Substitute our given values into the equation.
$(1)/(3) \pi (4)^(2)h \ or \ (1)/(3) \pi (4)^(2)(10) \ or \ (1)/(3) \pi (16)(10)$

Multiply
$(1)/(3) \pi(160) \ or \ (1)/(3) (3.14)(160) \ or \ 1.047(160)$

Multiply
$167.52 \ cm^(3)$

This would make $167 \ cm^(3)$ the closest option.

The formula for the volume of a cone is π r²h/3. You are given the height and the diametre of the cone. You need the radius which is half the diametre (4). So, f you were to write this out, it would look like this:

3.14 × 4² × 10/3

your answer is going to be 167 cm³

What is the image of (-5,5) after a dilation by a scale factor of 4 centered at the
origin?

Answers

The image of (-5,5) is (-20, 20).

What is image point?

Its image refers to the new position of a point, line, line segment, or figure following a transformation.

for instance, the image of the triangle A'B'C following translation is the triangle A'B'C. The images of points A, B, and C are represented by the letters A, B, and C. The images of the original line segments AB, BC, and AC are represented by the line segments A'B', B'C', and A'C', respectively.

Given coordinates (-5,5) dilation by a scale factor of 4 centered at the

origin, If a point's preimage is P(x, y), then its image after a dilation with a scale factor of k and centered at the origin (0, 0) is P′(kx, ky).

Using this rule we can find the image of (-5 , 5)

Here P(x , y) = (-5 , 5) and k = 4

So P'(x , y) = 4(-5 , 5) = (-20, 20)

Hence the new coordinates are (-20, 20).
