15 m

explanation:

Let AB and CD be the pole and tower respectively. Let CD=h Then ∠DAC=60 ∘ and∠DBE=30 ∘ Now CA CD ​ =tan60 ∘ = 3 ​ ∴CD= 3 ​ CA⇒ 3 ​ h ​ =CA Again BE DE ​ =tan30 ∘ = 3 ​ h ​ ∴(h−10)= 3 ​ BE ​ = 3 ​ CA ​ ...[∵BE=CA] = 3 ​ h/ 3 ​ ​ = 3 h ​ ⇒3h−30=h⇒2h=30⇒h=15

Hence, height of the power =15 m

Answer:

answer would be 120 degrees.

Step-by-step explanation:

because 4y+4+60=180

angle Q =4y+4

so 180-60=120

You will have to pay back a total of $464 over the course of the two-year loan, which includes the $400 principal plus $64 in interest.

What is Simple Interest ?

Simple interest can be defined as the ratio of product of principal amount , rate , time and hundred.

The interest on your loan can be calculated using the formula:

Interest = Principal x Rate x Time

In this case, the principal is $400, the rate is 8% (or 0.08 as a decimal), and the time is 2 years.

So, plugging in the numbers:

Interest = $400 x 0.08 x 2 = $64

Therefore, the total amount you will have to pay back is the sum of the principal and the interest, which is:

Total = Principal + Interest

= $400 + $64 = $464

Hence, You will have to pay back a total of $464 over the course of the two-year loan, which includes the $400 principal plus $64 in interest.

Answer:

Slope: undefined

Equation: x=-3

Step-by-step explanation:

To find the line that passes through the points, you first want to find the slope.  The formula for slope is [tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]. Once we have the slope, we can use any given point to plug in to find the y-intercept.

[tex]m=\frac{-5-9}{-3-(-3)} =\frac{-14}{0}[/tex]

We can see that the slope is undefined. If we look at the point, we notice that they both have the same x-coordinate. This let's us know that the equation is x=-3.

Step-by-step explanation:

parallel lines have the

8/3x-2/3 is the slope-intercept form of the line that passes through (1, 2) and is parallel to the graph of y= 8/3x.

The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.

The slope intercept form of a line is y=mx+b, where m is slope and b is the y intercept.

The slope of line passing through two points (x₁, y₁) and (x₂, y₂) is

m=y₂-y₁/x₂-x₁

We need to find the slope-intercept form of the line that passes through (1, 2) and is parallel to the graph of y= 8/3x.

The slopes of parallel lines will be same.

Firstly let us find y intercept.

2=8/3(1)+b

2-8/3=b

-2/3=b

Hence, 8/3x-2/3 is the slope-intercept form of the line that passes through (1, 2) and is parallel to the graph of y= 8/3x.

Answer:

y= -x + 10

Step-by-step explanation:

At 0 hours = Bob has 10 apples

At 4 hours = Bob has 6 apples

In 4 hours Bob has eaten 4 apples

Using linear graphs where y = the apples remaining and x = the hours passed

y = mx + c

We already know some coordinates:

(0,10) - 0 hours 10 apples remaining

(4,6) - 4 hours 6 apples remaining

c is the y intercept and m is the gradient

We already have the y intercept (where x = 0) which is (0,10)

So first part of our rule is done: y = mx + 10

The gradient is rise / run

Rise = -4 and Run = 4

-4/4 = -1

So the gradient is -1 and we add that to our rule

So final rule is y = -x + 10

8-(-12)/17-17 = 0

The line containing (17, -12) and (17, 8) has no slope.

The line is a vertical line with an x-intercept at x = 17.

The equation of a line is given by:

y = mx + c

where m is the slope of the line and c is the y-intercept.

Example:

The slope of the line y = 2x + 3 is 2.

The slope of a line that passes through (1, 2) and (2, 3) is 1.

We have,

A line contains two points.

(17, -12) and (17, 8).

Consider,

(17, -12) = (a, b) and (17, 8) = (c, d)

The slope of the line.

Slope:

= (d - b) / (c - a)

= (8 - (-12)) / (17 - 17)

= 8 + 12 / 0

= 20 / 0

= undefined.

This means there is no slope for the line that contains (17, -12) and (17, 8).

The line is a vertical line intercepting at x = 17.

Thus,

The line containing (17, -12) and (17, 8) has no slope.

The line is a vertical line with an x-intercept at x = 17.
