Answer:

The answer is 13. She has 23 coins and it equals $4.25. So, if she has 10 dimes, that would equal $1 and if she has 13 quarters, that would equal $3.25.

Hey there!

To start, the domain of a function is the set of x values a function has, in other words, the values the function has on the x-axis.

In this function, the graph appears to have a function going on infinitely in both directions (left and right). Because of this, your domain in interval notation would be (-∞,∞)

**Your interval notation would be in parenthesis because you cannot include negative or positive infinity as one of your values since while your graph is approaching these values, it never really reaches it.

Hope this helps and have a wonderful day! :)

Find the value of c if a line with slope 3/4 passes through the points (1,8) and (5,c) PLEASE HELP

seropon [69]

The value of c, if a line with a slope of 3/4 that passes through the points (1,8) and (5,c), is 11.

<h3>What is the equation of a line?</h3>

A line is a one-dimensional shape that is straight, has no thickness, and extends in both directions indefinitely. The equation of a line is given by,

y =mx + c

where,

x is the coordinate of the x-axis,

y is the coordinate of the y-axis,

m is the slope of the line, and

c is the y-intercept.

Given that the line has a slope of 3/4 and passes through the point (1,8). Therefore, we need to substitute the slope and the coordinates in the equation of the line, to get the value of the y-intercept.

y = mx + c

8 = (3/4)(1) + c

8 = (3/4) + c

c = 8 - (3/4)

c = 29/4

Now, the line also passes through (5,c), therefore, if we substitute the value of slope and y-intercept in the equation,

y = mx + c

c = (3/4)(5) + (29/4)

c = (15/4) + (29/4)

c = 44/4

c = 11

Hence, the value of c, if a line with a slope of 3/4 that passes through the points (1,8) and (5,c), is 11.

Quickly plz What is the value of x? O liv units O 2 13 units O 2/3 units O 3v3 units

Answer:

$x=3\sqrt{2}\\$

Step-by-step explanation:

Since the smaller triangles have a side of the same length, they share one side, and the included angle is 90°, the triangles are congruent.

This means the length of the side to the left is also x as shown in the image below.

The bigger triangle is also right and has side lengths of x, x, and 6 (the hypotenuse), thus:

$x^2+x^2=6^2$

Operating:

$2x^2=36$

$x^2=18$

Since 18=9*2

$x=\sqrt{9*2}$

$\mathbf{x=3\sqrt{2}}$

The options are not clear enough, so I cannot make a choice.

What is the area of a regular 16-gon with a radius of 15 feet? Round your answer to the nearest tenth.

Sedbober [7]

Split up the 16-gon into 16 congruent isosceles triangles. Cut each of these isosceles triangles in half to get a right triangle.

The radius of the 16-gon corresponds to the hypotenuse of any of these 32 right triangles. As you probably know, the area of a triangle is half the product of its base and height. For a right triangle, the base and height can be taken to be the two legs. So you need to find their lengths.

Recall that the exterior angles of any convex polygon sum to 360º in measure. For a regular polygon, these angles are all congruent. There are 16 of them in this case, so they each have measure (360/16)º = 22.5º.

Interior angles are supplementary to exterior angles, which means each interior angle of the 16-gon has measure (180 - 22.5)º = 157.5º.

When we split up the 16-gon into isosceles triangles, the "base angles" are equal in measure to half the measure of the interior angles, since each hypotenuse bisects the interior angle. So each base angle has measure 78.75º.

In each right triangle, we then have base b and height h such that

sin(78.75º) = h/15

cos(78.75º) = b/15

Solve for h and b to get

b = 15 cos(78.75º)

h = 15 sin(78.75º)

Then the area of each right triangle is

1/2 b h = 225/2 sin(78.75º) cos(78.75º) = 225/4 sin(157.5º)

and so the area of the 16-gon is

32(1/2 b h) = 1800 sin(157.5º) ≈ 688.8 sq. ft.
