ASHA 777 [7]

Step-by-step explanation:

Let imagine a circle with a center 5,3.

Let our circle have a radius, that passes through 1,2.

We need to find the length of r or distance from 5,3 to 1,2.

$d = \sqrt{(3 - 2) {}^{2} + (5 - 1) {}^{2} }$

$d = \sqrt{1 {}^{2} + {4}^{2} }$

$d = \sqrt{17}$

So the radius is sqr root of 17.

So now we have a circle that has a radius of sqr root of 17 and a center 5,3. Let have a line passing through 5,3 and 1,2 as well.

The slope is 1/4 so

$y = \frac{1}{4} x + \frac{7}{4}$

Look at first photo

Now,we are rotating 90 degrees So we need to find a line that is perpendicular to our orginal line and that pass through the center (5,3)

Negative reciprocal slope of 1/4 is -4 and our point is 5,3 so

$y - 3 = - 4(x - 5)$

$y = - 4x + 23$

The point that intersects the circle will be the new image after we rotate (1,2) 90 degrees, which is the 2nd photo.

To find the next rotated point of (2,3), the distance of the preimage (2,3) and new image (5,3) is 3 so that leaves

(5,0)

So our new rotated points are

(6,-1)

(5,0)

How to solve -5x+9y=7 and 5x-4y=-17

Ivenika [448]

Answer is (-5,2)

You would use the elimination method and then you would find y and then plug the number in to find x. If you need help still just tell me.

Blababa [14]

Answer:

b. 0.055

Step-by-step explanation:

The point estimate of the proportion of people who wear hearing aids is

The number of people in the sample who wear hearing aids divided by the total number of people in the sample.

In this problem, we have that:

Sample of 855.

47 people in the sample had hearing aids.

47/855 = 0.0549

Rounding up

0.055

So the correct answer is:

b. 0.055

1) Billy walks 15 miles every day to soccer practice, and catches a ride home from his grandma. Billy had 5 practices last week.

nignag [31]

1 ) Billy walks 15 miles every day to soccer practice and he had 5 practices last week.

We know that, 1 mile = 1760 yards

So, 15 miles = (15× 1760) yards = 26400 yards

Thus the total distance walked in 5 practices will be: $(26400*5)yards = 132000 yards$

2) Mark's current age is $t$ years

So, his age was in 10 years ago $=(t-10)years$

Given that, his current age is 3 times his age 10 years ago.

So, the equation to represent this situation will be : $t= 3(t-10)$
