Answer:

D: (x – 7)2 + (y + 2)2 = 52

Step-by-step explanation:

Circle: (x -h)² + (y - k)² = r²    center (h , k)    r: radius

(1 , -6) on the circle: radius   √(1 - 7)² + (-6 - (-2))² = √36 + 16 = √52

(x -7)² + (y +2)² = (√52)² = 52

2. Find the value of x.<br> (1 point)<br> (5x)<br> (3x+28)<br> O 14<br> O20<br> O 12<br> O 19
nata0808 [166]

Answer:

x = 14

Step-by-step explanation:

The triangle has 2 congruent legs and is isosceles with 2 base angles being congruent , then

5x = 3x + 28 ( subtract 3x from both sides )

2x = 28 ( divide both sides by 2 )

x = 14

Please help m solve this it's about shaded areas. I need it fast. PLZ HELP THANK YOU IF YOU DO AND U R SO AMZING IF U DO&gt;
sukhopar [10]

A = area of the circle

A = pi*r^2

A = pi*11^2

A = 121pi

-----

B = area of the rectangle

B = length*width

B = 6*4

B = 24

-----

C = blue shaded area

C = A - B

C = 121pi - 24 which is the exact area in terms of pi

C = 356.1327 is what you'd get if you used a calculator

C = 356.13 is the result after rounding to the nearest hundredth

<h3>The final answer is 356.13</h3>

In this exercise, we are conducting many hypothesis tests to test a claim. Assume that the null hypothesis is true. If 400 tests
Brums [2.3K]

Answer:

Since the null hypothesis is true, finding the significance is a type I error.

The probability of the year I error = level of significance = 0.05.

so, the number of tests that will be incorrectly found significant is computed as follow: 0.05 * 100 = 5

Therefore, 5 tests will be incorrectly found significant given that the null hypothesis is true.
