If Q is the midpoint of pr, find the coordinates of r if p(11,-2) and q(4,3) look

1 answer:

5 0

R is (-3,8)
to get from p’ to q’, you subtract 7 from the x’ value, and add 5 to the y’ value. so you do the same to get from q’ to r’

an isosceles triangle has a vertex angle of 21.21 degrees. two sides of the triangle are each 17.91 ft long. whats the area of t

lubasha [3.4K]

Answer:

The area of triangle is $A=58.02\ ft^{2}$

Step-by-step explanation:

Let

B -----> the measure of the vertex angle of the isosceles triangle ABC

a and c -----> the two congruent sides of the isosceles triangle ABC

we know that

The area of a triangle applying the law of sines is equal to

$A=\frac{1}{2}(a)(c)sin(B)$

we have

$a=c=17.91\ ft$

$B=21.21\°$

substitute in the formula

$A=\frac{1}{2}(17.91)(17.91)sin(21.21\°)$

$A=58.02\ ft^{2}$

For the standard normal curve, find the z-score that corresponds to the 30th percentile. -0.47 -0.98 -0.53 -0.12

Nata [24]

We are looking for the Zo score that corresponds to the 30th percentile.
We use the table for the standard normal distribution.
From P (Z <Zo) = 0.3 we search for Zo.
Then we look in the table for the value of Zo that corresponds to 0.3.
Hence, the approximate value is -0.53.
The option is the third
