Answer:

Total number of flowers: 81 + 9 = 90

81/90 × 100

0.9 × 100

So there are 90% Perennials

Two central angles are listed below.

luda_lava [24]

You have to put the two angles in the same units, because now the first one is in radians and the second one in degress.

To pass 1.38 radians to degrees you can use the ratio 180° / π radian = 1.

So 1.38 radian * 180° / 3,1416 = 79 °.

So the angle in the Column A is 2° wider than the angle in the Column B.

PLS HELP Find the area of the shaded region. PLEASE

anastassius [24]

<h3>Answer: 64 cm^2</h3>

Reason:

The parallelogram has area of A = base*height = 10*7 = 70 cm^2

The white rectangle has area of B = base*height = 3*2 = 6 cm^2

The shaded region has area of A - B = 70 - 6 = 64 cm^2

If you are curious why the rectangle and parallelogram use the same formula to get the area, notice how you can move that triangle on the left toward the right side so that a rectangle can be formed.

Given g(x)=sqrt x-4 and h(x)=2x-8 what is (g(h(10)) HELP ME I AM .3 POINTS AWAY FROM PASSING.

Whitepunk [10]

The answer (g(x))=x−7

g(f(x))=√x2−7

Explanation:

Put g inside f to find f(g(x))

f(x)=x2−4

g(x)=√x−3

f(g(x))=(√x−3)2−4

f(g(x))=x−3−4

f(g(x))=x−7

Put f inside g to find g(f(x))

g(x)=√x−3

f(x)=x2−4

g(f(x))=√x2−4−3

g(f(x))=√x2−7:

The answers are f(g(x))=x−7
and g(f(x))=√x2−7

Explanation:

This is a composition of functions.

f(x)=x2−4

g(x)=√x−3

fog(x)=f(g(x))=f(√x−3)=(√x−3)2−4

=x−3−4=x−7

And

gof(x)=g(f(x))=g(x2−4)=√(x2−4)−3

=√x2−4−3=√x2−7

You can see that

f(g(x))≠g(f(x))

If a sample of 14 students were taken from a population of 168 students, could refer to the variance of how many of the students

tensa zangetsu [6.8K]

⇒The Variance tells us spread between each variate in data set from mean.

Now, Coming to the Question

⇒Sample of 14 students were taken from a population of 168 students.

Variance =Expected value of square of each variate taken from mean, which can be represented as

$=\sum_{N=1}^{k} \frac{E(x-\mu)^2}{N}$
