lana66690 [7]

Answer:

Correct choice is B

Step-by-step explanation:

The exponential regression model can be written as exponential function

$y=a\cdot b^x.$

Then

$5,000=a\cdot b^0=a,\\ \\5,510=a\cdot b^2\Rightarrow 5,510=5,000\cdot b^2,\\ \\b^2=\dfrac{5,510}{5,000}=\dfrac{551}{500}\Rightarrow b\approx 1.05.$

Thus,

$y=5,000\cdot (1.05)^x.$

When $x=12,$ you get

$y(12)=5,000\cdot (1.05)^{12}\approx \$8,980.$

A circle is centered on point B. Points A, C and D lie on its circumference.

guapka [62]

Answer:

m∠ADC = 20°

Step-by-step explanation:

A circle B has points B, C and D on the circumference.

m∠ABC = 40° [Cntral angle]

Since measure of the central angle is double of the inscribed angle by the arc

m∠ABC = 2(m∠ADC)

Here ∠ABC = Central angle

and ∠ADC = Inscribed angle

40° = 2(m∠ADC)

m∠ADC = $\frac{40}{2}$

= 20°

Therefore, measure of angle ADC is 20°.

Answer:

Step-by-step explanation:

Because you can't do -x+1 so it would be (1,0) and then you have x^2 +3x-4 which is (-5,6)

Let x = cups of 11% wheat, and y = cups of 63% wheat

He wants 12 cups in total, so we need:

x + y = 12

These 12 cups need to have 50% wheat, which means we are looking at 12*.5 = 6 cups of wheat in total, so our second equation is:

.11x + .63y = 6

We have two equations and two variables. So we can solve by using any means you want. I used substitution:

x = 12 - y

.11(12-y) + .63y = 6

1.32 -.11y + .63y = 6

.52y = 4.68

y = 9

Which means x = 3

Thus, 3 cups of 11% and 9 cups of 63%.
