X=4
If you plug in 4 for x you should get 49 which would add up with the other angles to equal 180

20 points! Write an exponential function in the form y=ab^x that goes through points (0, 8) and (2, 200)

alexandr402 [8]

Answer:

$y=8(5)^x$

Step-by-step explanation:

We want an exponential function that goes through the two points (0, 8) and (2, 200).

Since a point is (0, 8), this means that y = 8 when x = 0. Therefore:

$8=a(b)^0$

Simplify:

$a=8$

So we now have:

$y = 8( b )^x$

Likewise, the point (2, 200) tells us that y = 200 when x = 2. Therefore:

$200=8(b)^2$

Solve for b. Dividing both sides by 8 yields:

$b^2=25$

Thus:

$b=5$

Hence, our exponential function is:

$y=8(5)^x$

What is the approximate length of the hypotenuse of a right triangle with vertices (-6, 2),

muminat

Answer:

Step-by-step explanation:

A(-6, 2), B(6,-3) and C(-6, -3)

AB² = (x₂ - x₁)² + (y₂ - y₁)²

= ( 6 -[-6])² + ( -3 -2)²

= ( 6 + 6)² + ( -3 -2)² = 12² + (-5)² = 144 + 25 =169

AB = √169 = 13 units

BC² = ( -6 -6)² + ( -3 - [-3])² = (-6-6)² + (-3 +3)²

= (-12)² + 0 = 144

BC = √144 = 12 unis

CA² = (-6 - [-6])² +(-3-2)² = (-6 + 6)² + ( -3-2)²

= 0 + (-5)² = 25

CA =√25 = 5 units

length of the hypotenuse of a right triangle = 13units

Let C ( t ) be the number of US cell phone subscribers in millions in t years since 1995. A linear model for the data is F ( t )

Andru [333]

ANSWER

In 16 years time.

EXPLANATION.

If the number of subscribers is 324 million, then it means

$f(t)=324$

But we were given that,

$f(t)=18.997t+16.711$

This implies that,

$324=18.997t+16.711$

We now solve for t,

$324-16.711=18.997t$

$307.289=18.997t$

$\frac{307.289}{18.997}=t$

$16.17566=t$

That will be approximately in the 16th year.
