HELPPP <br><br> Solve for b 2 in A = h(b 1+b 2), if A = 16, h = 4, and b 1 = 3.<br><br> b 2 =

Lilit [14]

Answer:1

Step-by-step explanation: substitute all the corresponding terms so you get, 16=4(3+b2)

Then you multiply and get 16=12+4b2 then subtract 12 from both sides to get 4=4b2 and then divided both sides by 4 and you get 1=b2

Type the correct answer in the box. Use numerals Instead of words. If necessary, use / for the fraction bar.

Zielflug [23.3K]

Using an exponential function, it is found that the value of David's Investment will be at least $415 after a period of 20 years.

<h3>What is an exponential function?</h3>

An increasing exponential function is modeled by:

$A(t) = A(0)(1 + r)^t$

In which:

A(0) is the initial value.

r is the growth rate, as a decimal.

In this problem, the initial value and the growth rate for his investment are given by:

A(0) = 230, r = 0.03.

Hence, the value after t years is given by:

$A(t) = 230(1.03)^t$

Then, the value will be of at least $415 when:

$A(t) \geq 415$

$230(1.03)^t \geq 415$

$(1.03)^t \geq \frac{415}{230}$

$\log{(1.03)^t} \geq \log{\frac{415}{230}}$

$t\log{1.03} \geq \log{\frac{415}{230}}$

$t \geq \frac{\log{\frac{415}{230}}}{\log{1.03}}$

$t \geq 20$

Write the equation of the line that passes through the points (-3, 4) and (-3,3)

Phantasy [73]

Answer:

first determine the gradient because the equation of a straight line is y=mx+c

therefore gradient=change in y/change in x

=y2-y1/x2-x1

=4-3/-3-(-3)

=1/0

there fore gradient of the line is undefined

y=x+c

4=-3+c

4+3=c

7=c

therefore y=x+7
