Jeremy bought a new truck for $32,000. The value of the truck after t years can be represented by the formula V = 32,000(.8)^t.

blondinia [14]

$6700=32000(0.8)^t$
divide both sides by 32000
$\frac{67}{320}=0.8^t$
take the ln of both sides
$ln( \frac{67}{320})=ln(0.8^t)$
using the property that $ln(a^b)=b(ln(a))$
$ln( \frac{67}{320})=t(ln(0.8))$
divide both sides by ln(0.8)
$\frac{ln( \frac{67}{320}) }{ln(0.8)} =t$
use calculator
7.00728=t
so in about 7 years

Grace uses a different way to divide 2.16 by 0.25 .She divides both the divisor and dividend by 0.01 to make an equivalent probl

liraira [26]

Answer:

8.64. Her work is correct

Step-by-step explanation:

Given the expression to divide 2.16 by 0.25

Dividing both expressions to a whole number by dividing them by 0.01 is true as shown;

2.16/0.25 = (2.16/0.01)÷(0.25/0.01)

(2.16/0.01)÷(0.25/0.01) = 216/25

216/25 = 8.64

Hence her value is 8.64 making her work correct

6 A U 3 3 1 2 3 What is the equation of the line in slope-intercept form? The equation of the line is

AleksandrR [38]

Answer:

$y = -\frac{5}{4} x+5$

Step-by-step explanation:

1) First, find the slope of the line by using two points on the graph. We can see that (0,5) and (4,0) are clearly marked on the line, so let's use those points. Use the slope formula $m = \frac{y_2-y_1}{x_2-x_1}$ and substitute the x and y values of those points into it, then simplify:

$m =\frac{0-5}{4-0} \\m = \frac{-5}{4}$

So, the slope is $-\frac{5}{4}$ .

2) Now, identify the y-intercept on the graph. The y-intercept is the point at which the line intersects the y-axis. By reading the graph, we can see that the line intersects the y-axis at (0,5), so that must be the y-intercept.

3) Substitute values for $m$ and $b$ in the slope-intercept formula, $y = mx + b$ , to write the equation of the line. Since $m$ represents the slope, substitute $-\frac{5}{4}$ for it. Since $b$ represents the y-intercept, substitute 5 in its place. This gives the following answer and equation in slope-intercept form:
