A new popular midsize car has a retail price of $25,000. The midsize car's value M(t) is given by the exponential model M of t is equal to 25,000 times the quantity four fifths to the power of t where t represents the time in years. Identify the domain, in yearly intervals, that contains all the years the car's value is less than $1,000.

Answers

Answer:

Its C

Step-by-step explanation:

Just finished the homework and got it right

Using exponential functions, it is found that the correct option is given by:  [15, ∞)

-------------------------

The exponential function given in this exercise is:

[tex]M(t) = 25000(\frac{4}{5})^t[/tex]

-------------------------

The domain that contains all the years the car's value is less than $1,000 is composed by the values of t for which:

[tex]M(t) < 1000[/tex]

Thus, we have to solve the exponential inequality.

[tex]M(t) < 1000[/tex]

[tex]25000(\frac{4}{5})^t < 1000[/tex]

[tex](\frac{4}{5})^t < \frac{1}{25}[/tex]

[tex]\log{(\frac{4}{5})^t} < \log{\frac{1}{25}}[/tex]

[tex]-0.0969t < -1.39794[/tex]

[tex]0.0969t > 1.39794[/tex]

[tex]t > \frac{1.39794}{0.0969}[/tex]

[tex]t > 14.43[/tex]

Rounding, t greater than 15 years, and the correct option is:

Solve for x.

3(x-1)-8=4(1+x)+5

Also could someone please explain how to do this??

Answers

9514 1404 393

Answer:

  x = -20

Step-by-step explanation:

First, simplify the equation. Eliminate parentheses and combine terms.

  3(x -1) -8 = 4(1 +x) +5 . . . . . . . given

  3x -3 -8 = 4 +4x +5 . . . . . . . . eliminate parentheses (distributive property)

  3x -11 = 4x +9 . . . . . . . . . . . . combine like terms

We can put all the x-terms on the right by subtracting 3x from both sides.

  3x -11 -3x = 4x +9 -3x

  -11 = x +9

And we can get the x-term by itself by subtracting 9 from both sides.

  -11 -9 = x +9 -9

  -20 = x . . . . . . . . . . this is the solution

__

Check

3(-20 -1) -8 = 4(1 -20) +5

3(-21) -8 = 4(-19) +5

-63 -8 = -76 +5

-71 = -71 . . . . . . . . . true, the answer checks OK

_____

Additional comment

We observe that the two x-terms are 3x and 4x. The smaller of these is 3x, so when we subtract that from 4x we will have a positive result. That is why we chose to subtract 3x, even though it leaves the x-term on the right side of the equation. We could have subtracted 4x to get -x -11 = 9. I find it easier not to make a mistake if the variable has a positive coefficient.

Find the distance between the pair of points. Round your answer to the nearest tenth if necessary.

Answers

Answer:

The distance between the pair of points is 12.0 (to the nearest tenth)

Step-by-step explanation:

The distance between a pair of points in a coordinate system is found by the formula:

d =[tex]\sqrt({x_2-x_1)^2+(y_2-y_1)^2}[/tex]

where, the points are:

[tex](x_1,y_1)\ and\ (x_2,y_2)[/tex]

From the graph,

[tex](x_1,y_1)=(-6,-2)\\(x_2,y_2)=(2,7)[/tex]

Substitute the points into the formula:

[tex]d=\sqrt{(2-(-6)^2+(7-(-2)^2} \\d=\sqrt{(2+6)^2+(7+2)^2} \\d=\sqrt{8^2+9^2} \\d=\sqrt{64+81} \\d=\sqrt{145} \\\d=12.0[/tex]

For:

Express into fractions:

substitute for b as 2a from equation (n):

[tex] = \frac{(3a + 2a)}{(4a + 4a)} \\ \\ = \frac{5a}{8a} \\ \\ = \frac{5}{8} [/tex]

Find the total surface area of the following cone. Leave your answer in terms of Pi. 4cm 3cm

Answers

The triangle formed from the height of the cone and the radius of its base is a special 3,4,5 triangle. The slant height is 5cm.

Recall that the area of a circle = pi*r^2

Substitute 3 in for r

Area = pi * (3)^2 = 9pi

SA = pi*r*l + B

Substitute our values into the equation

SA = pi * 3 * 5 + 9pi

SA = 15pi + 9pi

SA = 24pi cm^2
