A value that "lies outside" (is much smaller or larger than)

All the 5th graders at Lincoln Elementary School will go on a field trip to the science museum. Counting all the children, teach

user100 [1]

The answer must be a whole number because for example how are you suppose to fit half a child on a bus that can hold 44 people when it already holds that amount.

It will always be a whole number because if there are several left over students they will be put in another bus with more empty seats.

A car bought for $13,000 depreciates at a rate of 15% per year. Use an exponential function to find the value of the car after 5

anygoal [31]

Answer:

$ 11093

Explanation:

Recall that the formula for compound interest is:

A = P ( 1 + r/ n ) n ( t )

−−−−−−−−−−−−−−−−−−−−−−

where:

A = future value

P = principal (starting) amount

r = annual interest rate, expressed as a decimal

n = number of times the interest is compounded in a year

t = number of years compound interest occurs for

1 . Start by substituting your known values into the formula. Note that the annual interest rate is − 0.15 since the car depreciates (becomes lower in value) each year.

A = 25000 ( 1 + − 0.15 1 ) 1 ( 5 )

2 . Solve for A .

A = 25000 ( 0.85 ) )5

A = 11092.63

A ≈ $ 11093 a

Which of the following equations represents a line that is perpendicular to y=-4x+9 and passes through the point, (4,5)?

kap26 [50]

Answer:

$y = \frac{1}{4}x + 4 \\or\\4y = x + 16$

Step-by-step explanation:

Given equation of line is:

y = -4x+9

Comparing it with the standard form

y = mx+b

m = -4

As we know that the product of slopes of perpendicular lines is -1

Let m1 be the slope of perpendicular line

m * m1 = -1

-4 * m1 = -1

m1 = -1/-4

m1 = 1/4

In order to find the value of b, putting the point in standard form

5 = (1/4)*4 + b

5 = 1 + b

b = 5-1

b = 4

Putting the value of b and m1 in standard form

$y = \frac{1}{4}x + 4 \\or\\4y = x + 16$ ..
