Answer:

A) -5

Step-by-step explanation:

Note the slope intercept form:

y = mx + b

y & x is found from having a pt. (x , y)

m = slope

b = y-intercept.

Note that to find the slope, you must find the number that is directly left of the variable, x. In this case, it is -5.

A) -5 is your answer.

Mr. Winking is purchasing a car and needs to finance $24,000 from the bank with an annual percentage rate (APR)

babymother [125]

Answer:

<em>The monthly payment is $450.71</em>

Step-by-step explanation:

<u>Financial Computing </u>

Given the loan amount A, the loan term t, and the APR (annual percentage rate), the montly payment is computed as

$\displaystyle P=\frac{A}{f}$

where f is

$\displaystyle f=\frac{1-(1+i)^{-n}}{i}$

The provided data is

$\displaystyle A=24,000$

$\displaystyle r=4.8\%$

$\displaystyle t=5\ years$

Since the payments will be made monthly, the values of n and i are:

$\displaystyle i=\frac{4.8}{100\times12}=0.004$

$\displaystyle n=5\times12=60\ months$

Calculating f:

$\displaystyle f=\frac{1-(1+i)^{-n}}{i}$

$\displaystyle f=\frac{1-(1+0.004)^{-60}}{0.004}$

$\displaystyle f=53.25$

Now for the payments:

$\displaystyle P=\frac{24.000}{53.25}=450.71$

$\boxed{\displaystyle P=\$450.71}$

Determine if its possible to form a triangle using the set of segments with the given measurement. explain please! 7 in., 8.7.,

mafiozo [28]

Start by adding together the shortest two sides, 7 and 8.7 inches. Result: 15.7 inches. Because this sum is greater than the longest side, 15.4 inches, it's possible to construct a triangle, whose largest angle will be close to 180 degrees.

Answer:

Y(n) = 400(2.5)^n

Y = 3,814,697 rice weevils

16.1 weeks

Step-by-step explanation:

To predict the population of rice weevil for any week after the start of the study ; wwe use an exponential function for this purpose :

y(n) = A(1 + r)^n

Where;

Y(n) = population at week n

r = growth rate ; n = number of weeks

A = initial population at the start of the study

r = 150% = 1.5

Hence, we have the equation :

Y(n) = 400(1 + 1.5)^n

Y(n) = 400(2.5)^n

B.)

Population after 10 weeks

n = 10

Y(10) = 400(2.5)^10

Y = 400 * 9536.7431640625

Y = 3814697.265625

Y = 3,814,697 rice weevils

When population will reach 1,000,000,000

We have :

1,000,000,000 = 400(2.5)^n

1000000000 / 400 = 2.5^n

2500000 = 2.5^n

Take the log of both sides :

log(2500000) = nlog(2.5)

6.3979400 = n * 0.3979400

n = 6.3979400 / 0.3979400

n = 16.077649

n = 16.1 weeks approximately
