Answer:

Ans: -21.87 ≅ -22°C

Step-by-step explanation:

T(x)=-22+44e^-0.03x

 

Initial temperature (x = 0):

 

T(0) = = -22 + 44e-0.03(0) = -22 + 44(1) = 22°C

 

After 18 minutes (x = 18):

 

T(18) = -22 + 44e-0.03(18) = -21.87°C ≅ -22°C

Which of the following are right triangle congruence theorems
Molodets [167]

<u>Answer:</u>

The correct answer options are A, B, C and D.

<u>Step-by-step explanation:</u>

A. Leg-angle (LA):

According to this theorem, if the leg and an acute angle of one right triangle are congruent to the corresponding leg and acute angle of another right triangle, then the triangles are congruent.

B. Hypotenuse-leg (HL):

If any two right triangles that have a congruent hypotenuse and a corresponding, congruent leg are congruent triangles.

C. Hypotenuse-angle (HA):

If the hypotenuse and an acute angle of one right triangle are congruent to the hypotenuse and an acute angle of another right triangle, then the two triangles are congruent.

D. Leg-leg (LL):

If any two right triangles that have a congruent hypotenuse and a corresponding, congruent leg are congruent triangles.

Annual sales for a company are $125,000 and are increasing at a rate of 8% per year. Use an exponential function to find the ann
xxTIMURxx [149]

Answer:

sales after 5 years is $183666

Step-by-step explanation:

exponential function standard form:

a=P(1+r)^t

where p=principal(starting amount)(125,000)

r=rate of change(0.08)

t=time(5)

so

a=125,000(1+0.08)^5

a=125,000(1.08)^5

a=125,000(1.46)

a=183666

7n^2-4n-14=21<br> complete the square
Galina-37 [17]
Answer: (7n - 2)² = 249

Explanation:

1) Given expression: 7n² - 4n - 14 = 21

2) Transpose  - 14 =>

7n² - 4n = 21 + 14

3) Combine like terms =>

7n² - 4n = 35

4) multiply both terms by 7 =>

(7n)² - 4(7n) = 35×7

5) form the squared binomial:

(7n - 2)² - 4 = 35×7

6) Transpose - 4 =>

(7n - 2)² = 35×7 + 4

7) Do the operations on the right side:

(7n - 2)² = 249 or (7n - 2)² - 249 = 0

8) Verify the equivalence by expanding the binomial:

(7n)² - 2(7n) + 4 - 249 = 0

(7n)² - 14n - 245 = 0

Divide by 7: 7n² - 2n - 35 = 0 or 7n² - 2n = 35, which is equivalent to the given expression.
