8.2(d + 87.8) + –61 = –42.96

Answers

Answer 1
Answer:

first you will do dispurtive property.

8.2× D = 8.2d. 8.2×87.8=719.96

next you will write your equation down

8.2d+719.97+-61=42.96

you want the variable to be on the LEFT side so to isolate the variable you want to subtract the 719.97+-61= 658.97

now you bring the 658.97 to the right side.

42.96+658.97=701.93

now you divide

85.60

Answer 2
Answer:

Answer:-32 8/205

Step-by-step explanation:

I solved for d, I hope that is what you are asking. First, I divided -41.96 by 8.2. Then added 61. now the (d+87.8) is by itself. then I just subtracted 87.8. my final answer was -32.03902439024. I simplified it but if you need the long answer there it is. I did not round my answer in between steps at all. I hope this helped! GL!

Find the value of f(5) for the function
f(a)=5(a+1)-6

Answers

Answer:

To find the value of f(5) for the given function f(a) = 5(a + 1) - 6, you simply need to substitute the value a = 5 into the function and then solve for f(5).

Step-by-step explanation:

Given the function:

f(a) = 5(a + 1) - 6

To find f(5), you need to substitute the value a = 5 into the function.

Start with the original function:

f(a) = 5(a + 1) - 6

Replace 'a' with 5:

f(5) = 5(5 + 1) - 6

Simplify the expression inside the parentheses:

f(5) = 5(6) - 6

Now, perform the multiplication:

f(5) = 30 - 6

Finally, subtract 6 from 30:

f(5) = 24

So, the value of the function f(5) is 24. This means that when the input value is 5, the function evaluates to 24.

Answers

Answer:

Step-by-step explanation:

Analyzing the growth rate of 1.07:

If the growth rate is a number greater than 1, we have exponential growth; if the growth rate is a number greater than 0 but less than 1, we have exponential decay.

Our growth rate is actually growth.  But the rate of growth is not 107%.  The rate of growth means that we already had 100% of the population and that it is growing by 7% each year.  100% + 7% = 107%; as a decimal, 1.07

So the rate of growth is 7%

X to the forth power ÷ 3+9 when x=3​

Answers

3^4/3+9
81/3+9
27+9=36
answer=36

Answer:

36

Step-by-step explanation:

Ok, so the expression we are given is x^(4) ÷ 3 + 9.

We know that x = 3, so we need to substitute 3 in as x.

So, now the expression looks like 3^(4) ÷ 3 + 9.

Now we can solve this expression.

First we need to figure out what  3^(4) is equal to.

1.  3^(4) = 81

We're left with 81 ÷ 3 + 9.

Next, we need to divide our 81 by our 3.

2.  81 ÷ 3 = 27

Our new expression is 27 + 9.

Last, we need to add our 27 and our 9 together.

3.  27 + 9 = 36

Our answer is 36.

So x^(4) ÷ 3 + 9 when x = 3 is 36.

Sin(A+B)/sin A cos B
= 1 + cot A tan B
how to verify the identity?

Answers

Answer:

see explanation

Step-by-step explanation:

Using the identities

sin(A + B) = sinAcosB + cosAsinB

cotA = (cosA)/(sinA) , tanA = (sinA)/(cosA)

Consider the left side

(sin(A+B))/(sinAcosB)

= (sinAcosB+cosAsinB)/(sinAcosB)

= (sinAcosB)/(sinAcosB) + (cosAsinB)/(sinAcosB)

= 1 + (cosA)/(sinA) . (sinB)/(cosB)

= 1 + cotA tanB = right side , thus verified
