give me steps on how to solve this problem please! i’m a junior currently learning Exponential Functions.
Question:
solve 81^x = 27^(x+2)

Answer:

There were 86 problems on the test.

Step-by-step explanation:

72/87 = y/100

You use cross multiplication to solve. When you do this, you get the answer 86.75 problems, but since you can't have .75 of a problem, the answer is 86.

Answer:

13.6

Step-by-step explanation:

We can use the pythagorean therom since we know the 2 side leanths and solve for the longest side of the triangle which is the rectangle cut diagonally

11^2+8^2=c^2

121+64=c^2

185=c^2

√185= √c^2

13.6=c

Hope that  helps !

Answer:

I think its 3p not sure but u can try that

[tex]4c \: + 18 = 74[/tex]

[tex] \implies \: 4c = 74 - 18[/tex]

[tex] \implies \: 4c = 56[/tex]

[tex] \implies \: c = \cancel \dfrac{56}{4} [/tex]

[tex] \implies \: c = 14[/tex]

The value of c is 14 .

Answer:

14

Step-by-step explanation:

move all terms that don't contain c then solve.

Answer:

The third piece must be 14.4 inches

Step-by-step explanation:

We use the triangle inequality theorem to get the third side

using the theorem, it must be that the sum of the two will be greater than the length of the third side

Hence we have it that;

a + b > c

6.5 + 8.1 > c

14.6 > c

So what this mean is that the third length is less than 14.6

the reasonable answer out of the options is thus 14.4 inches

reason for this is that the last two options will also not follow the inequality theorem

Answer:

B = 53 degrees

Step-by-step explanation:

37+90=127

180-127=53

If the measure of the angle ∠A is 37°. Then the measure of the angle ∠B will be 53°.

It's a form of a triangle with one 90-degree angle that follows Pythagoras' theorem and can be solved using the trigonometry function.

Complementary angle - Two angles are said to be complementary angles if their sum is 90 degrees.

In the right triangle ΔABC, the measure of the angle ∠A is 37°.

Angle A and angle B are complementary angles. Then the equation is given as,

∠A + ∠B = 90°

37° + ∠B = 90°

∠B = 90° - 37°

∠B = 53°

If the measure of the angle ∠A is 37°. Then the measure of the angle ∠B will be 53°.

Answer:

the average change in stock prices over the two days is -155

Step-by-step explanation:

The computation of the average change in stock price over the two days is shown below:

= (-One day points - second day points) ÷ number of days

= (-250 points - 60 points ) ÷ 2 days

= -310 points ÷ 2 days

= -155

Hence, the average change in stock prices over the two days is -155

We simply applied the above formula so that the average change could come

Why is 41,250 written as 4.125 x 104 in scientific notation?

Answer:

y = 15

x = 43

Step-by-step explanation:

this is giving us a system of equations because we know two things:

x + y = 58

x - y = 28

take the second equation and format it where you have simplified it for one variable:

x = 28 + y

(we did this by adding y to both sides)

now substitute this new value of x into the first equation:

28 + y + y = 58

simplify this to get 2y = 30

divide both sides by 2: y = 15

now substitute your new value of y into the second equation:

x = 28 + 15

x = 43

Explanation:

Apply Distributive Law: a(b + c) = ab + ac

x(x + 2) = xx + x · 2

Simplify:

x² + 2x

Apply Distributive Law: a(b - c) = ab - ac

x(2x - 5) = x · 2x - x · 5

Simplify:

2x² - 5x

Apply Distributive Law: a(b + c) = ab + ac

2x(3x + 4) = 2x · 3x + 2x · 4

Simplify:

6x² + 8x

Apply Distributive Law: a(b - c) = ab - ac

Step-by-step explanation:

Distance around entire school track  = 2232.48 meters

In geometry, the perimeter of a shape is defined as the total length of its boundary. The perimeter of a shape is determined by adding the length of all the sides and edges enclosing the shape. It is measured in linear units of measurement like centimeters, meters, inches, or feet.

Given,

Straight length of the track = 1000 meters on each side

total straight length = 2 × 1000 = 2000 meters

Curves are semicircles on each side having diameter of 74 meters

which makes a complete circle

Perimeter of circle = π × diameter

                               = π × 74 = 232.477856 meters

Total distance in meters = 2000 + 232.477856

                                        = 2232.477856

Hence, 2232.48 meters is the total distance around the entire track.
