Answer:

Step-by-step explanation:

6-3=3 then power of 2 which is 9 then plus 1

Answer 2

Answer:

Step-by-step explanation:

Substitute 6 for "x" in (x - 3)² + 1

(6 - 3)² + 1

We now evaluate the expression using PEMDAS

Parenthesis

Exponents

Multiplication and division ( from left to right )

Addition and subtraction ( from left to right )

Step 1: parenthesis

6 - 3 = 3

We would then have (3)² + 1

step 2: exponents

3²=9

we would then have 9 + 1 which = 10

Hence, the answer is C

What is the domain of the absolute value function below?

Answers

Answer: D on Edge.

Step-by-step explanation:

The domain of the absolute value function is (-∞, +∞).

Here,

In the given figure,

The line of the absolute value function extend in both direction of the

x- axis.

We have to find the domain of the absolute value function which shown in graph.

What is Domain?

The Domain is the set of all x-values. It is the horizontal line In a Cartesian Plane.

Now,

In the given figure,

The line of the absolute value function extend in both direction of the

x- axis.

This shows that, the function can take any of the x values as its input.

That's mean all the real number.

Hence, The domain of the absolute value function is (-∞, +∞).

Option 4 is true.

On the first day it was posted online, a music video got 250 views. The number of views that the video got each day increased by 16% per day. How many total views did the video get over the course of the first 12 days, to the nearest whole number?

Answers

Using an exponential function, it is found that the video got 8,314 total views over the course of the first 12 days.

What is an exponential function?

An increasing exponential function is modeled by:

[tex]A(t) = A(0)(1 + r)^t[/tex]

In which:

A(0) is the initial value.r is the growtn rate, as a decimal.

On the first day it was posted online, a music video got 250 views, and the number increased by 16% a day, hence the A(0) = 250, r = 0.16, and the equation is given by:

[tex]A(t) = 250(1.16)^t[/tex]

The total amount over the first 12 days is given by:

[tex]T = \int_{0}^{12} A(t) dt[/tex]

[tex]T = \int_{0}^{12} 250(1.16)^t dt[/tex]

[tex]T = 250\frac{(1.16)^t}{\ln{1.16}}|_{t = 0}^{t = 12}[/tex]

Applying the Fundamental Theorem of Calculus:

[tex]T = 250\frac{(1.16)^{12}}{\ln{1.16}} - 250\frac{(1.16)^0}{\ln{1.16}}[/tex]

T = 8314.

The video got 8,314 total views over the course of the first 12 days.

An equation can be stated as a mathematical statement that is made up of two expressions connected by an equal sign. In its normal form in algebra, it can be said as of an equation is a mathematical statement that shows that two mathematical expressions are equal.

here, we have,

Mark spent a total of $16.35 to buy a total of 11 bags of carrots and bags of tomatoes.

Each bag of carrots costs $1.05, and each bag of tomatoes costs $1.65.

let, he bought x bags of carrots and y bags of tomatoes.

now, we get,

x+y = 11 ....(1)

1.05x + 1.65y = 16.35 ....(2)

solving this, we get,

x= 3

y= 8

Hence, The solution is, he bought 3 bags of carrots and 8 bags of tomatoes.

Find the angle made by the x axis and the terminal side resulting from connecting the origin to (5,7), rounded to the nearest integer

Answers

Answer:

55°

Step-by-step explanation:

To solve this, follow these steps:

i. Make a sketch of the problem.

The sketch has been attached to this response.

ii. Label the sketch properly

As shown in the sketch, θ is the angle between the x-axis and the terminal side resulting from connecting the origin to (5,7).

iii. Solve using the tangent trigonometric ratio

With the proper sketch and labelling, a right triangle is formed with the adjacent and opposite sides to the angle being 5 units and 7 units respectively.

Using the tangent formula,

tan θ = opposite / adjacent

tan θ = 7 / 5

θ = tan⁻¹ (7/5)

θ = tan⁻¹ (1.4)

θ = 54.46

θ = 55° to the nearest integer.

Therefore, the angle made by the x axis and the terminal side resulting from connecting the origin to (5,7), rounded to the nearest integer is 55°
