Answer: 7 and 8

Step-by-step explanation:

Square root and squared cancel out

Answer:

a=7

b=32

Step-by-step explanation:

The first one (a) is 7 because if you square a square root, you get the number inside the root. Also, technically a square root has an exponent of (1/2) so when you have a power-to-a-power (power rule of exponents) you multiply the exponents. So ([tex]7^{1/2}[/tex])^2 is 7.

For (b) you have to take it in two parts. Square the square root and you get 2. Square the 4 in front, you get 16. Multiply those two numbers (16 and 2) together and you get 32.

Edit: Check on your calculator, you get the same answers I got! :)

Answer:

g(1)

Step-by-step explanation:

The y intersect is 2

y=x+2

Answer:

The rate of g(x) is 1

Step-by-step explanation:

Rate could also mean the slope.

Get two points from the graph:

(0,2) and (2,4)

m = (Y_2 - Y_1)/(X_2-X_1)

m = (4-2)/(2-0)

m = 2/2

m = 1

Step-by-step explanation:

for first,

then solving this we get

5) The height of a rocket after it is launched

For this case, what you should do is remember the kinematics expressions where we have:

a

v = a * t + vo

y = a * t ^ 2 + vo * t + i

Where,

a: acceleration

v: speed

y: vertical position

t: time

vo: initial speed

yo: initial position

We observe that the expression for the given position is given by a quadratic expression.

Step-by-step explanation:

Let's first simplify all terms, then convert them to /10:

42/12 = 7/2 = 35/10

85/25 = 17/5 = 34/10

117/30 = 39/10

Then the final addition is:

(35-34+39)/10 = 40/10 = 4

Step-by-step explanation:

a : (-6 , -8)

b: (6 , 8)

I used desmos for the problems

Answer:

150%

Step-by-step explanation:

this is because you can make a part to whole ratio where you have x/100 (which would symbolize the percent) and 160/40 (which would symbolize the part) then, multiply 160 by 100 to get 16000 and then divide by 40 to fulfill the x. Hope this helps!

Answer:

Non-linear

Step-by-step explanation:

This equation represents a reciprocal function.

You can't divide by zero so it never passes the y-axis, therefore it cannot be linear.

The graph of this equation is attached below.

I hope this helps!!

Non-linear. In linear equations, you don't divide a number by x.

Answer:

Following are the solution to the given points:

Step-by-step explanation:

In point a:

The middle point of the segment AB will be the hypothesis, which is equal to M.

In point b:

The conclusion of AB = 2AM.  

In point c:

If p q is incorrect, after all, M is not really the middle point of a section AB, then the inference is wrong.

Answer: 4,4

Step-by-step explanation:

because just listen to me ;)

The linear regression equation that represents this set of data is Y = -12.41 + 1.15x and the projected test  grade for a student with a homework grade of 49 is 44 and this can be determined by using the generalized equation of regression.

Given :

The generalized regression equation is given below:

Y = a + bX   --- (1)

where b is given by the formula:

[tex]\rm b = \dfrac{N\sum XY-\sum X \sum Y}{N\sum X^2-(\sum X)^2}[/tex]

Now, substitute the values of the known terms in the above formula in order to determine the value of 'b'.

b = 1.15

and the formula of a is given below:

[tex]\rm a = \dfrac{\sum Y - b \sum X}{N}[/tex]

Now, substitute the values of the known terms in the above formula in order to determine the value of 'a'.

a = -12.41

Now, substitute the values of a and b in the equation (1).

Y = -12.41 + 1.15x

Now, at x = 49 the value of Y becomes:

Y = -12.41 + 1.15(49)

Y = 43.94

Y [tex]\approx[/tex] 44

Answer:

1.) 6 football tickets for $24

Step-by-step explanation:

The situation which leads to a unit cost of $6 per football ticket is; 6 football tickets for $24.

The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value. Multiplication is the mathematical operation is used to determine the product of two or more numbers.

We have been given a condition as; a unit cost of $6 per football ticket.

Meaning that;

The cost of one football ticket is 6 dollar

Then The cost of 12 football ticket  = 12 x 6 dollar

                                                  = 72

Therefore, the situation which leads to a unit cost of $6 per football ticket is; 12 football tickets for $72.

Answer:

Please check the explanation.

Step-by-step explanation:

Given the expression

[tex]V=\sqrt[3]{x-1}+3[/tex]

Determining the domain:

We know that the domain of a function is the set of input values for which the function is defined.

From the given graph, it is clear that the function has no undefined points nor domain constraints.

Therefore, the domain is:

In other words:

[tex]\mathrm{Domain\:of\:}\:\sqrt[3]{x-1}+3\::\quad \begin{bmatrix}\mathrm{Solution:}\:&\:-\infty \:<x<\infty \\ \:\mathrm{Interval\:Notation:}&\:\left(-\infty \:,\:\infty \:\right)\end{bmatrix}[/tex]

Determining the range:

We know that the range of a function is the set of values of the dependent variable for which a function is defined.

It is clear from the graph that the range can be any real number.

i.e. the range is:

{y|y is a real number}

In other words,

[tex]\mathrm{Range\:of\:}\sqrt[3]{x-1}+3:\quad \begin{bmatrix}\mathrm{Solution:}\:&\:-\infty \:<f\left(x\right)<\infty \\ \:\mathrm{Interval\:Notation:}&\:\left(-\infty \:,\:\infty \:\right)\end{bmatrix}[/tex]

Answer:

With the discounts, you saved a total of $4.90. You still owe $29.10.

Step-by-step explanation:

Shoes:

10% of 24 is 2.4

The shoes cost 21.60  with the 10% discount and before tax.

Belt:

25% of 10 is 2.5

The belt cost $7.50 with the 25% discount and before tax.

Total:

You still owe 29.10 for the belt and shoes before tax.

You saved $2.4 on the shoes and $2.5 on the belt (total of $4.90)
