Step-by-step explanation:

Answer:

a^2

Step-by-step explanation:

a^5  / a^3

We know that x^y / x^z = x^ ( y-x)

a^ ( 5-3) = a^ 2

Answer:

a squared OR a2 OR a^2

Step-by-step explanation:

So we need to remember that numbers and exponents are different. When we divide a5 by a3, we subtract 3 from 5. That gives us 2. So the exponent is 2 and the answer is a2. I hope this helped! :)

Answer:

A

Step-by-step explanation:

We are given the function g(x) = -2x +5

If we need an output of -5, then:

-5 = -2x + 5

-10 = -2x

x = 5

A

Answer:

a. 5

Step-by-step explanation:

We can solve this by simply guessing and checking; plugging in each answer until we get -5.

a) -2(5) + 5

-10 + 5

-5

We can also set the function equal to -5 and solve for x.

-2x + 5 = -5

-2x = -10

x = 5

Answer:

d = 9

Step-by-step explanation:

solving for d

let's get ride of the fraction first so multiple the whole thing by 3

3= 1d - 6

add 6 to both sides

9 = d

easy peasy.

Answer:

D

Step-by-step explanation:

The degree of a polynomial is determined by the largest exponent of a term within the polynomial.

Given

7x³ + 4x - 5 + 8[tex]x^{5}[/tex]

The term with the largest exponent is 8[tex]x^{5}[/tex] with exponent 5

Thus the polynomial is of degree 5 → D

Answer:

B) soda: $0.80 pretzels: $1.20

Step-by-step explanation:

system of equations:

3s+2p=4.80

1s+1p=2.00

solve:

-2(1s+1p=2.00) = -2s-2p=-4.00

3s+2p=4.80

-2s-2p=-4.00

1s=0.80

3(0.80)+2p=4.80

2.40+2p=4.80

2p=2.40

p=1.20

Answer:

The ball reaches maximum height in 3 seconds.

The maximum height of the ball is of 400 feet.

Step-by-step explanation:

Vertex of a quadratic function:

Suppose we have a quadratic function in the following format:

[tex]f(x) = ax^{2} + bx + c[/tex]

It's vertex is the point [tex](x_{v}, f(x_{v})[/tex]

In which

[tex]x_{v} = -\frac{b}{2a}[/tex]

If a<0, the vertex is a maximum point, that is, the maximum value happens at [tex]x_{v}[/tex], and it's value is [tex]f(x_{v})[/tex]

In this question:

The height is modeled by:

[tex]s(t) = -16t^2 + 96t + 256[/tex]

So, the coefficients are:

[tex]a = -16, b = 96, c = 256[/tex]

Instant of time the ball reaches maximum height:

[tex]t_{v} = -\frac{96}{2(-16)} = -\frac{96}{-32} = 3[/tex]

The ball reaches maximum height in 3 seconds.

What is the maximum height of the ball?

This is s(3).

[tex]s(3) = -16t^2 + 96t + 256 = -16*3^2 + 96*3 + 256 = 400[/tex]

The maximum height of the ball is of 400 feet.

Answer:

14+2i

Step-by-step explanation:

That's what the equation is when u simplify it.

Answer:

The answer is

[tex] \frac{ {x}^{2} - n}{m} = { (\frac{ {a}^{2} }{b}) }^{a} \\ {x}^{2} - n = m{( \frac{ {a}^{2} }{b} })^{a} \\ {x}^{2} = m {( \frac{ {a}^{2} }{b} )}^{a} + n \\ x = \sqrt{m {( \frac{ {a}^{2} }{b}) }^{4} - n} [/tex]

Answer:

y =9

Step-by-step explanation:

you know the distance is 10 and some of the x,y points. so start filling what you know into the distance formula

10= √((9-1)^2 + (y-3)^2 )

square both sides to get ride of the square root

100 = 64 + (y-3)^2

36 = (y-3)^2

6 = y-3

y = 9

double check by using 9 for Y and you'll see it works.

The mathematical expression for the verbal expression is the sum of two and four and six times eight will be (2+4+6)8.

Expression in maths is defined as the collection of numbers variables and functions by using signs like addition, subtraction, multiplication, and division.

Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.

Given verbal expression is the sum of two and four and six times eight will be written as:-

Add 2,4, and 6 apply parenthesis, and then multiply by 8. The expression will be:-

E = ( 2 +  4 + 6 ) 8

Therefore, the mathematical expression for the verbal expression is the sum of two and four, and six times eight will be (2+4+6)8.

x = 17

Step-by-step explanation:

Assuming you require to find x

4x - 3 and 115 are same- side interior angles and supplementary, sum to 180°

4x - 3 + 115 = 180

4x + 112 = 180 ( subtract 112 from both sides )

4x = 68 ( divide both sides by 4 )

Answer:

x = 19.06 feet

Step-by-step explanation:

Given that,

The length of a tree, h = 16 feet

It casts a shadow which forms an angle of 40° with the ground.

We need to find the length of the shadow. We can find it using trigonometry such that x be the length of the shadow. So,

[tex]\tan\theta=\dfrac{h}{x}\\\\x=\dfrac{h}{\tan\theta}\\\\x=\dfrac{16}{\tan(40)}\\\\x=19.06\ \text{feet}[/tex]

So, the length of the shadow is 19.06 feet.

Answer:

The whole slices of the cakes of Luke, Kira and Ali are 6, 9 and 12 respectively. So it is possible.

Step-by-step explanation:

It's possible because they cut cakes into different number of slices.

You know that Luke, Kira and Ali each served [tex]\frac{2}{3}[/tex] of their own cake and Luke served 4 slices, Kira served 6 slices and Ali served 8 slices.

Being x the whole slices of cake, and if Luke served [tex]\frac{2}{3}[/tex] of his cake, which are 4 slices, the whole slices of cake of Luke is:

[tex]\frac{2}{3}*x=4 slices[/tex]

Solving:

x= 4 ÷[tex]\frac{2}{3}[/tex]

x= 6

Then, whole slices of Luke's cake is 6.

Performing the same approach for Kira you get:

[tex]\frac{2}{3}*x=6 slices[/tex]

x= 6 ÷[tex]\frac{2}{3}[/tex]

x= 9

Then, whole slices of Kira's cake is 9.

Finally, performing the same approach for Ali you get:

[tex]\frac{2}{3}*x=8 slices[/tex]

x= 8 ÷[tex]\frac{2}{3}[/tex]

x= 12

Then, whole slices of Ali's cake is 12.

The whole slices of the cakes of Luke, Kira and Ali are 6, 9 and 12 respectively. So it is possible.
