Answer:

A) x=5

The sideways line is always x, and the line going up is y, so since the line is only touching the x-intercept you just count where the line is, so x=5

Given that, 1 to the power of 3

Generally, the rules for exponentiation states that if l is any real number and m is a positive integer, then lm can be shown as:

lm = l × l × … × l (m times)

Hence, 1 to the power of 3 can be written as 13, where the number 1 is called the base, and 3 is the power or exponent of the expression.

Therefore, 13 = 1 × 1 × 1 = 1

Hence, 1 to the power of 3 comes as 1.

The quadratic equation 4x² +16x - 4.25 = 0 can be used to determine the thickness of the frame option third is correct.

Any equation of the form [tex]\rm ax^2+bx+c=0[/tex] Where x is variable and a, b, and c are any real numbers where a ≠ 0 is called a quadratic equation.

We have:

The mirror and frame must have an area of 19.25 square feet. The mirror is 3 feet wide and 5 feet long.

Let's suppose the thickness of the frame is x:

Then, the area of the rectangle:

(2x+3)(2x+5) = 19.25

4x² + 10x + 6x + 15 = 19.25

4x² +16x - 4.25 = 0

Thus, the quadratic equation 4x² +16x - 4.25 = 0 can be used to determine the thickness of the frame option third is correct.

Answer:

SA = 105 in^2

Step-by-step explanation:

To find surface area, find the area of all the shapes and add it all together. This shape has 4 triangle faces. They are all the same. So we can find one of them and times by 4.

Area of a triangle:

A = 1/2b•h

= 1/2• 5 • 8

= 1/2 • 40

= 20

One triangle has area 20, so times by 4 (bc four triangles)

4•20

= 80

Area of square 5•5

= 25

Add the areas:

80 + 25

= 105 sq in

1/3πr²h - 2/3πr³

1/3 x π × 64 x (√20² - 8²) - 2/3 x π x (4)³

64π/3 (√336 - 2 x 2/3)

64π (18.33 - 1.33)

64π × 17

201.06 x 17

3418.02 cm²

Work Shown:

16 > i - 4

16+4 > i-4+4

20 > i

i < 20

In the second step, I added 4 to both sides to undo the -4

In the last step, I swapped both sides and I flipped the inequality sign.

If you want to graph this on a number line, then plot an open hole at 20. Then shade to the left to represent all the values smaller than 20.

Answer:

1) The smaller t is -6

The larger t is 7

2) The vertex of the parabola is (1/2, -42.25)

Step-by-step explanation:

Hey there!

To find the zeros of a function, you need to find two values that add up to "b" and multiply together to get "ac"

The b and ac come from the standard form of a parabola which this statement is given to us right now

t^2-t-42

1 is the "a" value, -1 is the "b" value, and -42 is the "c" value

What are two numbers that multiply together and get -42 and those same two numbers add up to -1

Those two numbers are -7 and 6

When you multiply those numbers together, you get -24

And when you add them together, you get -1

Now you can split the -t in the equation

The new equation after splitting the original equation will look like this

t^2-7t+6t-42

Now we group the equation into two parts

(t^2-7t) + (6t-42)

Since t is the common variable in the first set of parentheses, we can take it out

t(t-7)+(6t-42)

Now in the second pair of parentheses, 6 is the constant term

You can also take that out

t(t-7)+6(t-7)

Now we have our zero pairs

We take one of the parentheses and the terms that are outside of the parentheses

Now we have

(t+6)(t-7)=0

Now we can find our two zeros

The smaller t is -6

The larger t is 7

Now we have to find the vertex

The formula to solving the x-coordinate of the vertex is -b/2a

The "b: value is -1 and the "a" value is 1

So, the x-coordinate of the vertex is 1/2

Now we plug that into the equation

(1/2)^2 - 1/2 - 42

1/4 - 1/2 - 42

-1/4 - 42

-169/4 --> -42.25

So, the y-coordinate of the vertex s -42.25

This means,

The vertex of the parabola is (1/2, -42.25)

Step-by-step explanation:

since this answer wants an approximation,  we can round the  cost up

Ham- 6                                 1/2 of 6 = 3

Turkey- 5                             1 pound of turkey= 5

Roast Beef- 7                       1/4 of 7= 1.75

Salami- 3                              2 x 3= 6   1/2 of 3= 1.5 = 7.5

bologna- 4                            No bologna was purchased.

3+5+1.75+ 7.5= 17.25 which is approximately 17.  

The polynomial f(x)= -x³ - 7x² - 7x + 15 has zeros located at -5, -3, 1 because f(-5) = f(-3) = f(1) = 0

An equation is an expression that shows the relationship between two or more numbers and variables.

The function f(x)= -x³ - 7x² - 7x + 15 has zeros located at -5, -3, 1, hence:

f(-5) = -(-5)³ - 7(-5)² - 7(-5) + 15 = 0

f(-3) = -(-3)³ - 7(-3)² - 7(-3) + 15 = 0

f(1) = -(1)³ - 7(1)² - 7(1) + 15 = 0

The polynomial f(x)= -x³ - 7x² - 7x + 15 has zeros located at -5, -3, 1 because f(-5) = f(-3) = f(1) = 0
