The second option is the correct answer

[tex]16x^{4}+40x^{3} -24x^{2}[/tex]

The expression given to us is:

[tex]8x^{2} (5x+2x^{2}-3 )[/tex]

Herein, we can simplify it by opening up the bracket and multiplying each term inside the bracket by the term which is outside the bracket.

Thus, we get:

[tex]8x^{2} (5x+2x^{2}-3 )=8*5x^{2+1} +8*2x^{2+2}-8*3x^{2}[/tex]

[tex]40x^{3} +16x^{4}-24x^{2}[/tex]

Rearranging the above expression in descending order of power we get:

Answer:

simple interest

Step-by-step explanation:

this is because r is interest rate, p is principal, and t is time

Answer:

simple interest

Step-by-step explanation:

Simple interest rate is defined as: I = p * r * t. So you're taking the principle amount (initial amount loaned) and multiply it by the interest rate. This gives you the interest rate in a year (usually, depends on time unit of t). Generally speaking, it gives you the interest over a specific amount of time. Now multiply it by the amount of time that's passed. So you're just calculating the total amount of interest. So the I stands for the simple interest.

Inequalities help us to compare two unequal expressions. The inequality that represents the given statement is 45≤x≤ 65.

Inequalities help us to compare two unequal expressions. Also, it helps us to compare the non-equal expressions so that an equation can be formed.

It is mostly denoted by the symbol <, >, ≤, and ≥.

Given the maximum legal speed on the highway is 65 MPH, therefore, the value of x must not exceed 65 MPH.

x ≤ 65

Also, the minimum legal speed on the highway is 45 MPH, therefore, the value of x must not be less than 45 MPH.

45≤x

By combining the two inequalities, we will get,

45≤x≤ 65

Hence, the inequality that represents the given statement is 45≤x≤ 65.

Answer:

$30.60

Step-by-step explanation:

So when a problem says some price is x% off, it means the current price is now (100-x)% of the original value. So if the shirt is 15% off, the current price is 85% the original value. To find 85% of a number you simple convert the percentage into a decimal, by dividing it by 100 and multiply that decimal by the value. So in this case 85/100 = 0.85. And then 0.85 * 45 = 38.25. Now that it reduces its price by 20%, it's 80% the original value. 38.25 * 0.8 = 30.60.

The volume of the octagonal pyramid is 1302 cubic m if the length of the apothem is 7 m.

The pyramid has an octagonal base with 8 isosceles triangular faces, known as an octagonal base pyramid.

The length of the apothem = 7 m

Side length = 9 m

The area of the one triangle = (1/2)×7×9 = 63/2 square m

The area of the octagonal base = 8(63/2) = 252 square m

The volume of the pyramid = (1/3)(base area)(height)

The volume of the pyramid = (1/3)(252)(15.5)

= 1302 cuibc m

Thus, the volume of the octagonal pyramid is 1302 cubic m if the length of the apothem is 7 m.

Answer:

Two solutions exist for the system of equations in the graph.

Step-by-step explanation:

Solutions are when the two graphs intersect.

The equation of a parabola that has intercepts of x=-2 and x=6 and passes through point (8,6) is f(x) = 3/10(x+2)(x-6)

The standard equation of a parabola is in the form f(x) = (x-a)(x-b)

where a and b are the intercepts of the graph. Given the parabola that has intercepts of x=-2 and x=6, the resulting equation will be:

f(x) = a(x-(-2))(x-6)

f(x) = a(x+2)(x-6)

If the parabola passes through (8, 6), then;

6 = a(8+2)(8-6)

6 = a(20)

a = 6/20

a = 3/10

Substitute

f(x) = 3/10(x+2)(x-6)

Hence the equation of a parabola that has intercepts of x=-2 and x=6 and passes through point (8,6) is f(x) = 3/10(x+2)(x-6)

Answer:

g(f(-2)) = -15

Step-by-step explanation:

• f(x) = x³

Then

f(-2) = (-2)³ = -8

• When x = -2 → g(f(x)) = g(f(-2)) = g(-8)

Since -8 ≤ 0 then g(-8) = 2×(-8) + 1 = -16 + 1 = -15

Conclusion:

g(f(-2)) = -15

Answer:

x = 0 or x = 1

Step-by-step explanation:

f(x) = |x| - 4

g(x) = x³ - 4

f(x) = g(x)

|x| - 4 = x³ - 4

Add 4 to both sides.

|x| = x³

x = x³  or  -x = x³

x³ - x = 0   or   x³ + x = 0

x(x² - 1) =   or  x(x² + 1) = 0

x = 0 or x + 1 = 0 or x - 1 = 0

x = 0 or x = -1 or x = 1

x = -1 does not work, so we discard that solution.

Answer: x = 0 or x = 1

Answer:

values of x: x = 1 and x = 0

Step-by-step explanation:

Given:

Want: x - values when f(x) = g(x)

|x| - 4 = x³ - 4, the 4 cancel out on both sides

|x| = x³

|x| - x³ = x³ - x³

|x| - x³ = 0, x ≥ 0

-x - x³ = 0, x < 0

x = 0

x = -1, x ≥ 0

The perimeter of the triangle is 30 units

The vertices are (−7,−1), (5,−1), and (5,4).

Start by calculating the distance between the vertices using:

[tex]d = \sqrt{(x_2 -x_1)^2 + (y_2 -y_1)^2[/tex]

So, we have:

[tex]d1 = \sqrt{(-1 + 1)^2 + (5 + 7)^2[/tex]

d1 = 12

[tex]d2 = \sqrt{(-1 - 4)^2 + (5 - 5)^2[/tex]

d2 =5

[tex]d3 = \sqrt{(-1 - 4)^2 + (-7 - 5)^2[/tex]

d3 = 13

The perimeter is then calculated as:

P = d1 + d2 + d3

This gives

P = 12 + 5 + 13

Answer: A

Step-by-step explanation:

This is a fact.

The absolute value parent or modulus function is f ( x ) = | x |

Regardless of the sign, a modulus function returns the magnitude of a number. The absolute value function is another name for it.

It always gives a non-negative value of any number or variable. Modulus function is denoted as y = |x| or f(x) = |x|, where f: R → (0,∞) and x ∈ R.

The value of the modulus function is always non-negative. If f(x) is a modulus function , then we have:

If x is positive, then f(x) = x

If x = 0, then f(x) = 0

If x < 0, then f(x) = -x

Given data ,

Let the function be represented as f ( x )

Now , the value of f ( x ) is

f ( x ) = | x |

The absolute value parent function is f(x) = |x|, which represents the absolute value of x.

Option B, f(x) = 13x1, does not represent the absolute value function, as it has a coefficient of 13, which scales the function vertically.

Option C, f(x) = x-− 1|, represents a translation of the absolute value function. The "-1" shifts the function one unit to the right, and the vertical bar denotes the absolute value of the expression within the bar. While it is related to the absolute value function, it is not the parent function itself.

Option D, f(x) = x+2, represents a linear function with a slope of 1, which is not the absolute value function.

Hence , the absolute value parent function is f ( x ) = | x |

Answer:

You need to know what 3 u - 9 is equal to, in order to solve the equation for the variable u. Please post the entire equation. As this stands, it is just an algebraic expression and cannot be "solved".

Step-by-step explanation:

Using the trigonometric ratios, the measures are:

a. z = 222.5 ft

b. h = 38.6 ft.

c. b = 10.4 ft

d. B = 219.1 ft.

The ratios of trigonometry that can be used to solve a right triangle are:

sin ∅ = opp/hyp

cos ∅ = adj/hyp

tan ∅ = opp/adj.

a. Find h using the sin ∅ = opp/hyp:

sin 75 = opp/hyp = h/40

h = (sin 75)(40) = 38.6

Find z using the sin ∅ = opp/hyp

sin 10 = opp/hyp = 38.6/z

z = 38.6/sin 10

z = 222.5 ft. (length of the zip line)

b. Height of the tree = h = 38.6 ft.

c. Using sin ∅ = opp/hyp, find b (distance between the base of the ladder and the base of the tree):

sin 15 = b/40

b = (sin 15)(40)

b = 10.4 ft

d. Using sin ∅ = opp/hyp, find B as shown in the image:

sin 80 = opp/hyp = B/222.5

B = (sin 80)(222.5)

B = 219.1 ft.

Step-by-step explanation:

1) required area can be calculated as four area of the triangle PQT:

A=4*A(ΔPQT);

2) A(ΔPQT)=0.5*PT*QT, then

3) A=4*0.5*PT*QT; ⇔

A=2*PT*QT; ⇒

4) finally,

A=2*11*9=198 [m²].

The area of the rhombus PQRS is 198 m².

A rhombus is a quadrilateral with four vertices, four sides and four angles with all four sides are equal. It has basically a diamond shape. Rhombus will become square if all the angles of the rhombus equals 90°.

Given that, PT = 11 m and QT = 9 m.

We know that diagonals of a rhombus are perpendicular bisectors.

Therefore, RT = 11 m and ST = 9 m.

Area of a rhombus can be found using diagonals as,

Area = [tex]\frac{1}{2}[/tex] × D₁ × D₂

where D₁ and D₂ are the length of two diagonals of the rhombus.

D₁ = PT + RT = 11 + 11 = 22 m

D₂ = QT + ST = 9 + 9 = 18 m

Area = [tex]\frac{1}{2}[/tex] × 22 × 18

        = 22 × 9
