[tex] { - 3}^{4} = - (3 \times 3 \times 3 \times 3) \\ {( - 3)}^{4} = ( - 3 \times - 3 \times - 3 \times - 3)[/tex]

The difference is that (-3)^4 has a negative 3 with parenthesis around it, which means that if it was in PEMDAS, you would work that out first.

Answer:

First triangle: [tex]a = 5\sqrt{2}[/tex], second triangle: [tex]c = \frac{8\sqrt{3}}{3}[/tex]

Step-by-step explanation:

In the first triangle, the value of [tex]a[/tex] is equal to the following trigonometric relation:

[tex]a = \frac{5}{\cos 45^{\circ}}[/tex]

[tex]a = \frac{5}{\frac{\sqrt{2}}{2} }[/tex]

[tex]a = \frac{10}{\sqrt{2}}[/tex]

[tex]a = \frac{10\sqrt{2}}{2}[/tex]

[tex]a = 5\sqrt{2}[/tex]

In the second triangle, we obtain the value of [tex]c[/tex] is equal to the following trigonometric relation:

[tex]c = 8\cdot \tan 30^{\circ}[/tex]

[tex]c = 8 \cdot \left(\frac{\sin 30^{\circ}}{\cos 30^{\circ}} \right)[/tex]

[tex]c = 8\cdot \left(\frac{\frac{1}{2} }{\frac{\sqrt{3}}{2} } \right)[/tex]

[tex]c = \frac{8}{\sqrt{3}}[/tex]

[tex]c = \frac{8\sqrt{3}}{3}[/tex]

Hello! answer: 20

Step-by-step explanation:

I don't know why they say z = something there is no z so we dont need that but we do need to know what y and x is so... y = 5 and x = 10

so the 10 + 2 × y = answer

10 + 10 = 20 so 20 is the answer! Hope that helps!

The communitative property is a math rule that says that the order in which we multiply numbers does not change the product.

Answer:

B.   y = 10(2)^x

Step-by-step explanation:

y = ab^x

to find "b" divide the function at x = 3 by the function at x = 2

80 = ab^3

——————

40 = ab^2

This results in

2 = b

to find "a" plug pickany value of x

using x = 2

40 = a(2²)

40 = a(4)

a = 10

With a = 10 and b = 2 the exponential function y = ab^x is

y = 10(2)^x

Answer:

2

Step-by-step explanation:

the gradient = (12-4)/(0+4)=8/4=2

Answer:

gradient = 2

Step-by-step explanation:

Calculate the gradient m using the gradient formula

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = (- 4, 4) and (x₂, y₂ ) = (0, 12)

m = [tex]\frac{12-4}{0+4}[/tex] = [tex]\frac{8}{4}[/tex] = 2

Answer:

Point B reflected = 2, -3

Step-by-step explanation:

Answer:

See explanation.

Step-by-step explanation:

You have to use the inverse operation of -6 to get x by itself. So you have to add 6 to each side to get rid of the -6. And -12+6=-6. So, x=6.

Answer:

X is -6

Step-by-step explanation:

You have to add 6 to both sides like -6+6 and -12+6

-12+6=-6 which is the answer because -6-6 is -12

Step-by-step explanation:

Answer: D trust me it is 100

Step-by-step explanation:

The maximum area the goat can graze is 100Tt ft2​, the correct option is D.

Given

A goat is tethered to a rope that is 10 ft. long.

The area of the circle is equal to the pie times of the square of the radius of the circle.

The maximum area that the goat can graze in the area of the circle that can be formed due to its circular movement.

The length of the rope represents the radius of the circle, so that;

[tex]\rm Area \ the \ goat \ can \ graze =r^2 \times Tt\\\\ Area \ the \ goat \ can \ graze =(10)2 \times Tt\\\\Area \ the \ goat \ can \ graze =100 \ Tt\\[/tex]

Hence, the maximum area the goat can graze is 100Tt ft2​.

Answer:

(x + 4)(5x - 4)

Step-by-step explanation:

[tex]5x^2 + 16x – 16 \\ = 5x^2 + 20x - 4x– 16 \\ = 5x(x + 4) - 4(x + 4) \\ = (x + 4)(5x - 4)[/tex]

Answer:

 (5x - 4) • (x + 4)

Step-by-step explanation:

Multiply the coefficient of the first term by the constant   5 • -16 = -80

Find two factors of  -80  whose sum equals the coefficient of the middle term, which is   16 .

Rewrite the polynomial splitting the middle term using the two factors found in step 2 above,  -4  and  20  

                    5x2 - 4x + 20x - 16

Add up the first 2 terms, pulling out like factors :

                   x • (5x-4)

             Add up the last 2 terms, pulling out common factors :

                   4 • (5x-4)

Add up the four terms of step 4 :

                   (x+4)  •  (5x-4)

            Which is the desired factorization

An expression is defined as a set of numbers, variables, and mathematical operations. The given expression can be written in the form of xⁿ as x⁻⁰°⁶⁶.

In mathematics, an expression is defined as a set of numbers, variables, and mathematical operations formed according to rules dependent on the context.

The given expression  [tex]\dfrac{1}{x^{\frac23}}[/tex] can be written in the form of xⁿ using the exponential property 1/x=x⁻¹. Therefore, the expression can be rewritten as,

[tex]\dfrac{1}{x^{\frac23}}\\\\= x^{-\frac23}[/tex]

= x⁻⁰°⁶⁶

Hence, the given expression can be written in the form of xⁿ as x⁻⁰°⁶⁶.
