Subtract the polynomials.
( x^6 -2x^5 –x^3 — 7) – (3x^6 - 3x^5 -2x^ 2 – 5)

Answer:

f(-4) is basically just saying that you need to use the function given while x = -4.

The function given:

f(x) = -8(5-x)

We see that f(-4) means that x has to be -4, so we can substitute it in:

f(-4) = -8(5-(-4))

f(-4) = -8(9)

f(-4) = -72

Therefore, f(-4) is -72.

Answer:

It's D I believe because y is the total cost . $2.50 is being added per pound of berries they pick which represents x. Then you add the $3 payed to enter the farm. Hopefully it's righttt :)

======================================================

Work Shown:

A = old value = 75

B = new value = 78

C = percent change

C = [ (B-A)/A ] * 100%

C = [ (78-75)/75 ] * 100%

C = (3/75) * 100%

C = 0.04 * 100%

C = 4%

The positive C value means we have a percent increase.

The price has increased by 4%

hi

Step-by-step explanation:

To round a number to the nearest hundredth , look at the next place value to the right (the thousandths this time). Same deal: If it's 4 or less, just remove all the digits to the right. If it's 5 or greater, add 1 to the digit in the hundredths place, and then remove all the digits to the right.

Answer:

Step-by-step explanation:

let the missing angle be x

take 65 degree as reference angle

use tan rule

tan 65=opposite/adjacent

2.14=x/7

2.14*7=x

14.98=x

The length of the ramp is 6.91 feet

Given data:

To determine the length of the ramp, we can use trigonometry. So, use the sine function, which relates the angle of the ramp to the ratio of the opposite side (length of the ramp) to the hypotenuse (the distance the ramp covers).

Given that the angle of the ramp is 24°, set up the equation:

sin(24°) = opposite/hypotenuse

The opposite side is the length of the ramp and the hypotenuse is the distance it covers, which is 17 feet.

sin(24°) = length of the ramp / 17

To find the length of the ramp, rearrange the equation:

The length of the ramp = sin(24°) * 17

L ≈ 6.91 feet

Hence, the length of the ramp is approximately 6.91 feet.

Answer:

x = 11.25

Step-by-step explanation:

The sum of the angles is 90 degrees since it is a right angle

6x+2x = 90

8x = 90

Divide each side by 8

8x/8 =90/8

x =11.25

Answer: -1.13

Step-by-step explanation: I counted from -1.1 to -1.15

Let's take a look at our table here in order to solve the problem. We need to know what g(0) and g(4) are to be able to solve.

Since we are plugging in x-values and looking for y-values, we simply need to find 0 and 4 on the left side of the table (the x side), and then find their corresponding g(x), or y, values.

g(0) = -5

g(4) = -4

Now, all that's left to do is add these two values.

-5 + -4

-9

Hope this helps!! :)

Answer:

- 9

Step-by-step explanation:

g(0) = - 5 ← value of g(x) when x = 0

g(4) = - 4 ← value of g(x) when x = 4

Then

g(0) + g(4) = - 5 + (- 4) = - 5 - 4 = - 9

Answer:

[tex]x\geq 2[/tex]

Step-by-step explanation:

The parent function, [tex]y=\sqrt{x}[/tex], has a domain of [tex]x\geq 0[/tex] or [tex][0, \infty)[/tex], because the value under the radical cannot be less than 0 (we cannot take the square root of a negative number). Thus, by setting everything inside the radical to 0, we can find the domain of this function:

[tex]x-2\geq 0,\\x\geq 2[/tex]

Thus this domain of this function is:

As an inequality: [tex]x\geq 2[/tex] (desired in problem)

In interval notation: [tex][2, \infty)[/tex]

Answer:

[tex]b = \sqrt{\frac{C^{2} }{2(\pi )^{2} } - a^{2}}[/tex]

Step-by-step explanation:

Given - The circumference of the ellipse approximated by [tex]C = 2\pi \sqrt{\frac{a^{2} + b^{2} }{2} }[/tex]where 2a and 2b are the lengths of 2 the axes of the ellipse.

To find - Which equation is the result of solving the formula of the circumference for b ?

Solution -

[tex]C = 2\pi \sqrt{\frac{a^{2} + b^{2} }{2} }\\\frac{C}{2\pi } = \sqrt{\frac{a^{2} + b^{2} }{2} }[/tex]

Squaring Both sides, we get

[tex][\frac{C}{2\pi }]^{2} = [\sqrt{\frac{a^{2} + b^{2} }{2} }]^{2} \\\frac{C^{2} }{(2\pi)^{2} } = {\frac{a^{2} + b^{2} }{2} }\\2\frac{C^{2} }{4(\pi)^{2} } = {{a^{2} + b^{2} }[/tex]

[tex]\frac{C^{2} }{2(\pi )^{2} } = a^{2} + b^{2} \\\frac{C^{2} }{2(\pi )^{2} } - a^{2} = b^{2} \\\sqrt{\frac{C^{2} }{2(\pi )^{2} } - a^{2}} = b[/tex]

∴ we get

[tex]b = \sqrt{\frac{C^{2} }{2(\pi )^{2} } - a^{2}}[/tex]

→ (√5 + 2√2) + (√2 - 5√3)

Removing the brackets.

→ √5 + 2√2 + √2 - 5√3

→ √5 + (2 + 1)√2 - 5√3

→ √5 + 3√2 - 5√3

Therefore, the required answer is √5 + 3√2 - 5√3.
