6 0

Answer:

49-7F

Step-by-step explanation:

F(7)+xF=2x+5x

F(7)+xF=7x

F(7)=7x-xF

F(7)=x(7-F)

substitute x=7 in the equation above

Therefore, 7(7-F)

=49-7F

Find the domain in interval notation.
Nady [450]

Answer:

<em>x ∈ ( - ∞ , - 8 ) ∪ ( - 8 , 0 ) ∪ ( 0 , 8 ) ∪ ( 8 , ∞ ) </em>

Step-by-step explanation:

x³ - 64x = x( x² - 64 ) ≠ 0 ⇒ x ≠ 0 and x ≠ ± 8

<em>x ∈ ( - ∞ , - 8 ) ∪ ( - 8 , 0 ) ∪ ( 0 , 8 ) ∪ ( 8 , ∞ )</em>

A rectangle has a length of x inches and a width 2 inches less than the length. If the dimensions were doubled, what would be th
Gelneren [198K]

Answer:

Option (4)

Step-by-step explanation:

Area of a rectangle = Length × width

If the dimensions of the given rectangle is doubled,

Area of the new rectangle = 2(Length) × 2(width)

                                            = 4(Length × width)

                                            = 4(x)(x - 2)

                                            = 4[x² - 2x]

                                            = 4x² - 8x

Therefore, Option (4) will be the correct option.

Find the volume of a right circular cone that has a height of 17.5 ft and a base with a diameter of 6.1 ft. Round your answer to
julia-pushkina [17]
Answer:
volume of cone = 170.5 ft³

Explanation:
The volume of the right circular cone can be calculated as follows:
volume = \frac{1}{3} * \pi *r^2 *h

We are given that:
diameter = 6.1 ft.......> This means that: radius (r) = 6.1 / 2 = 3.05 ft
height (h) = 17.5 ft

Substitute with the givens in the above equation to get the volume as follows:
volume = \frac{1}{3} * \pi *(3.05)^2*17.5

volume = 170.477 which is approximately 170.5 ft³

Hope this helps :)
