scoray [572]

Answer:

The corresponding point is (1,-4)

Step-by-step explanation:

we know that

The point (1,-8) is on the graph of f(x)

so

that means

For x=1, f(1)=-8

therefore

For the function 1/2f(x)

For x=1, 1/2f(1)=-8/2=-4

ozzi

Answer:

<h2><u><em>16 cm </em></u></h2>

Step-by-step explanation:

The volume of a cube can be found using the equation V=s^3 where s represents the length of the sides of the cube. if a cube has volume 4096 cubic centimeters, what is the length of each side of the cube?

you use the inverse formula

s = ∛V

s = ∛4096

s = 16 cm

-------------------------

check

16 × 16 × 16 = 4096 cm³

The answer is good

Jenna spends $15.04 at the store on notebooks and folders for school. Notebooks cost $4.85 each, and folders cost $0.89 each. Sh
cluponka [151]

Answer:

\boxed{\text{2 notebooks and 6 folders}}

Step-by-step explanation:

Let n = number of notebooks

and f = number of fodders

You have a system of two equations:

\begin{cases}(1)& 4.85n + 0.89f = 15.04\\(2) & n+ f = 8\end{cases}\\\\

\begin{array}{lrcll}(3) & f & = & 8-n &\text{Subtracted n from each side of (2)}\\& 4.85n+0.89(8-n) & = & 15.04 &\text{Substituted (3) into (1)}\\& 4.85n+7.12-0.89n & = & 15.04 &\text{Distributed 0.89}\\& 3.96n+7.12 & = & 15.04 &\text{Combined like terms} \\& 3.96n & = & 7.92 & \text{Subtracted 7.12 from each side} \\(4) & n & = & 2 & \text{Divided each side by 3.96}\\& 2+ f & = & 8 & \text{Substituted (4) into (2)}\\& f & = & 6 &\text{Subtracted 2 from each side} \\\end{array}

Jenna bought \boxed{\textbf{two notebooks and six folders} }.

Check:

\begin{array}{rclcrcl}4.85\times2+0.89\times6 & =& 15.04 & \qquad &2+6&=&8\\9.70+5.34 & = & 15.04 & \qquad &8&=&8\\15.04& = & 15.04 & & & & \\\end{array}

OK.

Claire has a hot tub with a diameter of 7 feet. She wants to purchase a cover to protect the hot tub. What is the area
harkovskaia [24]

Answer:

The area  of the cover for the hot tub must be:

  • <u>38 square feet</u>.

Step-by-step explanation:

First, you must understand that since a hydromassage tub is mentioned and the diameter, it is assimilated that it is round in its upper part, which is why the formula is used to find the area of a circle:

  • <u>Area of a circle = pi * radius ^ 2</u> (you must know that the radius is half the diameter)

Since the diameter is mentioned, it can be replaced in the formula:

  • Area of a circle = 3.14 * (3.5 feet) ^ 2
  • <u>Area of a circle = 38,465 square feet. Approximately 38 square feet</u>.
