Answer:

f(- 4) = 30

Step-by-step explanation:

To evaluate f(- 4) substitute x = - 4 into f(x), that is

f(- 4) = 5(2 - (- 4)) = 5(2 + 4) = 5(6) = 30

ra1l [238]

Answer:

The original selling price would be $ 515.87 ( approx )

Step-by-step explanation:

Consider the complete question is :

"A sporting goods store manager was selling a ski set for a certain price. The manager offered the markdowns​ shown, making the​ one-day sale price of the ski set ​$325. Find the original selling price of the ski set. It was marked down 10% and 30%"

Suppose x be the original selling price ( in dollars ),

After marking down 10%,

New selling price = x - 10% of x = x - 0.1x = 0.9x

Again after marking down 30%,

Final selling price = 0.9x - 30% of 0.9x

= 0.9x - 0.3 × 0.9x

= 0.9x - 0.27x

= 0.63x

According to the question,

0.63x = 325

\implies x =\frac{325}{0.63}=\$ 515.87

Therefore, the original selling price would be $ 515.87.

A square sheet of paper measures 42 centimeters on each side. What is the length of the diagonal of this​ paper?
Illusion [34]
59.4cm
Use Pythagorean theorem to find the diagonal (^ means exponent)
a^2 + b^2 = c^2
42^2 + 42^2= c^2
1764+1764=c^2
3528=c^2
square root both sides
c= 59.39696962
round and you get 59.4 cm

B

Step-by-step explanation:

It is B because to find the volume you multiply all three values together, which gets you 68.448. I multiplied 9.2x3.1, which got me 28.52, and then I multiplied 28.52 by 2.4 which got me 68.448.
