Answer: 8 more questions.

Step-by-step explanation:

He has already answered 6 questions worth 5 points so 6 x 5 = 30

Subtract 30 from 70 : 70 - 30 = 40

He needs 40 more points to get the desired score.

40 ÷ 5 = 8

So he needs to answer 8 more questions, each worth 5 points to get the desired score.

The degree of the polynomial function f(x) is 4.

Lyrx [107]

Answer:

Option A

Step-by-step explanation:

Degree of the polynomial function = 4

That means highest degree term of the given polynomial has power = 4

If the roots of a quadratic polynomial are a, b, c, d then the polynomial function will be,

f(x) = (x - a)(x - b)(x - c)(x - d)

It's given in the question that roots are x = -2, -1, 1 and 3

Therefore, polynomial function will be,

f(x) = (x + 2)(x + 1)(x - 1)(x - 3)

From the given options, graph A shows that the graph intersects the x-axis at x = -2, -1, 1 and 3

Therefore, Option A will be the answer.

Sandra has a cylindrical mold for making candles with a radius of 3.4 cm and a height of 6 cm. If Sandra uses a rectangular bloc

Wittaler [7]

Answer:

$14\ candles$

Step-by-step explanation:

step 1

Find the volume of the cylindrical mold

The volume is equal to

$V=\pi r^{2} h$

we have

$r=3.4\ cm$

$h=6\ cm$

assume

$\pi=3.14$

substitute

$V=(3.14)(3.4)^{2}(6)$

$V=217.79\ cm^{3}$

step 2

Find the volume of the wax

The volume is equal to

$V=(15)(12)(18)$

$V=3,240\ cm^{3}$

step 3

Divide the volume of the wax by the volume of the cylindrical mold, to calculate the number of candles

$3,240/217.79=14.9\ candles$

Round down

$14\ candles$
