Answer:

option D is correct.

Step-by-step explanation:

The real number y=a is the root of the polynomial f(y) if and only if

f(a) =0

So, when we see a graph of the polynomial, the x-intercepts are the real roots of the graph f(y)

We can find x-intercept of graph, by looking at the graph and finding out points that touch the x-axis on the graph.

In the graph given the points -6 and 2 touch the x-axis of the graph, So these are the real roots of the graph.

So, option D is correct.

Gennadij [26K]

Answer:

So if 14% are over 65, and 320 residents are over 65, then we can say that 14% of the town is 320. Then, we can divide by 14 to find 1%, which is 22.857142857 Now we can multiply this by 100 to get 2285.7142857.

ASHA 777 [7]

Answer:

No, the cone will not hold all of the ice cream.

Step-by-step explanation:

Given:

" According to the Joy Cone Company, their waffle cones have a diameter of 2 5/8 inches and a height of 6 inches.

If you place one scoops of ice cream (in the shape of a sphere) with a diameter of 2 7/8 inches would let it melt.

Now, to explain mathematically will the cone hold all of the ice cream.

Taking the value of π = 3.14.

So, to get the volume of waffle cone we put formula:

Height (h) = 6 inches.

Diameter = $2\frac{5}{8}=\frac{21}{8}\ inches.$

Thus radius (r) = Diameter ÷ 2 = $\frac{\frac{21}{8}}{2} =\frac{21}{16} \ inches.$

$Volume=\pi r^2\frac{h}{3}$

$Volume=3.14\times \frac{21}{16} \times \frac{21}{16} \times \frac{6}{3}$

$Volume=3.14\times 1.31\times 1.31\times 2$

$Volume=10.78\ inches^3.$

The volume of waffle cone = 10.78 inches³.

Now, to get the volume of scoop which is in the shape of sphere we put formula:

Diameter = $2\frac{7}{8} =\frac{23}{8} \ inches.$

Thus radius (r) = Diameter ÷ 2 $=\frac{\frac{23}{8}}{2} =\frac{23}{16} \ inches.$

$Volume = \frac{4}{3} \pi r^3$

$Volume = \frac{4}{3} \times 3.14\times \frac{23}{16} \times \frac{23}{16} \times \frac{23}{16}$

$Volume=1.33\times 3.14\times 1.44\times 1.44\times 1.44$

$Volume=12.47\ inches^3.$

The volume of one scoop of ice cream = 12.47 inches³.

So, as the volume of scoop of ice cream is more than the volume of cone.

Thus, if placing one scoop of ice cream in the cone and let it melt, the cone will not hold all of the ice cream.

Therefore, no the cone will not hold all of the ice cream.

PLS HELP WILL MARK BRAINLIESTTT What is the solution to this inequality?

vagabundo [1.1K]

Answer:

a. x > 0.2

Step-by-step explanation:

In either order, subtract the left-side constant and divide by the x-coefficient.

3x +2.4 > 3

3x > 0.6 . . . . . . subtract 2.4

x > 0.2 . . . . . . . divide by 3

x + 0.8 > 1 . . . . divide by 3

x > 0.2 . . . . . . . subtract 0.8
