At what values of x does f(x)=0?

Mathematics
1 answer:
andriy [413]3 years ago
7 0

Answer:

Step-by-step explanation:

Look for the three dots on the x-axis:  You find them at -1, 2 and 4.

At these x-values the function has zeros (roots or solutions).

Thus, the 3 correct answers are B (x = 2) and F (x = 4).  -1 is also a solution, but is not listed.

Find three consecutive odd numbers such that the sum of five times the smaller number and twic the larger number is 33 more than
stiv31 [10]

Answer:

37, 39, and 41

Step-by-step explanation:

let the numbers are A, (A+2), (A+4)

the equation could be :

5A + 2(A+4) = 33 + 6(A+2)

5A+2A+8 = 33 + 6A+12

7A+8 = 45+6A

7A-6A = 45-8

A = 37

so, the three odd numbers are :

37, 39, and 41

Simplify 2/4 please and thank you
klio [65]

Answer:

1/2

Step-by-step explanation:

2/4 is equal to 1/2, because if you divide 4 by 2 you get 2, and if you divide 2 by 2 you get one.

Basically, the simplification process would look something like this...

2/4 ÷ 2/2 = 1/2

Find the volume of the cone shown, if r=8 cm and AC=AB=17 cm
Papessa [141]

Answer:

1005.3 cm³

Step-by-step explanation:

The radius of the cone (r) is 8 cm and the slant height is AC = AB = 17 cm.

Therefore, the height of the cone (h) will be given by \sqrt{17^{2} - 8^{2}} = \sqrt{225} = 15 cm.

We have to calculate the volume of the cone.

Therefore, the volume of the cone will be given by \frac{1}{3}\pi  r^{2}h

= \frac{1}{3} \times \frac{22}{7} \times 8^{2}\times 15

= 1005.3 cm³ (Answer)
