If q(x)=7x^2-1 ; find Q(-10)

Mathematics
1 answer:
maksim [4K]3 years ago

In terms of PEMDAS, you would first find -10 squared, which is 100, and multiply it by 7, giving you 700-1. The answer would be 699.

If you weren't going by PEMDAS, then you would take 7, multiply it by -10, square that, and subtract one from it. -70^2=4,900. Subtract 1, and your answer is 4,899.

Vusi makes bead bracelets in different designs. The first design uses 23 beads, the second design uses 29 beads and the third de
sergey [27]

When the remainder theorem is applied to the total number of beads, the number of beads left is 3

<h3>What is remainder theorem?</h3>

The question is an illustration of remainder theorem. Remainder theorem is used to determine the remainder when a number divides another

The number of beads used in each design are given as:

First = 23

Second = 29

Third = 31

Calculate the total number of beads used for all three designs

Total =First + Second + Third

Total =23 + 29 + 31

Total =83

The number of available beads is:

Available = 750

Divide 750 by 83, to get the total number of designs

n = \frac{750}{83}

n =9.03

Remove decimal (do not approximate)

n = 9

The number of beads remaining is calculated using:

Remaining =Available -n \times Total

Remaining =750 -9 \times 83

Remaining =3

Hence, there are 3 beads remaining

How many of each type of box is it carrying?
CaHeK987 [17]

Answer:

Number of large boxes: 55

Number of small boxes:65

Step-by-step explanation:

Let be "l" the number of large boxes and "s" the number of small boxes.

Set up a system of equations:

\left \{ {{l+s=120} \atop {60l+30s=5250}} \right.

Use the methof of elimination. Mulitply the first equation by -60 and add both equations. Then solve for "s":

\left \{ {{-60l-60s=-7200} \atop {60l+30s=5250}} \right.\\.........................\\-30s=-1950\\s=65

Substitute s=65 into any of the original equations and solve for "l":

l+65=120\\l=55
