If p(x)= 10x^2+10x-3, find p(-4)

Mathematics
1 answer:
PIT_PIT [208]3 years ago
4 0

Answer:

Step-by-step explanation:

What this means is when you start with P(x) you get 10^2 + 10x - 3 on the right

p(-4) has the meaning that when you see an x on the right hand side, you put in -4 for that x. Do this procedure for every x on the right.

p(-4) = 10(-4)^2 + 10(-4) - 3

p(-4) = 10*16 + (-40) - 3

p(-4) = 160 - 40 - 3

p(-4) = 120 - 3

p(-4) = 117

A company purchased land, a building, and equipment for one price of $800,000. The estimated fair values of the land, building,
Ksenya-84 [330]

Answer:

$80,000

Step-by-step explanation:

Given:

Total purchase amount = $800,000

Fair values for:

Land = $100,000

Building = $700,000

Equipment = $200,000

Total fair value of the purchase = $100,000  + $700,000  + $200,000

=  $1,000,000

Allocation Percentage Amount of Basket Purchase for land

= ( Fair value ÷ Total fair value of the purchase ) × 100%

= ( $100,000 ÷ $1,000,000 ) × 100%

= 10%

Hence,

Amount at which the land would be recorded

= Allocation Percentage × Total purchase amount

= 10% × $800,000

= $80,000

A badminton club has 330 members. 240 are adults and the rest are children. Two thirds of the children are boys and the rest are
Margaret [11]

Answer:

The number of boys last year will be 50 boys

Step-by-step explanation:

330 members with 240 adults

The number of children will be;

330-240 = 90

2/3 of 90 are boys

= 2/3 * 90 = 60 boys

Number of girls is 90-60 = 30

Ratio of adults:boys:girls

= 240:60:30

divide through by 30

= 8:2:1

b) A year ago, there were 200 adults but the ratio still remains same

Let the number of girls be x, the number of boys will be 2x

Thus, total number is 200 + x + 2x = 200 + 3x

Total ratio is 8 + 2 + 1 = 11

mathematically;

8/11 * (200 + 3x) = 200

8(200 + 3x) = 11(200)

1600 + 24x = 2200

24x = 2200-1600

24x = 600

x = 600/24

x = 25

So the number of boys will be 25 * 2 = 50
