Given 4 c + 5 not-equals 0 and c is a real number, what is the multiplicative inverse of 4 c + 5 not-equals 0
0
1
StartFraction 1 Over 4 c + 5 End Fraction
StartFraction 1 Over 4 c EndFraction + 5

Answers

The multiplicative inverse is 1 / (4c + 5).

In mathematics, the multiplicative inverse of a number is the reciprocal of that number. In other words, if we have a non-zero number "a", then its multiplicative inverse is the number "1/a", which when multiplied by "a" gives the product of 1.

The multiplicative inverse of a number a is the number that when multiplied by a gives the product of 1. In other words, if a is not equal to 0, the multiplicative inverse of a is 1/a.

In this case, we are given that 4c + 5 is not equal to 0. Therefore, the multiplicative inverse of 4c + 5 is:

1 / (4c + 5)

So, the correct answer is 1 / (4c + 5).

10 A frustum is a portion of a solid. The frustum shown opposite is formed from a cone.
a What is the volume of the missing top cone? Give answers correct to the nearest cubic metre.
b What was the volume of the entire cone?
c What is the volume of the frustum?

Answers

Step-by-step explanation:

all you needed to do was a quick search on the internet : "volume of a cone".

and you get immediately :

pi×r²×h/3

the reason is similar to all other volume formulas : base area times height. for pyramids and cones there are factors included to reduce this a bit, because they simply don't go straight up from their base area, so they have less volume than comparable objects that do go straight up (like a cylinder compared to a cone).

r = radius

h = height

so, for a) we only need to use the calculator :

pi × 5² × 30 / 3 = pi×25×10 = 785.4 ≈ 785 m³

for b) we need to do the same thing, but with r = 10 and h = 60.

pi × 10² × 60 / 3 = pi×100×20 = 6283.2 ≈ 6283 m³

so, for c) we only need to subtract the result of a) from the result of b)

the frustum is the volume of the large cone minus the volume of small, top cone.

6283 - 785 = 5498 m³

C. Find the equation of the line perpendicular to
y = 14x-5 and passing through (2,-3).

Answers

Answer:

y = -1/14x - 20/7

Step-by-step explanation:

An equation consists of y = mx + b.

m = slopeb = y - intercept

- When a line is perpendicular, the slope becomes the opposite.

14 = -1/14

- Now, that we have the slope, all we need to do is find the y-intercept/b.

y = -1/14x + b

-3 = -1/14(2) + b

-3 = -1/7 + b

-20/7 = b
