(33-3) division symbol 10-5 with an exponent of 2

Mathematics
1 answer:
lianna [129]3 years ago
4 0

Answer: The answer is -22.

Step-by-step explanation:

Our problem is (33-3) ÷ 10-5^2. We can use PEMDAS to solve it.

First, let's eliminate the parenthesis. 33-3 is 30. The problem is now 30 / 10-5^2.

Next, let's get rid of our exponent. 5 to the second power is the same as 5 x 5 which is 25. The problem is now 30 / 10 - 25.

Then, we have to do division before subtraction. 30 / 10 is 3.

Lastly, 3 - 25 is -22.

What’s the derivative of (2x+9)^3
larisa86 [58]

If f(x) = (2x+9)^3, f '(x) = 3(2x+9)^2*(2), or f '(x) = 6(2x+9)^2.  Here we used the power rule with chain rule to find the derivative.

The wind-chill index W is the perceived temperature when the actual temperature is T and the wind speed is v, so we can write W
melamori03 [73]

Answer:

hello your question is incomplete attached below is the complete question

estimating: Ft( -15,40 ) = ( 1.2 + 1.4 ) / 2 = 1.30⁰c

when the actual temperature is -15⁰c and the wind speed is 40 km/h the apparent temperatures increase by 1.3⁰c  that the actual temperature rises

estimating:  Fv ( -15,40 ) = (-0.2 + -0.1 ) / 2 = -0.15⁰c

when the actual temperature -15⁰c and the wind speed is 40 km/h the apparent temperature decreases by about 0.15⁰c for every km/h that the wind speed

Step-by-step explanation:

A) Estimating the values of Ft(−15, 40) and fv(−15, 40)

attached below is a detailed solution

To estimate the value of Ft( -15,40 ) we have to take an average value hence Ft ( -15,40 ) = ( 1.2 + 1.4 ) / 2 = 1.30

and this means that when the actual temperature is -15⁰c and the wind speed is 40 km/h the apparent temperatures increase by 1.3⁰c  that the actual temperature rises

To estimate the value of Fv(-15,40 )  we have to take an average value

hence Fv ( -15,40 ) = (-0.2 + -0.1 ) / 2 = -0.15

and this means that when the actual temperature -15⁰c and the wind speed is 40 km/h the apparent temperature decreases by about 0.15⁰c for every km/h that the wind speed

Five workers dig a trench 5 yards long in 5 hours. How many workers are needed to dig a 100 yards long in 100 hours?
Pavlova-9 [17]

I think it would require 100 workers since 1 worker digs up 1 yard.

Hope this helps.
