Answer:
By using the pythagorean theorem a^2 + b^2 = c^2
D is the correct answer Where PQ
= √15^2+√19^2
=√ 225 + √361
= √ 586
Length of PQ = √586 = 24.2074368738(ans)
B
if it is not correct sory
If two functions are inverse of each other, they are basically switching the x- and y-axes.
Take for example, p(x)=2x, is a line passing through the origin with a slope of two. Its inverse, q(x)=x/2, is a line passing through the origin with a slope of 1/2, the reciprocal of 2. If you plot the two lines, you will notice that the two lines are symmetrical about y=x, or a 45 degree line from the x-axis.
This also explains y=x (which lines on the line of reflection) has its inverse also equal to y=x!
So, the first thing you should do is break it down. First how much space can she have, and how many hotdogs and hamburgers would she have know the amount of space. Then you would find the amount of money she would make if she sold the food, and how much she would spend for inventory. Hope this helps!
Answer: 190,000 pounds
Step-by-step explanation:
Amount won by Gail= 500,000
Amount spent on sports car= 120,000
Money left = Amount won minus amount spent on sports car
= 500,000 - 120,000
= 380,000
Then she spends half of the amount left on her apartment
= 1/2 of 380,000
= 1/2 × 380,000
= 190,000
Her apartment costs 190,000 pounds
