Answer:
AC = 12
Step-by-step explanation:
From the question, we have that BD is perpendicular to AC
This means that it is at 90 degrees to the base
so we have two similar right triangles
Let us use Pythagoras’ theorem to get the measure of one of the legs (AD and DC)
Let us call the leg x
We have the Pythagoras’ theorem stating that the square of the hypotenuse (the side facing the right angle; 10 here) is equal to the sum of the squares of the two other sides
10^2 = x^2 + 8^2
100 = x^2 + 64
x^2 = 100-64
x^2 = 36
x = √36
x = 6
AD = DC = 6
AC = 2 * AD
AC = 2 * 6
AC = 12
Answer:
Denote the distance from initial position of Emily to the park is D
=> As the first speed is 5 (mile/hour) and second speed is 9 (mile/hour) and total time is 1 and 5/9 hour, we have:
D/5 + D/9 = 14/5
=> (9D + 5D)/45 = 14/5
=> 14D/45 = 126/45
=> 14D = 126
=> D = 9 (mile)
Hope this helps!

Answer:
C
Step-by-step explanation:
Option C is the only one that's linear because it follows all of the rules for a line to be linear. To check, use the process of elimination:
A). When x is an absolute value, the line will not be linear because an input will have two outputs.
B). x cannot be in the denominator of a fraction for the line to be linear
D). Once again, x cannot be an absolute value.
*Note: I'm assuming in option B, 7x is in the denominator and 1 is in the numerator. If the fraction is simply 1/7 multiplied by x, it is linear along with C.
Answer:
3:4?
Step-by-step explanation:
If you fill in the blank for c and d it show 3:4. Sorry if this doesn’t help, I don’t fully understand the question
Are you trying to find the slope between those points?
