Answer:
15°F
Step-by-step explanation:
It is given that,
Today's high temperature is 72°F and yesterday's high temperature was 87°F. We need to find the change in high temperatures.
Change in temperatures = final temperature - initial temperature
= 87°F - 72°F
= 15°F
It means that the change in temperature is 15°F. Hence, the correct option is (b).
Answer:
D
Step-by-step explanation:
Angles outside a circle are half the difference of the measures of the intercepted arcs.
78 - 12 = 66
66/2 = 33
The angle is 33 degrees
Answer:
It was difficult reading the question, as written. Check my assumptions.
Step-by-step explanation:
"five more than the product of two and a number,
decreased by seven"
---
Let the "number" be a.
We are told "five more than . ." means +5,
"the product of two and a number" means 2a,
"decreased by seven" mean -7
Put the statements together to obtain:
+5+2a-7
Simplify to 2a-2
Evaluate when a = 8:
2a-2
2(8)-2
16-2
= 14
Answer:
See below
Step-by-step explanation:
Your question is a bit unclear, so I'm going to assume you want the value of y or x:
(y+3)^2=-12(x-2)
-(y+3)^2/12=x-2
-(y+3)^2/12+2=x
(y+3)^2=-12(x-2)
y+3=sqrt(-12x+24)
y=sqrt(-12x+24)-3
