Answer:
Step-by-step explanation:
BC = 60
CA = 45
AB = sqrt(45^2 + 60^2)
AB = sqrt(2025 + 3600)
AB = sqrt(5625)
AB = 75
the assumption being that "x" is a plain variable whilst "y" is a function, that matters because the chain rule would be needed for a function, not so for a plain variable.
now, we know that y(5) = -23, which is another way of saying that when x = 5, y = -23, but we already knew that, we can get that by simply plugging it into the equation hmmm y'(5), well
Answer:
16
Step-by-step explanation:
3 |a-b| +2|b-1|
a= -2 and b=-4
3 |-2--4| +2|-4-1|
3 |-2+4| +2|-4-1|
3 |2| +2|-5|
Absolute value means takes whatever is inside and make it positive
3*2 +2*5
6 +10

Answer:
max wil sell 52 because the first hour he sold 12 5hours -1 hour = 4 hour
4 hour × 10 p/h= 40
max sold 12+40 =52
leah will sell 58 because the first hour she sold 8
5hours - 1hour = 4 hours
4hours× 10 glasses p/h = 40
leah sold 40+8 =48 glasses
Answer:
Lauren's triangle is an isosceles triangle
Step-by-step explanation:
Given the sides of a triangle as 7mm, 9mm and 7mm.
From the given sees you will see that two of the sides are the same showing that the triangle is an isosceles triangle.
An isosceles triangle is a triangle that as two of its sides equal and since two of the sides are both 7mm, hence Lauren's triangle is an ISOSCELES TRIANGLE
