She could have hiked one 2 mile trail and one 1 mile trail or she could’ve hiked one 2.5 mile trail and another 0.5 mile trail
Answer:
(-5, 0.5)
Step-by-step explanation:
-12+2/2= -5
-9+10/2= 0.5
(-5, 0.5)
Answer:
There are 30 different types of shampoo.
Step-by-step explanation:
Each shampoo has a color-code bottle, lid, and label print.
For bottles, there are five different colors, so there are five different possibilities.
For lids, there are three different colors, so there are three different possibilities.
And for labels, there are two different colors, so there are two different possibilities.
To find how many different types of shampoo can be made, we just need to multiply all the possibilities for colors of bottle, lid and label:
Number of different types of shampoo = 5 * 3 * 2 = 30
The expression for the height is given in quadratic expression form
Ax² + Bx + C
Where A, B, and C are constant
To find the x-coordinate when the graph reaches maximum/minimum, we use the formula
x = -B ÷ 2A
We have
h = -16t² + 112t + 30
The value for A = -16, B = 112, and C = 30
Substitute these into x = -B ÷ 2A we have
t = -112 ÷ (2×-16) = 3.5
The maximum height is reached when t = 3.5 sec
The height when t = 3.5 sec is given
h = -16(3.5)² + 112(3.5) + 30 = 226 feet
