Dimension of one of the floors of one room that David wants to install tiles is 18feet long by 12 feet wide
Then
Area of the above room = 18 * 12 square feet
= 216 square feet
Dimension of the floor of the other room that David wants to install tiles is 24 feet long and 16 feet wide
Then
Area of the other room = 24 * 16 square feet
= 384 square feet
Then
The total square feet of the
rooms that David wants to install tiles = 216 + 384
= 600 square feet
Cost of the tile that covers 1 square feet = $5
Cost of the 4 tiles that cover 4 square feet = $17
Then
Area that can be covered with 4 square feet of tiles = 600/4 square feet
= 150 square feet
Minimum cost of covering
the two rooms that David wants to install tiles = 150 * 17 dollars
= 2550 dollars
So the minimum cost of installing the tiles on the two floors of David's two rooms is $2550. I hope the procedure is simple enough for you to understand.
You’re given g(x) = x^2 - 5
When asked to find g(9), you’re being told that x=9, since the x in the g(x) was replaced by 9.
So that’s telling you to put 9 in for all x’s:
g(9) = (9)^2 - 5
You then just need to clear up the right hand side.
9^2 - 5 = 81 - 5
= 76
So, g(9) = 76
Answer:
20.5
Step-by-step explanation:
Let's label the vertices ABC as in the diagram below. Then
Data:
α = 34 °
β = 90 °
c = 17
Calculation:
cosα = AB/AC
Multiply each side by AC
ACcosα = AB
Divide each side by cosα
AC = AB/cosα = 17/cos34 ≈ 17/0.8290 ≈ 20.5
Answer:
-13-9a
Step-by-step explanation:
The values on the interval [0, 2π) that makes f (θ) equal to g(θ) is; A: 0, π
<h3>How to solve Trigonometric Functions?</h3>
We are given the trigonometric functions;
f(θ) = 4sin θ + 1
g(θ) = cos 2θ
We know from trigonometric identities that;
cos 2θ = 1 - 2sin²θ
At f(θ) = g(θ), we have;
4sin θ + 1 = 1 - 2sin²θ
2sin²θ + 4sin θ = 0
2sinθ(sin θ + 2) = 0
2sinθ = 0
θ = sin⁻¹(0/2)
θ = 0, π
