Answer:
x =5.25
Step-by-step explanation:
Comment
So you want to find x? If the scale factor is 1.75 it means that you multiply whatever dimension on Figure A by 1.75 to get the corresponding dimension on B.
Formula
x = 1.75 * 3
Solution
x = 1.75 * 3
x = 5.25
The answer is <span>1) ± √x+81
</span>
Step 1: Substitute y for f(x). <span>
Step 2: </span>Since every (x, y) has its partner (y, x)y switch x and y.
Step 3: <span>Solve for y.
Step 1.
The function is: f(x) = x</span>² - 81
Substitute y for f(x): y = x² - 81
Step 2.
Switch x and y: x = y² - 81
Step 3.
Solve for y (which is now f⁻¹(x)): f⁻¹(x) = y
x = y² - 81
y² = x + 81
y = +-√(x+81)
Therefore, the choice 1) is correct.
1. The remaing area of the yard will be found as follows:
Area of the yard
A1=length*width=10x*15x=150x^2 yd^2
area of the fountain
A2=πr²
A2=π(4x)²
=50.266x^2
The remaining area will be:
A=150x^2-50.266x^2
A=99.735x^2 yd^2
2] Area left for bleachers, restrooms and other parts of the stadium will be as follows:
Area of the lot is:
A1=length*width
A1=8x×12x= 96x^2
Area of the field
A2=length×width
A2=3x×6x=18x^2
Hence the remaining area will be:
A1-A2
=96x^2-18x^2
=78x^2 sq. units
Answer:
The probability of a person having a driving accident while intoxicated is 0.07
Step-by-step explanation:
Hi, well, let´s put this on a formula, I think it is the best way to explain it.
Where:
P(A+I) = Probability of having a driving accident while intoxicated.
P(A) = Probability of a person of having an accident.
P(I) = Probablity person being intoxicated.
P(A or I) = Probability of a person for being intoxicated or having an accident.
Therefore, things should look like this:
So, the probability of a person having a driving accident while intoxicated is 0.07.
Best of luck.
