Answer:
d. 16 feet
Step-by-step explanation:
x² + 12² = 20²
x² + 144 = 400
x² + 144 - 144 = 400 - 144
x² = 256
√x² = √256
x = 16
Answer: C
Step-by-step explanation:
We do not have the radius, but we do have the diameter. A diameter is twice the radius, therefore we can divide the diameter by 2 in order to obtain the radius.
Plug this info into the formula.
Answer:
<h2>3x^2+2x−4=0</h2>
Use the quadratic formula to find the solutions
−b±√b^2−4(ac)/2a
Substitute the values
a=3, b=2, and c=−4 into the quadratic formula and solve for x.
−2±√2^2−4⋅(3⋅−4)/2⋅3
Simplify.
x = −1±√13/3
The final answer is the combination of both solutions.
x= −1−√13/3,−1+√13/3
The result can be shown in multiple forms.
Exact Form:
x= −1−√13/3,−1+√13/3
<h3>Decimal Form:</h3>
x=0.86851709…,−1.53518375…

$3.15
11 quarters = $2.75
4 dimes = $0.40
$0.40+$2.75=$3.15
The slopes of perpendicular lines are negative reciprocals.
If one line has a slope of 1/6, then the negative reciprocal would be -6/1 which is simplifies as -6.
The answer is C.
