then plug 3 into equation
- 3(3)² + 18(3) + 7
the answer is 34
a whale costs $14700 and depreciates in value by 8% per year. When will the whale be worth $100
Answer:
x = 60
Step-by-step explanation:
The question is asking
$14,700 * (1 - 8%)^x = $100
$14,700 * (1 - 0.08)^x = $100
$14,700 * (0.92)^x = $100
(0.92)^x = $100/$14,700
log(0.92^x) = log($100/$14,700)
x * log(0.92) = log(0.0068027)
x = log(0.0068027)/log(0.92)
x = 59.85
Since this question is asking in terms of years, we always round up (in this case to 60), as it won't fully be worth $100 by the beginning of the 59th year.

Either enter an exact answer in terms of 7 or use 3.14 for and enter your answer as a decimal.
C
r= 1
Answer:
area: 3.14
Step-by-step explanation:
because the radius is one, one squared is the same as itself, then by multiplying one by pi, you simply get pi. Therefore making 3.14 your answer.
the answer should be 3.14 or 3.14159

What is the value of x in the triangle?
Answer:
D. 5√3
Step-by-step explanation:
tan 30° = x/15
or, 1/√3=x/15
or, x= 15/√3 = 5√3
Answer:
D
Step-by-step explanation:
Using the tangent ratio in the right triangle and the exacy value
tan30° = [tex]\frac{1}{\sqrt{3} }[/tex] = [tex]\frac{\sqrt{3} }{3}[/tex] , then
tan30° = [tex]\frac{opposite}{adjacent}[/tex] = [tex]\frac{x}{15}[/tex] = [tex]\frac{\sqrt{3} }{3}[/tex] ( cross- multiply )
3x = 15[tex]\sqrt{3}[/tex] ( divide both sides by 3 )
x = 5[tex]\sqrt{3}[/tex] → D

The points (12, 23) and (14, 45) lie on a line. What is
the slope of the line?
Answer:
slope= 11
Step-by-step explanation:
(12,23) = (x1,y1)
(14,45) = (x2,y2)
Now,
slope(m)= (y2-y1)/(x2-x1)
=(45-23)/(14-12)
=22/2
=11

Solve the following quadratic equation for all values of xx in simplest form.
5(2x+1)^2+6=26 cant figure this out!!
Answer:
x=1/2 and x=-3/2
Step-by-step explanation:
5(2x+1)^2+6=26
5(2x+1)^2=20
(2x+1)^2=4
2x+1=±2
Now make two equations and solve both for x:
2x+1=2
2x=1
x1=1/2
2x+1=-2
2x=-3
x2=-3/2

The length of each of the legs of an isosceles triangle is represented by the expression 5x-2 inches. The length of the base of the isosceles triangle is represented by the expression 3x +1 inches. The perimeter of the isosceles triangle is 42 inches.
determine whether each equation represents the perimeter of the isosceles triangle , in inches .
select yes or no for each equation
A. 13x-2=42 yes or no
B. (10x-2)+(3x+1)=42 yes or no
C.2(5x-2)+2(3x+1)=42 yes or no
D.5x-2+3x+1+5x-2=42 yes or no
THERE CAN BE MORE THAN ONE ANSWER.
thank you
Answer:
A.NoAs,
5x - 2 + 5x - 2 + 3x + 1 = 13x - 3 = 42
But here,
13x - 2 which is not equal to 13x - 3
Hence, it's wrong.
B. NoAs,
5x - 2 + 5x - 2 + 3x + 1 = (10x - 4) + (3x + 1) = 42
But here,
(10x - 2) + (3x + 1) which is not equal to (10x - 4) + (3x + 1)
Hence, it's wrong.
C. NoAs,
5x - 2 + 5x - 2 + 3x + 1 = 2(5x - 2) + 3x + 1 = 42
But here,
2(5x-2)+2(3x+1) which is not equal to 2(5x - 2) + 3x + 1
Hence, it's wrong.
D. YesAs,
5x - 2 + 5x - 2 + 3x + 1 = 42
Also,
5x-2+3x+1+5x-2 equal to 5x-2+3x+1+5x-2
Hence, it's correct.

PLEASSEEEE HELPPP ME HURRRYY
Answer:
8 = D
9 = D
10 = D
Step-by-step explanation:
For 8, a straight line is 180 degrees, and if PQS is already x+55, then RQS is also x, so it would be 2x +55 = 180
For 9, surface area is just area of the sides of a shape, so (3*15)*2 + (6*3)*2 + (5*6)*2 which equals 30 +36 + 60, which is 126.
For 10, the volume is the width*length*height, so 4*4*11 = 16*11 = 176, and because there are 6 rectangular prisms, 176*6 which is equal to 1056.
