Answer:
x = 3√5
Step-by-step explanation:
we can use the Pythagorean Theorem twice, first to find the longer leg of the left triangle:
7² + b² = 10²
b² = 100-49
b² = 51
b = √51 which we can simplify to be √9·√3·√3 = 3·3 = 9
we can use the Pythagorean Theorem next to find 'x':
x² + 6² = 9²
x² + 36 = 81
x² = 45
x = √45 = √9·√5 or 3√5

(2^2)^4 = 256
3^4 = 81
256 × 81 = 20735
27 × 16 = 432
20735÷432 = 47.99
round to 47.99 to the nearest 10th and you will get 48.

II. f−1(4) when f(x) = 3x - 4 over 5
III. 3y − 6 = y + 10
Answers
Answer:
I don't think that there is two same results. sorry I couldn't help
Step-by-step explanation:
for I the answer should be 10 if you replaced each x by 2. f(2) = 3(2) + 4
and for II it will be f-1(4) = 3-1(4) - 4 /5 the answer will be -1.
for III it should be y = 8 or 4

12) There are two rectangular doors that are similar. The smaller door has a height of 3 ft. and a width of 2 ft. The bigger door has a width of 8 ft. What is the height of the bigger door? (Draw a picture, set up a proportion, and show all work.)(3pts)
Answers
Answer:
it's twelve you're welcome
Answer:
12 ft
Step-by-step explanation:
Since the doors are similar then the ratios of corresponding dimensions are equal.
let x be the height of the bigger door, then
[tex]\frac{small}{big}[/tex] : [tex]\frac{3}{x}[/tex] = [tex]\frac{2}{8}[/tex] ( cross- multiply )
2x = 24 ( divide both sides by 2 )
x = 12
Height of the bigger door is 12 ft
If these are correct.

3400 km is decreasing at a rate of 6.5% each year so after 7 years how much is left
Answers
Answer:
1547 km
Step-by-step explanation:
1547 km remain due to consistent decrease in the rate of 3400 km. As stated 6.5% decreases each year, and you are wanting to see the amount left after 7 years. So I said 0.065 x 7 = 0.455 (Because you want to move the decimal two places to the right in this case when plugging in the percentage into an equation.) So, now since I'm left with0.455 for the 7 years I simply multiplied that by 3400 km to get my answer. Which gave me the value 1547 km.

21.) x = 0
22.) x = 8
23.) x = 0
24.) x = 12
Step-by-step explanation:
21.) x + 12 = 12
=> x = 0
22.) x - 1 = 7
=> x = 8
23.) 12 + 2x = x + 12
=> 12 + x = 12
=> x = 0
24.) 2x - 14 = 10
=> 2x = 24
=> x = 12
(All of these equations are set equal to their opposite side on the same figure since both the sides are parallel and congruent)

24 inches
Answer:
[tex]\boxed {\boxed {\sf 24 \ inches}}}[/tex]
Step-by-step explanation:
We want to find the diameter of the tire given the distance traveled in 1 full rotation.
The circumference of a circle is the distance all the way around. If a wheel or tire makes 1 full rotation, the distance traveled is equal to the circumference.
The circumference is the product of pi and the diameter.
[tex]c=\pi \times d[/tex]
We know the circumference (distance traveled in 1 full rotation) is 75 inches. We can substitute this value for c.
[tex]75 \ in =\pi \times d[/tex]
We want to find the diameter, so the variable must be isolated. It is being multiplied by pi. The inverse of multiplication is division, so we divide both sides by pi.
[tex]\frac {75 \ in}{\pi}= \frac{\pi \times d}{\pi}[/tex]
[tex]\frac {75 \ in}{\pi}=d[/tex]
[tex]23.8732415 \ in=d[/tex]
Round to the nearest inch. The 8 in the tenths place tells us to round the 3 up to a 4.
[tex]24 \ in \approx d[/tex]
The diameter of the tire is approximately 24 inches.

Solve the quadratic equation by completing the square. 0 = x2 – 6x + 4 –4 = x2 – 6x –4 + 9 = (x2 – 6x + 9) 5 = (x – 3)2
Answers
Answer:
x = 3±√5
Step-by-step explanation:
Given the quadratic equation;
0 = x² – 6x + 4
Swap sides
x² – 6x + 4= 0
Subtract 4 from both sides
x² – 6x + 4 - 4= 0 - 4
x² – 6x = -4
Complete the square;
Add the square of half of coefficient of x to both sides
Coefficient of x = -6
Half of Coefficient of x = -6/2 = -3
square of the half of Coefficient of x = (-3)²
Add (-3)² to both sides
x² – 6x + (-3)² = -4 + (-3)²
(x-3)² = -4 + 9
(x-3)² = 5
Take the square root of both sides
x - 3 = ±√5
x = 3±√5
This gives the solution to the equation
