Provide the length of x
Answer:
10
Step-by-step explanation:
the mid-segment, 5, is parallel to the base of the triangle and the side that the mid-segment is parallel to is always double the length of the mid-segment, so the base of the base is 10. this triangle is an equilateral triangle so the side, x, is also 10.

Which statements represent the relationship between y=3x and y=log3x ?
a. The graphs of functions are symmetric about the line y = 0.
b. The functions are inverses of each other.
c. The graphs of functions are symmetric to each other over the line y = x.
d. The equation y=log3x is the logarithmic form of y=3x .
2 Answers: Choice B and Choice C
====================================================
Explanation:
Choice A is false because all of [tex]y = 3^x[/tex] is above the x axis. There are no portions below the x axis, which means it cannot possibly be symmetric about the x axis.Choice B is true. The exponential undoes the log, and vice versa. This only works if the bases of the exponential and log are the same. In this case, both are base 3.Choice C is true. To visually find the inverse, we reflect over the line y = x.Choice D is false. Converting [tex]y = 3^x[/tex] to logarithmic form leads to [tex]x = \log_3(y)[/tex]. So you'll need to swap the x and y.Is 5/12 closer to 0, 1, 1/2

Amelia wants to rearrange the furniture in her room. She makes a scale drawing of her rectangular room,
in which every 2 inches represents 5 feet. On her scale drawing, the area of the room is 24.96 square
inches. If one side of her room is 12 feet long, how long is the other side of her room, in feet?
Answer:
The other side = 13 feets long
Step-by-step explanation:
Given that :
Scale of drawing : 2 inches represents 5 feets
Area of rectangular room according to scale drawing = 24.96 in²
Length of one side of the room = 12 feets
Length of other side = x
Area of rectangle = Length * width
If :
2 inches = 5 feets
x = 12 feets
x = (12 *2) / 5
x = 4.8 inches
Hence,
For the scaled drawing :
4.8 * width = 24.96
Width = 24.96 / 4.8
Width = 5.2 inches
Converting to feets according to scale:
2 inches = 5 feets
5.2 inches = x feets
x = (5.2 * 5 ) / 2
x = 13 feets
Other side is 13 feets long

Answer:
6/5
Step-by-step explanation:
Remember: to divide a number by a fraction, invert the fraction and multiply.
Here "the number" is 4/5 and you want to divide it by 2/3. Invert the '2/3', obtaining 3/2, and then multiply the '4/5" by '3/2":

What is the slope of the line?
- 1 / 4
- 8 / 17
- 4
- 6
Answer: The slope of the line = 4.
Step-by-step explanation:
We know that ,
Slope of a line passes through [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex] = [tex]\dfrac{y_2-y_1}{x_2-x_1}[/tex]
Here , the line passes through points (2,18) and (8,42).
Then the slope of the given line = [tex]\dfrac{42-18}{8-2}[/tex]
[tex]=\dfrac{24}{6}=4[/tex]
Hence, the slope of the line = 4.

4

Subtract 8 feet from 9 yards, 1 foot.
A. 6 yards, 2 feet
B. 7 yards, 1 foot
C. 6 yards, 1 foot
D. 1 yard, 1 foot
Answer: B
Step-by-step explanation:
I knew I would have 1 foot left so that made sure it wasn’t A then I knew that it the answer had to be in yards so I convert 8 feet into yards which becomes 2.7 so it’s not three which makes I’m not C. So 9 yards minus 2.7 yards would equal the answer B
Answer:
your answer should be A let me know

Which equation could generate the curve in a graph below?
Find the value of this expression if x = 5 and
y = 2.
xy^2/-3
Answer:
The value of this expression is:
[tex]\frac{xy^2}{-3}=-\frac{20}{3}[/tex]Step-by-step explanation:
Given the expression
[tex]\frac{xy^2}{-3}[/tex]
Apply the fraction rule: a/-b = -a/b
[tex]\frac{xy^2}{-3}=-\frac{xy^2}{3}[/tex]
substituting x = 5, y = 2 in the expression
[tex]=-\frac{\left(5\right)\left(2\right)^2}{3}[/tex]
[tex]=-\frac{\left(5\right)\left(4\right)}{3}\:[/tex]
[tex]=-\frac{20}{3}[/tex]
Therefore, the value of this expression is:
[tex]\frac{xy^2}{-3}=-\frac{20}{3}[/tex]Math pic is below

Helppp pleaseeee xxxxx
Answer:
[tex] h = 3\sqrt{3} [/tex]
[tex] c = 4\sqrt{2} [/tex]
Step-by-step explanation:
✔️Finding h using trigonometric ratio:
Reference angle = 60°
Opposite = h
Adjacent = 3
Thus:
[tex] tan(60) = \frac{h}{3} [/tex]
[tex] \sqrt{3} = \frac{h}{3} [/tex] (tan 60 = √3)
Multiply both sides by 3
[tex] 3\sqrt{3} = h [/tex]
[tex] h = 3\sqrt{3} [/tex]
✔️Finding c using trigonometric ratio:
Reference angle = 45°
Hypotenuse = 8
Adjacent = c
Thus:
[tex] cos(45) = \frac{c}{8} [/tex]
[tex] \frac{\sqrt{2}}{2} = \frac{c}{8} [/tex] (cos 45 = √2/2)
Multiply both sides by 8
[tex] \frac{\sqrt{2}}{2} \times 8 = c [/tex]
[tex] \sqrt{2} \times 4 = c [/tex]
[tex] c = 4\sqrt{2} [/tex]
