I need help with geometry homework.
Use the figure to name each of the following.
1. The intersection of TV and US.
2. The intersection of US and plane R.
3. The intersection of TU and UV.
The point at which lines, planes and points meet is referred to as the point of intersection or simply intersection.
The intersection of TV and US, US and plane R & TU and UV is point U
From the attached figure, we have the following observations
1. Line segments TV and US intersects at point U.
This means that the intersection of TV and US is point U
2. Line segment US and plane R intersects at point U
This means that the intersection of US and plane R is point U
3. Line segments TU and UV intersects at point U
This means that the intersection of TU and UV is point U
Hence, the name of the three intersections is point U

Answer:
Step-by-step explanation:

The angles are vertically opposite. Vertically opposite angles are equal.
12x - 5 = 10x + 1 Add 5 to both sides.
12x = 10x + 5 + 1 Combine
12x = 10x + 6 Subtract 10x from both sides.
12x - 10x = 6 Combine
2x = 6 Divide by 2
x = 6/2
x = 3
10
Adjacent angles to each other when sharing a side are supplementary
4x + 7 + 2x + 5 = 180 Combine like terms on the left
6x + 12 = 180 Subtract 12 from both sides
6x = 180 - 12 Combine
6x = 168 Divide by 6
x = 168 / 6
x = 28

Answer:
X should equal 12.
Step-by-step explanation:
I say this because we know TED= 30° bc 50°-20° = 30
then u have to think about what × 2 + 6 equals 30
sure enough 12 × 2 = 24 and 24 + 6 = 30
that's why I say X equals 12

1. Find the distance between the pair of points: (-8, -2) and (-4,5)
Hi, I'm happy to help!
To solve, this, we need to find the distance in x coordinates, y coordinates, then use the Pythagorean Theorem, let's solve!
First, we have to find the distance in x coordinate values. The first coordinate is -8, and the second is -4, which means there is an x distance of 4.
Next, we need to find the distance in y coordinate values. The first coordinate is -2, and the second is 5, meaning there is a y distance of 7.
From here, we use the Pythagorean Theorem. This states that a²+b²=c².
This applies to right triangles, which is what we have. The x distance is a, the y distance is b, and the overall distance is c. We need to find c to answer the question. Let's plug in our values:
4²+7²=c²
16+49=c²
65=c²
To find c, we need to find the square root of 65.
√65
8.0622577...
Rounding to the nearest tenth is 8.1.
The distance between the two points is about 8.1.

[tex] \displaystyle \large \tt{ \sin a = \frac{opposite}{hypotenuse} }[/tex]
First, we have to focus on ∠a, at the angle a or ∠a, the opposite is z because ∠a is the opposite side of z.
The hypotenuse side is always x, even if we change from ∠a to ∠b (b = 90°-a)
So what we have now are:
opposite = z (Refer to the bold text)hypotenuse = x (hypotenuse is always the side that is opposed to a right angle.)Substitute the letter in the ratio:
[tex] \displaystyle \large \boxed{ \sin a = \frac{z}{x} }[/tex]

12 in Mathematics and 16 in Science
Step-by-step explanation:
12+16=28
12+3=15 and 16-4=12
15*12=180
Answer:
He got 12 marks in mathematics and 16 in science.
Step-by-step explanation:
M + S = 28, (M + 3)(S - 4) = 180.
(M + 3)(S - 4) = MS - 4M + 3S - 12 = 180
MS - 4M + 3S - 12 = 180
MS - 4M + 3S = 192
M + S = 28
S = 28 - M
M(28 - M) - 4M + 3(28 - M) = 192
28M - [tex]M^{2}[/tex] - 4M + 84 - 3M = 192
-[tex]M^{2}[/tex] + 21M = 108
-[tex]M^{2}[/tex] + 21M - 108 = 0
(-M + 9)(M - 12) = 0
M = -9, 12
S = 37, 16
1st solution:
(-9 + 3)(37 - 4) = 180
-6 * 33 = 180
-198 = 180
2nd solution:
(12 + 3)(16 - 4) = 180
15 * 12 = 180
180 = 180
Therefore, M = 12 and S = 16.

Classify 7/8 as either a whole number natural number an integer or rational number
Answer:
rational number
Step-by-step explanation:
a whole number is a non-negative integer, a natural number is a positive integer, an integer is any number that doesn't have decimal places and isn't a fraction. 7/8 isn't an integer so it isn't a whole or natural number. rational numbers can be written as fractions or are terminating decimals. 7/8 is a fraction so 7/8 is a rational number
Given the definitions of f(x) and g(x) below, find the value of (gºf)(-4).
f(x) = -2x - 3
g(x) = 2x2 – 2x – 8
Answer:
[tex](g\circ f)(-4) = 32[/tex]
Step-by-step explanation:
We are given the two functions:
[tex]f(x) = -2x - 3\text{ and } g(x) = 2x^2 - 2x - 8[/tex]
And we want to find the value of:
[tex](g\circ f)(-4)[/tex]
Recall that this is equivalent to:
[tex]\displaystyle = g(f(-4))[/tex]
Find f(-4):
[tex]\displaystyle \begin{aligned}f(-4) &= -2(-4) - 3 \\ &= 5 \end{aligned}[/tex]
Hence:
[tex]g(f(-4)) = g(5)[/tex]
Finally, find g(5):
[tex]\displaystyle \begin{aligned}g(5)& = 2(5)^2 - 2(5) - 8 \\ &= 32 \end{aligned}[/tex]
In conclusion:
[tex](g\circ f)(-4) = 32[/tex]

6 . The scale of a map is 1: 250 000. (a) The actual distance between two cities is 80 km. Calculate this distance on the map. Give your answer in centimeters. (b) On the map a large forest has an area of 6 cm?. Calculate the actual area of the forest. Give your answer in Square kilometres.
Answer:
The scale of a map is 1:250000.The actual distance between two cities is 80 km. Calculate this distance on the map. Give your answer in centimetre
Step-by-step explanation:
1 m = 100 cm
1 km = 1000 m = 100 000 cm
1:250 000 mean that 1 cm on the map represents an actual distance of 250 000 cm = 2.5 km
1:250 000 = 2.5 km / cm
80 km / 2.5 km / cm = 32 cm
OR
80 km = 8 000 000 cm
8 000 000 cm ∙ 1 / 250 000 = 8 000 000 cm / 250 000 = 32 cm
