Find the value of z.
Answer:
6√2=z
Step-by-step explanation:
As we are given a right angle we simply can apply the formula a²+b²=c².
A = 3
B = z
C = 8+1 which we add to get 9
Now, we plug this into the equation
9²=z²+3²
81=z²+9
72=z²
√72=z
√2x2x2x3x3 (expanding 72)

5. The equation y=3/2 is rotated 180° around the origin. What is the equation of the image line?
Answer:
(d) y' = 3/2x
Step-by-step explanation:
The transformation for rotating a figure 180° about the origin is ...
(x, y) ⇒ (-x, -y)
__
Given the line ...
y = 3/2x
The translation of it is ...
-y' = 3/2(-x)
Simplifying gives ...
y' = 3/2x
_____
Additional comment
Rotation 180° about the origin is equivalent to reflection across the origin. For a line that passes through the origin, that reflection is simply the original line, as we can see in the equations above.

Table 101 х 30 5080 y 10 18 25 9 from "Table 101" To evaluate the fit of a model, the absolute values of the deviations (differences between the actual data values and values predicted by the model) are added together. Order the models based on the these total deviations. Place the model with the smallest total absolute deviation on top. y = 0.4x - 2 = - y = 0.3x + 2 y = 0.3x + 1
Answer:
We can determine that Option A, y = 0.4x - 2 is the correct answer
Step-by-step explanation:
Step 1: Plug in 30 into the x-value to see if the y-value matches
Equation 1 --> y = 0.4(30) - 2 = 10
Equation 2 --> y = 0.3(30) + 2 = 11 <-- WRONG Y-VALUE
Equation 3 --> y = 0.3(30) + 1 = 10
Step 2: Plug in 50 into the x-value to see if the y-value matches
Equation 1 --> y = 0.4(50) - 2 = 18

Below is a scale drawing of a ballroom that mika is designing. a rectangle with length 11 inches and width 4 inches. using the scale 1 in. : 4 m, mika calculated the length, or the longer side of the ballroom, to be 44 m. she decides to change the scale to 1 in. : 7 m. what is the length of the new ballroom? 16 m 28 m 44 m 77 m
The length of the new ballroom (in reality, the ballroom is designed according to scale drawing) is given by: Option D: 77 m
How are scale drawings formed?For a particular scale drawing, it is already specified that all the measurements' some constant scaled version will be taken. For example, let the scale be K feet to s inches.
Then it means
[tex]\rm 1\: ft : \dfrac{s}{k}\: in.[/tex]
All feet measurements will then be multiplied by s/k to get the drawing's corresponding lengths.
We're given that:
The scale that Mika uses: 1 in: 4m (1 inch in drawing is 4 metre in real world).The scale drawing has a rectangle of 11 in to 4 inchThe longer side of the ballroom is 44 mShe changes the scale to: 1 in: 7mLength of new ballroom (the longer length) is to be found.Since in the drawing, 11 inches was representing 44 m length of the ballroom when 1 inch: 4 metre scale was being used (as 11×4=44), so when the scale is 1 inch: 7 meters, then the new length of the ballroom in reality would be: 7 metre 11 times (since there is 11 inches as length of ballroom in the scale drawing)
This evaluates to [tex]7 \times 11 = 77 \: \rm metre[/tex]
Thus, the length of the new ballroom (in reality, the ballroom is designed according to scale drawing) is given by: Option D: 77 m

https://brainly.com/question/8765466
The length or the longer side of the new ballroom is 77m.
Dimensions of the model = 11 inches*4 inches
1 inch = 4m
What is a scale factor?A scale factor is a factor by which the dimension of an object is enlarged.
So, the dimensions of the ballroom will be:
Length = 11*4 = 44m
Width = 4*4 =16m
But, Mika decides to change the scale to 1 inch: 7metres
So, the length of the new ballroom = 11*7 =77m
So, the length of the new ballroom =77m
Hence, the length of the new ballroom is 77m.

Tina started with $20, but had to spend $3.25 on the bat.
$20-$3.25 = $16.75, which is all she has left for rounds.
Each round costs $3.00
$16.75 divided by $3.00 comes out to 5.58 rounds, but since she can't play 1/2 a round, that means she could only play 5 rounds

A 17-foot ladder is placed against a vertical wall of a building, with the bottom of the ladder standing on level ground 10 feet from the base of the building. How high up the wall does the ladder reach?
Answer:
13.747... meters
Step-by-step explanation:
Refer to image attached~
Let AC represent the length of the ladder.Let BC represent the distance from the base of the ladder from the base of the building.Let AB (x) represent the height of the building.In this case, the longest side of the triangle formed is AC. Thus, our hypotenuse is AC (17 m).
To determine the height of the building, we need to use pythogoras theorem.
Pythogoras theorem: (Hypotenuse)² = (Side)² + (Side)²
⇒ (17)² = (10)² + (x)²⇒ 289 = 100 + (x)²⇒ 289 - 100 = (x)²⇒ 189 = (x)²Take square root both sides:
⇒ √189 = √(x)²⇒ x = √189 ≈ 13.747... metersAnswer:
13.75 ft (nearest hundredth)
Step-by-step explanation:
The ladder creates a right triangle with the wall and ground, where:
leg (base) = groundleg (height) = wallhypotenuse = ladderPythagoras' Theorem: a² + b² = c²
(where a and b are the legs, and c is the hypotenuse, of a right triangle)
Given:
a = 10 ftc = 17 ftSubstitute the given values into the formula and solve for b:
⇒ 10² + b² = 17²
⇒ b² = 17² - 10²
⇒ b² = 289 - 100
⇒ b² = 189
⇒ b = ±√(189)
As distance is positive, b = √(189) ft only
Therefore, the ladder reaches 13.75 ft (nearest hundredth) up the wall.
