Answer:
x = 4
Step-by-step explanation:
Using the sine ratio in the right triangle and the exact value
sin45° = [tex]\frac{1}{\sqrt{2} }[/tex]
sin45° = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{x}{4\sqrt{2} }[/tex] = [tex]\frac{1}{\sqrt{2} }[/tex] ( cross- multiply )
[tex]\sqrt{2}[/tex] x = 4[tex]\sqrt{2}[/tex] ( divide both sides by [tex]\sqrt{2}[/tex] )
x = 4

Answers
Answer:
[tex]F = 1.8C +32[/tex]
[tex]F = 86^{\circ}F[/tex]
Step-by-step explanation:
Represent Celsius with C and Fahrenheit with F.
So, we have:
[tex](C_1,F_1) = (100,212)[/tex]
[tex](C_2,F_2) = (0,32)[/tex]
Solving (a): Represent as a linear equation
First, we calculate the slope:
[tex]m = \frac{F_2 - F_1}{C_2 - C_1}[/tex]
This gives:
[tex]m = \frac{32 - 212}{0 - 100}[/tex]
[tex]m = \frac{-180}{- 100}[/tex]
[tex]m = 1.8[/tex]
The linear equation is then calculated using:
[tex]F - F_1 = m(C -C_1)[/tex]
Where
[tex](C_1,F_1) = (100,212)[/tex]
[tex]m = 1.8[/tex]
[tex]F - 212 = 1.8(C -100)[/tex]
[tex]F - 212 = 1.8C -180[/tex]
Make F the subject
[tex]F = 1.8C -180+212[/tex]
[tex]F = 1.8C +32[/tex]
Solving (b): The value of F when C = 30
Substitute 30 for C in [tex]F = 1.8C +32[/tex]
[tex]F = 1.8 * 30 + 32[/tex]
[tex]F = 54 + 32[/tex]
[tex]F = 86[/tex]

There are two ways to graph an equation.
1st Way:
We can use a graphing calculator. (See the attached file)
2nd Way:
We can take the values of x as 0, 1 , 2 (Or anything).
Then, We have to put the values of x in the equation to get the value of y accordingly.
According to these values, Plot the graph.

what is the vaule of m in the expression m^2(2-3m)-6m(1-4m+5m^2)
Answers
Answer:
1 ( 12-3m ) - 5m ( 11-4m+25)
1 ( 9m ) - 5m ( 32m )
9m -5m ( 32m )
4m ( 32m )
32×4 = 128 m
128 m
Answer:
Without an equivalence given (i.e. an equals sign somewhere in the expression), we have no way of solving for m.
We can however simplify it:
m²(2 - 3m) - 6m(1 - 4m + 5m²)
= 2m² + 3m³- 6m + 24m² - 30m⁴
= 26m² + 3m³ - 6m - 30m⁴
= m(-30m³ + 3m² + 26m - 6)

Step-by-step explanation:
Find the difference by subtracting -4.8 from 10.2
10.2 - (-4.8)
Subtracting a negative number changes to adding a positive number:
10.2 + 4.8
= 15
So, the difference in temperature between the two cities is 15°C

Answers
Answer:
15 feet
Step-by-step explanation:
Michele wanted to measure the height of her school's flagpole to place on the ground 35 ft from the flagpole then walks backwards until she was able to see the top of the pole in the mirror her eyes were 5 feet above the ground and she was 12 ft away from the mirror using similar triangles, find the height of the flagpole to the nearest of a foot
Using similar triangles
= Let the height of the flagpole be represented as h.
h/35 =5/12
We cross Multiply
35 x 5 = 12h
12h = 175
h = 175/12
h = 14.583333333 feet
Approximately to the nearest foot is
h = 15 feet

If DF=70, find the value of x.
Answers
Answer:
x = 12
Step-by-step explanation:
DE + EF = DF
2x - 1 + 5x - 13 = 70
7x - 14 = 70
7x = 70 + 14
= 84
x = 84 ÷ 7
x = 12
Answer: x=12
Step-by-step explanation:
2x-1+5x-13=70
Combine like terms
7x-14=70
Add 14 to both sides
7x=84
Divide both sides by 7
X=12

Can someone please help me with this? I know its C cause someone answered it. ut didnt explain.
Answers
Answer:
c) 160,000
Step-by-step explanation:
Since we know that the population of both city x and city y are equal in 2015, we can use the population growth of population of city x to find the population in 2015:
120,000 x 1.2 = 144,000.
Now, since we know that City Y's population decreased 10% from 2010 to 2015, we can divide the 2015 population of city Y (which is the same as city x - 144,00) by 1 - decrease rate to find city y's population in 2010:
1 - .1 = .9
144,000 / .9 = 160,000

AB formed by (0-2) and (0,7)
CD formed by (3,-5) and (6,-5)
Answers
Answer:
AB is undefined, CD is y = -5
Step-by-step explanation:
Find both of the line's slopes. You can use the formula for slope to calculate this answer because you know two points on the line for both lines (Look below). If you plug in the points for AB, you would have ( -2 - 7)/0, which would be undefined, because anything divided by 0 is undefined. Since the slope for AB is undefined, it is undefined. Next, we have CD. If you plug in the points for CD, you would get (-5 - (-5))/(6 - 3), which would be 0/3, which is 0. This means that the slope is 0. Next, we have to plug in the points for CD into the formula for equation of the line (Look Below), which would be y - (-5) = 0 * (x - 6), which simplifies to y + 5 = 0, which is y = -5.
Formula for Slope:
[tex]\frac{y1 - y2}{x1 - x2}[/tex]
Usable with 2 points of the line given ((x1, y1) and (x2, y2))
Formula for Equation of the Line:
[tex]y - y1 = slope * (x - x1)[/tex]
Usable with the slope and a point given ((x1, y1))
Answer: AB is undefined (AB is not a relationship, slope is undefined (Vertical Line)) and CD is y = -5 (Horizontal Line)
