Answer:
D
Step-by-step explanation:
It is because you can see the line pass through the value 0 in x-axis while 6 in y-axis which gives the first coordinate (x,y) = (0,6) and the line also past through the value of 5 in x-axis and 1 in y-axis which gives the second coordinate is (1,5).
So it is true that the line did go through at points (0,6) and (1,5).

Answer:
81 sq.metreStep-by-step explanation:
So this shape is made up two geometrical shapes - Triangle and a Rectangle.
So we have to find the area of Rectangle and Triangle
Area of Rectangle =
[tex]l \times b[/tex]
If we apply this to the given diagram we get,
[tex]10 \times 6 \\ = 60[/tex]
Now we have to find the area of Triangle
Area of Triangle =
[tex] \frac{1}{2} \times b \times h[/tex]
If we apply this to the given diagram we get,
[tex] \frac{1}{2} \times 7 \times 6 \\ = \frac{1}{2} \times 42 \\ = 21[/tex]
So the total area of the given figure is 60 + 21 which is equal to 81 sq.metre
Answer:
[tex]81m^{2}[/tex]
Step-by-step explanation:
Area of rectangle =Length × Width
so Area of rectangle = 10 × 6=60[tex]m^{2}[/tex]
The base of triangle equals to the width of rectangle so,
Area of triangle =[tex]\frac{1}{2}[/tex]×7×6=21[tex]m^{2}[/tex]
Then add the two areas together so , 60+21=81[tex]m^{2}[/tex]

Step-by-step explanation:
Area of a trapezoid = 1/2(b1+b2)h
You add together the bottom and top bases, and then divide it in half to get the average. Then you multiply it by the height.
1/2(12+6)6
1/2(18)6

The top of a 230 foot vertical tower is to be anchored by cables that make an angle with a measure of 50 degrees with the ground.
How long must each cable be? ____ feet
How far from the base of the tower should the anchors be placed? _____ feet
9514 1404 393
Answer:
cable length: 300.2 ftanchor distance: 193.0 ftStep-by-step explanation:
The side given is opposite the given angle. We want to find both the hypotenuse and the adjacent side in the right triangle that models the geometry.
Sin = Opposite/Hypotenuse
sin(50°) = (230 ft)/h
h = (230 ft)/sin(50°) ≈ 300.24 ft
The length of the cable must be about 300.2 feet.
__
Tan = Opposite/Adjacent
tan(50°) = (230 ft)/d
d = (230 ft)/tan(50°) ≈ 192.99 ft
The cable must be anchored about 193.0 ft from the tower.

Can someone please help me? I am trying to help my son. Here is the problem:
Catherine is hanging a string of lights 40 feet long around the three sides(two on the width and one on the length) of her rectangle patio, which is adjacent to her house. The length of her patio, the side of the house, is eight feet shorter than six times the width. Find the length and the width of the patio.
Thanks everyone!!
Answer:
Step-by-step explanation:
x = width
6x - 8 = length
2x + 6x - 8 = 40
8x = 48
width = 6 feet
length = 28 feet

2. Define any variables and tell the slope and y-intercept of the situation. Then, write an equation to represent
the situation.
An electrician charges $75 for a service call and $25 for each hour they are on the job. If the electrician spends x hours at a house, what will the total charge, C(x) be?
Answer:
x=number of hours
c(x)= 25x+75
y-intercept= (0, 75)
Equation= y=25x+75
Slope= 25
Step-by-step explanation:
75 would be the y intercept(constant) because that's the initial charge for a call.
25 would be the coefficient for x because the hour you spend on the call varies.
The slope is how steep the line is, in this case it is 25.
x is the number of hours because that is the time that varies.

what is the slope of the line shown?
Answer:
I can's make out the line, but, you can plot two points, (try to make them whole numbers ie (3,6), (4,8)), subtract the point with the smallest x value from the other point ((4,8)-(3,6)=(1,2)) Divide the new y, by the new x (2/1), and you have your slope.

Answer:
Step-by-step explanation:
The Medassist Pharmaceutical Company uses a machine to pour cold medicine into bottles in such a way that the standard deviation of the weights is 0.15 oz. A new machine is tested on 71 bottles, and the standard deviation for this sample is 0.12 oz. The Dayton Machine Company, which manufactures the new machine, claims it fills the bottles with less variation. At the 0.05 significance level, test the claim made by the Dayton Machine Company.
Answer:
hello some part of your question is missing below is the missing part
If Dayton's machine is being used on a trial basis, should its purchase be considered? C.V.(S) = Test Statistic= P-Value= Decision: Conclusion:
answer :
i ) Cv(s) = 51.739
ii) T = 44.8
iii) p-value = 0.0082
iv) we do not fail to reject H0 ( since p-value < 0.05 )
v ) The new machine fills the bottles with a lesser variation
Step-by-step explanation:
we will test the hypothesis in regards to the standard deviation of the population
The hypothesis are
H0 : б = 0.15
Ha : б < 0.15
hence at ∝ = 0.05 where n = 71
i) critical point for left sided test = [tex]x^2_{1-\alpha } , n - 1[/tex]
hence Cv(s) = 51.739
ii) Test statistic = T = ( n - 1 ) s^2 / б^2
s = 0.12 , n = 71 , б = 0.15
hence T = 44.8
iii) P-value = p ( [tex]x^{2} _{70}[/tex] < 44.8 ) = 0.0082
iv ) Decision : we do not fail to reject H0 ( since p-value < 0.05 )
v ) conclusion : The new machine fills the bottles with a lesser variation

What is the error in this equation for a trigonometric ratio? Explain the error in full sentences and give a corrected ratio. (5 points)
Answer:
[tex]\cos\ A = \frac{2}{4.5}[/tex]
Step-by-step explanation:
Given
[tex]sin\ A = \frac{2}{4.5}[/tex]
See attachment
Required
Explain and correct the error
The error in the equation is that: the formula of cosine of angle A is used to calculate the sine of angle A.
The ratio can be corrected as by using:
[tex]\cos\ A = \frac{Adjacent}{Hypotenuse}[/tex]
[tex]\cos\ A = \frac{AC}{AB}[/tex]
[tex]\cos\ A = \frac{2}{4.5}[/tex]

Which of the following are possible measures for the angle shown? Select all that apply.
Answer:
-510 degrees and -210 degrees :)
Step-by-step explanation:
An angle is a figure created by two rays. The measure of the angle can be written as 150° or -210°.
What is an angle?An angle is a figure created by two rays, known as the sides of the angle, that have a common terminus, known as the vertex of the angle. Angles created by two rays lie in the plane containing the beams.
The measure of the angle measured from the positive x-axis in an anticlockwise direction will be,
[tex]\theta = 180^o-30^o = 150^o\\\\[/tex]
The measure of the angle measured from the positive x-axis in clockwise direction will be,
[tex]\theta = 180^o+30^o = -210^o[/tex]
Hence, the measure of the angle can be written as 150° or -210°.

and the second one is:
10
The first one is asking for an expression that is 8 more than x. The word more always implies adding. So the expression would be : x + 8
The second one just wants you to substitute 2 into the equation you made in the first one. So 2 + 8 is 10
