Answer:
x = 10.2
Step-by-step explanation:
Formula:
a² + b² = c²
16² + b² = 19²
256 + b² = 361
b² = 361 - 256
b² = 105
b = 10.2
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.

What is the equation of the line that passes through the point (8,9) and has a y-intercept of -3?
Answer:
y=3x/2-3
Step-by-step explanation:
y=mx+c
9=m(8)-3
9+3=8m
12=8m
m=12/8
m=3/2

Answer:
C
Step-by-step explanation:
slope is the change of y / change of x
.
we can pick any points and find the changes in y and x
lets pick (0 , 0) and (5 , 6) .
the change of y = 6-0 = 6.
the change of x = 5-0 = 5.
so the slope of the line is 6/5

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

Pair 1 and pair 3 have congruent polygons.
What is a Congruent Polygon?A polygon is said to be congruent if it has the same shape, sides that are the same length, and internal angles as the polygon it is being compared to. The criterion is satisfied if all of the congruent shapes are of the same type.
Pair 1: The polygons are identical in size and shape.
Pair 2: The polygons are identical in shape but vary in size.
Three: The polygons are the same size and shape.
Pair 4: The polygons are identical in shape but vary in size.
Here, pair 1 and pair 3 have congruent polygons.

A teacher buys a fruit cup for $1.50 and a calculator for $13.75 for each student in their classroom. The teacher spends a total of $579.50 for all of the fruit cups and calculators.
How many students are in the teacher's class? Please help I need to finish this ASAP
Answer:
1.50 + 13.75 = 15.25
15.25 x 579.50 = 38
ok so basically you take the total and divide it by the total of one student!! :)
answer is: 38

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]

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
