Find the exact value of cos 30° in simplest form with a rational denominator.
Answer:
[tex]\cos(30) = \frac{\sqrt3}{2}[/tex]
Step-by-step explanation:
Required
Exact value of [tex]\cos(30)[/tex]
[tex]\cos(30)[/tex] is calculated from an equilateral triangle, divided into with the following dimensions
[tex]Hypotenuse = 6[/tex]
[tex]Adjacent = 3[/tex]
[tex]Opposite = 3\sqrt 3[/tex]
So:
[tex]\cos(30) = \frac{3\sqrt3}{6}[/tex]
[tex]\cos(30) = \frac{\sqrt3}{2}[/tex]
Need help ASAP! What is the value of X? :)
Answer:
x = 46
Step-by-step explanation:
Since the angle that is not marked is a vertical angle, is must be the same in each triangle
The sum of each triangle is 180, set them equal and subtract the same angle from each side, this leaves the equation
53+85 = x+92
138 = x+92
138-92 =x
46 =x

In the accompanying diagram, triangle ABC is similar to triangle RST, BC= 12, AC=15, and ST= 8. Find RT.
Answer:
10
Step-by-step explanation:
ABC is similar to RST,
so BC is corresponding to ST, and AC is corresponding to RT
BC=12 and ST=8
so the scale factor from RST to ABC is 1.5 and the scale factor from ABC to RST is 2/3 because 12*(2/3) is 8, and 8*1.5 is 12.
now apply this to AC to find RT
AC=15
15*(2/3)=10
10*1.5=15
RT =10
The measures of the angles in triangle UVW are shown in the diagram below.
Answer:
(B) 39°
Step-by-step explanation:
30° + 24° + (3x -9°) = 180°
3x = 180° - 30° - 24° + 9°
3x = 117°|:3
x = 39°

Answer:
384 square yards
Step-by-step explanation:
The area of a rectangle is given by the formula ...
A = LW . . . . . where L and W stand for Length and Width
Using the given dimensions, you find the area to be ...
A = (24 yd)(16 yd) = 24×16 yd² = 384 yd²
The area of the figure is 384 square yards.
The function f(x) is shown in this graph.
(0,2)
The function g(x) = -5x - 6. Compare the slopes.
A. The slope of f(x) is the same as the slope of g(x).
B. The slope of f(x) is undefined, and the slope of g(x) is negative.C. The slope of f(x) is greater than the slope of g(x).D. The slope of f(x) is less than the slope of g(x).
Answer:
D. The slope of f(x) is less than the slope of g(x).
Step-by-step explanation:
✔️Slope of f(x):
Using two points on the line, (0, 2) and (1, -1),
Slope (m) = change in y/change in x
Slope (m) = (-1 - 2)/(1 - 0) = -3/1 = -3
Slope of f(x) = -3
✔️Slope of g(x) = -5x - 6:
The slope of g(x) is -5.
Therefore f(x) has a lesser absolute slope value (3) compared to the absolute slope value of g(x) (5).
Thus, D. the slope of f(x) is less than the slope of g(x).
At a pizza restaurant, a personal pizza has a radius of 10 centimeters and costs $5. Another restaurant takes a pizza with radius 30 centimeters, cuts it into 8 slices of equal area, and charges $5 per slice. Which is a better deal? Explain your reasoning.
Answer:
Remember that the area of a circle of radius R is given by:
A = pi*R^2
pi = 3.14
We know that:
Personal Pizza: radius = 10cm
price = $5
The area of pizza that you are getting is:
A = 3.14*(10cm)^2 = 314 cm^2
In the other case, we have a pizza with radius of 30 cm, cutted into 8 slices, such that each slice costs $5.
Then, if yo pay $5, the area of pizza that you get is an eight of the area of a circle of radius 30cm
This is:
A' = (1/8)*(3.14*(30cm)^2) = 353.25 cm^2
We can see that in the second case the area is larger, then the second option is the better deal, as you are getting a larger pizza area for the same price.
A quality control inspector has drawn a sample of 10 light bulbs from a recent production lot. Suppose 20% of the bulbs in the lot are defective. What is the probability that exactly 6 bulbs from the sample are defective? Round your answer to four decimal places.
Answer:
33.33 repeating percent.
Step-by-step explanation:
So using the 20 percent, we can guess there will be 2 bulbs that are defective in the sample. So 2/10. But we are guessing there will be 6;6/10. We alreadly know the proablity of that is low. To be exact 2/6 (as they are both over ten we can get rid of that) or 1/3, or 33.333 repeating percent.
Hope this helps!
instructions: Find the slope of the line through the points (6, 16) and \ -6,4) Make sure to simplify fractions and enter your answers with a foward slash (i.e. "/"). If the slope is undefined enter "undefined."
9514 1404 393
Answer:
1
Step-by-step explanation:
The slope formula is useful for this.
m = (y2 -y1)/(x2 -x1)
m = (4 -16)/(-6 -6) = -12/-12
m = 1
The slope of the line through the given points is 1.
sum of the arithmetic sequence 8,14,20 if there are 24 terms
Answer:
1,848
Step-by-step explanation:
Find the arithmetic pattern:
*Arithmetic means addition or subtraction*
To get from 8 to 14, we must add 6.
To get from 14 to 20, we must add 6.
The arithmetic pattern is 6.
List the rest of the terms (24 terms total):
8, 14, 20, 26, 32, 38, 44, 50, 56, 62, 68, 74, 80, 86, 92, 98, 104, 110, 116, 122, 128, 134, 140, 146
Formula:
Sn = n (a1 + an/2)
a1 = first term
an = last term
n = number of terms
Sn = 24 (8 + 146/2)
Sn = 24 (154/2)
Sn = 24 (77)
Sn = 1,848
Answer:
1848
Step-by-step explanation:
a=8
d=14-8=6
n=24
[tex]S_{n}=\frac{n}{2} [2a+(n-1)d]\\S_{24}=\frac{24}{2} [2 \times 8+(24-1)6]\\=12[16+138]\\=12 \times 154\\=1848[/tex]
Find the standard form of the equation of the circle with endpoints of a diameter at the points (7,8) and (-3,6). Type the standard form of the equation of this circle
Answer:
The equation of the circle is [tex](x - 2)^2 + (y - 7)^2 = 21[/tex]
Step-by-step explanation:
Equation of a circle:
The equation of a circle, with center [tex](x_0,y_0)[/tex] and radius r is given by:
[tex](x - x_0)^2 + (y - y_0)^2 = r^2[/tex]
Distance between two points:
Suppose that we have two points, [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex]. The distance between them is given by:
[tex]D = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
Diameter at the points (7,8) and (-3,6).
The diameter is the distance between these two points, so:
[tex]D = \sqrt{(-3-7)^2+(6-8)^2} = \sqrt{104}[/tex]
Radius is half the diameter, so:
[tex]r = \frac{\sqrt{104}}{2} = \frac{\sqrt{104}}{\sqrt{4}} = \sqrt{\frac{104}{4}} = \sqrt{21}[/tex]
So
[tex]r^2 = (\sqrt{21})^2 = 21[/tex]
Center:
Midpoint of the diameter, which is the mean of the coordinates. So
[tex]x_0 = \frac{7 - 3}{2} = \frac{4}{2} = 2[/tex]
[tex]y_0 = \frac{8 + 6}{2} = \frac{14}{2} = 7[/tex]
Then
[tex](x - 2)^2 + (y - 7)^2 = 21[/tex]

A factory that manufactures screws is performing a quality control experiment. Each object should have a length of no more than centimeters. The factory believes that the length of the screws exceeds this value and measures the length of screws. The sample mean screw length was centimeters. The population standard deviation is known to be centimeters.
1. What is the null hypothesis?
2. What is the alternative hypothesis?
Answer:
a) Null Hypothesis: length of each screw is less than 14 centimeters
b) Alternate Hypothesis: length of each screw is equal to or greater than 14 centimeters
Step-by-step explanation:

The population standard deviation is known to be centimeters.
1. What is the null hypothesis?
2. What is the alternative hypothesis?
Solution :
The null hypothesis is basically the problem statement that needs to be tested.
Alternate hypothesis is opposite of that of null hypothesis
a) Null Hypothesis: length of each screw is less than 14 centimeters
b) Alternate Hypothesis: length of each screw is equal to or greater than 14 centimeters
