Step-by-step explanation:
Cos(Ф) = Adj / Hyp
Cos(Ф) = Adj / 5
use Pythagoras's
[tex]5^{2}[/tex] = [tex]2^{2}[/tex] +[tex]x^{2}[/tex]
25 - 4 = [tex]x^{2}[/tex]
21 = [tex]x^{2}[/tex]
[tex]\sqrt{21}[/tex] = x
Cos(Ф) = [tex]\sqrt{21}[/tex] / 5

The height of a penny t seconds after being dropped down a well is given by the product
of (10 - 3t) and (10+ 31). Find the product and simplify.
Is it
A.)A=35,B=34
B.)A=28,B=34
C.)A=35,B=28
D.)A=34,B=28
Answer:
D. A=34, B=28
Step-by-step explanation:
In the bulletin points, it says that seconds 3-5 are decreasing. That means that those heights can't be higher than second 2 (34). The only option that works is option D.
----------------------
Option A is incorrect because it starts with 35ft which is higher than second 2(34) so that is automatically wrong.
Option B is incorrect because it is increasing instead of decreasing.
Option C is incorrect for the same reason as Option A: it starts with 35ft.
---------------------
Therefore, the only correct option is Option D.

What are the properties of the circle?The circumference, which is the distance around the object, the diameter, which is the length of a circle measured from one end to the other and passing through its center, and the radius, which is equal to half of the diameter, are the three key characteristics.
The general coordinate equation of a circle is:
(x-h)² + (y - k)² = r²
Where,(h, k) is the center of a circle, "r" is the radius of the circle.
Given, a figure of the circle that gives the center of the circle is B.
Since, the Centre angle is twice the size of the angle of the circumference, made by the same arc.
Since both angles, ∠ABC and ∠ADC are made by the same arc AC.
Thus,
The angle made on the center = 2 * the angle made on the circumference,
The angle made on centre = 2 * 61
The angle made on center = 122°
Therefore, The measurement of angle ABC is 122°.

b) Is the image of the dilation a reduction or an enlargement of the original figure? Explain.
c) What is the scale factor? Explain
Answer:
a)ABC ≅ A'B'C' (SSS) b) Enlargement c) Scale factor = 4
Step-by-step explanation:
a) ABC ≅ A'B'C' (SSS)
b) The figure is going through an enlargement, this is evident as the figures have a scale factor of 4. If we were to put them into a fraction like this -
6/24=12/48=15/60
The figures are getting bigger, so they are going through an enlargement.
c) To find the scale factor of like done above, we could put them into a ratio.
6/24=12/48=15/60
Which would result in the scale factor of 4.

How many different triangles can you make if you are given these two lengths for sides?
The number of triangles is an illustration of Triangle Inequalities theorem
There are infinitely many triangles that can be made given two side lengths
How to determine the number of triangles?The side lengths of two sides are given as 18 inches and 25 inches.
Assume the third side of the triangle is x
Using the Triangle Inequalities theorem, we have:
a+b > cb+c > a,c+a > bSo, we have:
x +18 > 25
x > 7
x + 25 > 18
x > -7.
18 + 25 > x
x < 43.
Ignore the negative value.
So, we have the solution set to be 7 < x < 43.
This means that the third side can take any value between 7 < x < 43.
Hence, there are infinitely many triangles.

a. how much grape juice would you need to mix with 15/4 quarts of sparkling water
b. how much of each ingredients would you need to make 100 quarts of punch
Answer:
You would need 18 quarts of sparkling water to mix with 9 quarts of grape juice
Step-by-step explanation:
1 1/2 ---------> 3/4
x --------------> 9
We clear the value of x:
x = ((9) / (3/4)) * (1 1/2)
Rewriting we have:
x = ((9) * (4/3)) * (1 1/2)
x = (36/3) * (1 1/2)
x = (12) * (1 1/2)
x = (12) * (3/2)
x = 18

A grocery store collected sales data. It found that when customers buy less bread, they tend to purchase more rice. What can we conclude?
Answer:
There is a correlation between amount of bread bought and amount of rice purchased. However, there is no causation. This is because there is an increase in the amount of rice purchased with a decrease in the amount of bread bought.
Step-by-step explanation:
We see that there is a correlation between the amount of bread and the amount of rice bought .
When the bread is bought the amount of rice drops and when the amount of bread is decreased the amount of rice increases.
There is no causation meaning there is no direct affect of buying more bread or rice.Buying of rice does not directly cause the purchase of bread.
Hence there is correlation but not causation.
Correlation and causation can occur at the same time when one event causes the other.
Someone answer this please
Answer:
x = -47/3
Step-by-step explanation:
R = 3x + 9y
7 = 3x + 9(6)
7 = 3x + 54
-47 = 3x
x = - 47/3
Can't be reduced because 47 is prime
Answer:
x= -47/3
Step-by-step explanation:
So the information we already have is
7 = 3x + 9 * 6
9 * 6 = 54
now it is
7 = 3x + 54
The equation can also be
3x + 54=7
First subtract 54 from both sides
3x + 54 - 54= 7 - 54
3x= -47
Then divide both sides by 3
3x/3= -47/3
x= -47/3

Trevor is walking at the rate of 6 kilometers per hour. How many meters does Trevor walk in a minute?
Answer:
Trevor walks 100 meters in a minute.
Step-by-step explanation:
This question can be solved by proportions.
Trevor is walking at the rate of 6 kilometers per hour.
Each kilometer has 1000 meters, so he walks 6*1000 = 6000 meters per hour.
How many meters does Trevor walk in a minute?
An hour has 60 minutes.
6000/60 = 600/6 = 100
Trevor walks 100 meters in a minute.

The equation represents a circle is option (A) (x+2)^2 +(y-3)^2 = 72 is the correct answer.
What is a circle?A circle is a collection of all points in a plane which are at a constant distance from a fixed point. A circle is a round-shaped figure that has no corners or edges.
For the given situation,
The center of the circle, (h,k) = (-2,3)
The point on the circle, (x,y) = (4,-3)
The radius of the circle is
[tex]r=\sqrt{(h-x)^{2} +(k-y)^{2} }[/tex]
⇒ [tex]r=\sqrt{(-2-4)^{2} +(3-(-3))^{2} }[/tex]
⇒ [tex]r=\sqrt{6^{2}+6^{2} }[/tex]
⇒ [tex]r=\sqrt{72}[/tex]
The formula of equation of circle is
[tex](x-h)^{2}+(y-k)^{2}=r^{2}[/tex]
The circle has the center (h,k) = (-2,3) and radius is √72,
⇒ [tex](x-(-2))^{2}+(y-3)^{2}=(\sqrt{72} )^{2}[/tex]
⇒ [tex](x+2)^{2}+(y-3)^{2}=72[/tex]
Hence we can conclude that the equation represents a circle is option (A) [tex](x+2)^{2}+(y-3)^{2}=72[/tex] is the correct answer.
