Find the value of 2abcosC.
Answer:
7
Step-by-step explanation:
a=2
b=2
c=1
2ab cos C=a²+b²-c²=2²+2²-1²=4+4-1=7
Answer:
C
Step-by-step explanation:
Given
a² + b² - 2abcosC = c² ( subtract c² from both sides )
a² + b² - c² - 2abcosC = 0 ( add 2abcosC to both sides )
a² + b² - c² = 2abcosC
Here a = 2, b = 2, c = 1 , then
2² + 2² - 1² = 2abcosC
4 + 4 - 1 = 2abcosC , then
2abcosC = 7 → C

Help! Geometry Triangle Congruence
Answer:
Step-by-step explanation:
Thank your for revising and improving the image.
Assuming DF is a straight line,
Given E is the mid-point of DF
mCE = mGF
CE || GF
Then
mDE = mEF (E midpoint of DF)
Angle DEC = Angle EFG (corresponding angle, DF transversal of parallel lines CE and GF)
mCE = mGF (given)
Then triangles DCE and EGF are congruent by reason SAS (side-angle-side)

Answer:
IDR 3,651.04
Step-by-step explanation:
4x24=96
96x2,400=230,400
230,400+50,000=280,400
280,400x1.25=350,500
350,500/96=3,651.04
IDR 3,651.04
Answer:
3651 IDR
Step-by-step explanation:
I need to make some assumptions, as the problem description is sometimes too vague.
I assume the delivery charge to cover all 4 boxes as one lump sum.
4 boxes with 24 pouches each.
=> Roma has 96 pouches total.
each pouch cost 2400. that is in total
96×2400 = 230400 IDR
then there is the delivery charge of 50000 for everything.
so, the total costs for Roma are
230400 + 50000 = 280400 IDR
25% profit means that the total sales (assuming all pouches are sold) is 25% higher than the costs.
profit = 280400 + 25%
25% is 1/4 of the total (as 25%×4 = 100%).
25% = 280400 / 4 = 70100.
so, in order to make 25% profit the total sales price (for all pouches sold) has to be
280400 + 70100 = 350500 IDR
now, we have 96 pouches. after selling all 96 pouches we need to have an income of 350500 IDR.
the price for each pouch has to be an equal share of the 350500.
pouch price = 350500 / 96 = 3651 IDR.
A normal distribution has a mean of 15 and a standard deviation of 2. Find the value that corresponds to the 75th percentile. Round two decimal places
Answer:
16.35
Step-by-step explanation:
Using an inverse normal distribution, we can calculate the z score given the percentile, which can then be used to find our value.
First, we can use an inverse normal distribution calculator to figure out that the z score given the 75th percentile is 0.674.
Next, we know that the z score is (observed value - mean) / standard deviation. We can plug our values in to get
[tex]\frac{x-15}{2} = z\\\frac{x-15}{2} = 0.674\\x-15 = 0.674 * 2\\x = 0.674 * 2 + 15\\x= 16.348[/tex]
Rounding, we get x = 16.35 as our answer

Find the value of x. Round to the nearest tenth.
Answer:
10.
Step-by-step explanation:
According to Pythagoras,
14^2 = 10^2 + x^2
196 = 100 + x^2
x^2 = 196-100
x^2 = 96
x = 9.8
x = 10 (nearest tenth)

During the kickoff at a local high school football game, a football is placed onto a tee to a height of 0.125 feet above the ground. The football is kicked with an initial velocity of 80 feet per second. If the ball is caught at a height of 5 ft, approximately how long did it remain in the air? Round to the nearest hundredth of a second. Answer the question and make an equation
Answer:
Time in air is 7.5 s.
Step-by-step explanation:
initial height, h = 0.125 feet
initial velocity, u = 80 ft/s
final height, h' = 5 ft
acceleration due to gravity, g = 32 ft/s^2
Let the time is t to reach the maximum height.
v = u - gt
0 = 80 - 32 t
t = 2.5 s
Let the time is t' from top to ground.
[tex]s = u t + 0.5 gt^2\\\\5 = 80 t - 16 t^2\\\\16 t^2 - 80 t + 5 = 0 \\\\t = \frac{80\pm\sqrt{6400 - 320}}{32}\\\\t = \frac{80\pm78}{32}\\\\t = 5 s or 0.0625 s[/tex]
So the tie is 5 s
The time in air is
T = 2.5 + 5 = 7.5 s

a man in a boat rowing from lighthouse whose height is 200m it takes 2 minutes to change the angle of elevation of 60 degree to 45 degree find speed of boat
Answer:
Step-by-step explanation:
I attached a picture below of what this situation looks like. As you can see, it is a right triangle problem. In order to solve for the speed of the boat, we first need to find out the difference between his distances when the angle is 60 and when it is 45. That's the same thing as finding x and y then subtracting. To find x:
[tex]sin60=\frac{200}x}[/tex] so
x = 231 meters (I rounded to the nearest whole numbers in this problem.
To find y:
[tex]sin45=\frac{200}{231+y}[/tex] so
[tex]y=\frac{200}{sin45}-231[/tex] and
y = 52.
The distance between the angles 60 and 45 as 52 meters, and it took him 2 minutes to travel that 52 meters. Assuming that his rate doesn't change, he can travel 52/2 meters per minute, or 26 meters per minute.

Let h(x) = x*2 + kw - 8. If h(-1) = -5, what is the value of h(4)?
Help
Answer:
h(4) = 0
Step-by-step explanation:
Hoping its ' kx '
[tex]h(x) = x^2 + kx -8 \\\\h(-1) = (-1)^2 + k(-1) - 8\\\\-5 = 1 - k -8\\\\-5 = -k -7\\\\-5 + 7 = -k\\\\2 = -k\\-2 = k[/tex]
Now we have k = -2. We will find h(4).
[tex]h(4) = (4)^2 + (-2)(4) - 8 = 16 -8 - 8 = 0[/tex]
Answer:
h(4) = 0
Step-by-step explanation:
GIVEN :-
A quadratic function h(x) = x² + kx - 8h(-1) = -5TO FIND :-
Value of h(4)SOLUTION :-
To find the value of h(4) , you need to find 'k' first by using the given facts.
[tex]h(-1) = (-1)^2 + k(-1) - 8 = -5[/tex]
[tex]=> 1 - k - 8 = -5[/tex]
[tex]=> -k - 7 = -5[/tex]
Add both the sides by 7.[tex]=> -k - 7 + 7 = -5 + 7[/tex]
[tex]=> -k = 2[/tex]
Multiply both the sides by -1.[tex]=> -k(-1) = 2(-1)[/tex]
[tex]=> k = -2[/tex]
Putting the value of k,
[tex]h(4) = (4)^2 + (-2)(4) - 8[/tex]
[tex]= 16 - 8 - 8[/tex]
[tex]= 16 - 16[/tex]
[tex]= 0[/tex]

9514 1404 393
Answer:
C) 7
Step-by-step explanation:
We have ...
TS +SR = 19
SR +RQ = 13
Adding these two equations together, we have ...
TS +2·SR +RQ = 19 +13 = 32
We also have ...
TS +SR +RQ = 25
Subtracting this from the equation above, we have ...
(TS +2·SR +RQ) -(TS +SR +RQ) = 32 -25
SR = 7

Ricardo has 32 books to put on for shelves you put the same number of books on each shelf how many books does Ricardo put on a Shelf
Answer: Ricardo put 8 books on each shelf.
Step-by-step explanation:
Given: Number of books = 32
Number of shelves = 4
We use division operation to divide an amount into different sections equally.
By division operation,
The number of books put on each shelf = (32) ÷ 4
i.e. The number of books put on each shelf = 8
Therefore, Ricardo puts 8 books on each shelf.
