Please help. What is the area of the rhombus in simplest radical form? The figure is not drawn to scale.
The area of the rhombus in the simplest radical form is 87 units²
Properties of a rhombusAll the sides are equal.Opposite sides are parallel.Diagonals are perpendicular to each other.Opposite angles are equal.Therefore,
area of the rhombus = ab / 2
where
a and b are the diagonalsTherefore,
tan 60 = x / 5
x = 5 tan 60
x = 8.66025403784
x = 8.7 units
area of the rhombus = (8.7 ×2) (5 × 2) / 2 = 17.4 (10) / 2 = 87 units²

This is a right isosceles triangle!
Answer:
c x=8.7
Step-by-step explanation:
length of the 2 shortest sides squared and the length of the longest side square would be x^2+25=100
x^2=75
which would be x=8.7

The equation d = 11 cosine (startfraction 8 pi over 5 endfraction t) models the horizontal distance, d, in inches of the pendulum of a grandfather clock from the center as it swings from right to left and left to right as a function of time, t, in seconds. according to the model, how long does it take for the pendulum to swing from its rightmost position to its leftmost position and back again? assume that right of center is a positive distance and left of center is a negative distance.
The time that is taken for the pendulum to swing from its rightmost position to its leftmost position and back again is 1.25 seconds
Calculations and Parameters:Given that this is a cosine equation,
At maximum, Cos (0) =1
At minimum, Cos (π) = -1.
Hence,
At the maximum:
8π/5 t = 0t = 0At the minimum:
8π/5 t = πt = 5/8t = 0.625Given that the time taken from max to min is 0.625 and also to min to max is also 0.625,
The total time taken would be:
0.625 + 0.625 = 1.25s

5x – 4y = 12
Answer:
[tex]y =\frac{5}{4}x+ ( -3)[/tex]
Step-by-step explanation:
Step 1: Subtract 5x from both sides
[tex]5x - 4y = 12[/tex]
[tex]5x - 5x - 4y = 12 - 5x[/tex]
[tex]-4y = 12 - 5x[/tex]
Step 2: Divide both sides by -4
[tex]\frac{-4y}{-4} = \frac{12}{-4} - \frac{5}{-4}x[/tex]
[tex]y =\frac{5}{4}x+ ( -3)[/tex]

A is directly proportional to B. When A = 12, B = 3
Find the value of A when B = 3
Answer:
A = 12
Step-by-step explanation:
We can define ratio a to b as 12:3. If we are finding the value of A when B is 3, we go to the ratio. The ratio says that when B is 3, A is 12. Therefore, A is 12.
Answer:
A = 12
Explanation:
Given:
A ∝ B
set "k" constant
A = k(B)
Find "k"
12 = k(3)
k = 4
Then find A when B = 3
A = k(B)
insert values found
A = 4(3)
A = 12

f(x) = x2. What is g(x)?
Answer:
A. g(x) = -x^2 - 3.
Step-by-step explanation:
If we reflect f(x) over the x -axis we get -f(x) which is the mirror image of f(x)
To get g(x) we then translate the image 3 units down,
g(x) = -x^2 - 3.

A window is shaped like a parallelogram
The base of the window is 14.25 inches.
The area is 356.25 square inches. What
is the height of the window?
Answer:
Do the area divided by the base on a calculator for the answer
Answer:
Height of the window= 25 inches
Step-by-step explanation:
Area of a parallelogram : base * height (of the side taken as base)
so height = area/base = 356.25/14.25 = 25 inches

Javier has four cylindrical models. The heights, radii, and diagonals of the vertical cross-sections of the models are shown in the table. A cylinder. Model 1 radius: 14 cm height: 48 cm diagonal: 50 cm Model 2 radius: 6 cm height: 35 cm diagonal: 37 cm Model 3 radius: 20 cm height: 40 cm diagonal: 60 cm Model 4 radius: 24 cm height: 9 cm diagonal: 30 cm In which model does the lateral surface meet the base at a right angle? Model 1 Model 2 Model 3 Model 4
The model in which the lateral surface meets the base at right angle is : Model 1.
What is a lateral surface?The lateral surface of an object is all surfaces of that object excluding its base and top.
Analysis:
To know the exact model, we check for the models in which their dimensions form a Pythagorean triplet otherwise a right-angled triangle.
For Pythagorean triplet, the square of the diagonal must be equal to the sum of squares of the other two sides.
Model 1
Diagonal = 50cm, radius = 14cm, lateral height = 48cm
[tex](50)^{2}[/tex] = [tex](14)^{2}[/tex] + [tex](48)^{2}[/tex]
2500 = 196 + 2304
2500 = 2500. Forms Pythagorean triplet
Model 2
Diagonal= 37cm, radius = 6cm lateral height = 35cm
[tex](37)^{2}[/tex] = [tex](35)^{2}[/tex]+ [tex](6)^{2}[/tex]
1369 = 1225 +36
1369 [tex]\neq[/tex] 1261
Model 3
Diagonal = 60cm, radius = 20cm lateral height = 40cm
[tex](60)^{2}[/tex] = [tex](20)^{2}[/tex] + [tex](40)^{2}[/tex]
3600 = 400 + 1600
3600 [tex]\neq[/tex] 2000
Model 4
Diagonal = 30cm, radius = 24cm, lateral height = 9cm
[tex](30)^{2}[/tex] = [tex](24)^{2}[/tex] + [tex](9)^{2}[/tex]
900 = 576 + 81
900 [tex]\neq[/tex] 657
Therefore the lateral surface model 1 meets the base at right angle
In conclusion, the lateral surface of model 1 meets the base at right angles as the dimensions form a right-angled triangle.

what is the solution in the equation X +3 equals 27
A 24
B 30
C 81
D 90
A+B+A+D=32
What does A+B=?
The value of A+B is 16
This question is related to division.To solve it, we will: divide the number after the equality, by the total number of variables (letters) that have.
A + B + A + D = 32
32 ÷ 4 = 8
< We know that the value of each variable is 8. So, to find the value of A + B, let's just add their respective values.
A + B
8 + 8 = 16
So, the value of A + B will be 16
Tom volunteered 1 out of the last 12 days at the school store. Which shows the decimal form of this ratio?
Answer:
0.0833
Step-by-step explanation:
1 out of 12 can be written as a fraction 1/12
Now we convert the fraction to a decimal with division. Using long division the 12 goes outside the division symbol and 1 on the side. 12 doesn't go into 1 so we add a decimal to the answer and a 0 after the 1. 12 doesn't go into 10 so we add another 0. 12 goes into 100 8 times. 8 goes on top after 0.08 and then we finish the long division. We would have 4 remaining. Add another 0. 12 goes into 40 3 times. This is then where the division becomes repetitive. With more threes. Depending on where youryou're supposed to Round to the answer is 0.0833

What is the simplified value of the exponential expression 16 superscript one-fourth? 2 4
The simplified value of the exponential expression is 2.
How to get the simplified expression?
Here we need to simplify the expression:
[tex]16^{1/4}[/tex]
First, you need to remember that:
[tex]\sqrt[n]{x} = x^{1/n}[/tex]
Then we can just write:
[tex]16^{1/4} = \sqrt[4]{16}[/tex]
And now, you can remember that:
2*2 = 4
Then:
2*2*2*2 = 4*4 = 16
From this, we can conclude that:
[tex]2^4 = 16\\\\\sqrt[4]{16} = 2[/tex]
