Is it possible for any angle A, sinA=7/5Explain.
Answer:
No
Step-by-step explanation:
note [tex]\frac{7}{5}[/tex] = 1.4
and sinA is defined for - 1 ≤ sinA ≤ 1
Thus sinA ≠ [tex]\frac{7}{5}[/tex]

evaluate f(6) when f(x) = 2x + 4
Answer:
16
Step-by-step explanation:
f(x) = 2x + 4
f(6) = 2(6) + 4
=> f(6) = 12 + 4
=> f(6) = 16
-3(x² +2x-3)+3(x²+4x)
6x + 9
I hope this helps!
Answer:
= 6x +9
Step-by-step explanation:
1. you need to multiply -3 by x² + 2x - 3
so you got -3x² -6x + 9
2. Then, you need to multiply 3 by (x²+4x)
= 3x² + 12x
3. -3x² - 6x + 9 + 3x² + 12x
4. then you need to solve with the same
= - 3x² + 3x²
= 0
= - 6x + 12x
= 6x
5. lastly you will got the answer.
# = 6x +9

which of the following situations describes a postive number
Answer:
B. Going up the elevator 14 floors
Step-by-step explanation:
Choice A can't be right because you are going below sea level (negative).
Choice C can't be correct either because the word "losing" let's you know that it's negative.
Choice D isn't right because if you are taking $20 from your checking account, it would be a negative number.

Answer:
-2, 1, 4, (4 + d) , (4+d+d) , (4+d+d)
We have to first get the common difference
[tex]d = a _{2} - a_{1} \\ d = 1 - ( - 2) \\ d = 1 + 2\\ d = 3[/tex]

Solve the following equation. Show your work for credit.
3х -40 = 1/2x + 35
Answer:
x=30
Step-by-step explanation:
Let's solve your equation step-by-step.
3x−40=12x+35
Step 1: Subtract 1/2x from both sides.
3x−40−12x=12x+35−12x
52x−40=35
Step 2: Add 40 to both sides.
52x−40+40=35+40
52x=75
Step 3: Multiply both sides by 2/5.
(2/5)*(5/2 x)=(2/5)*(75)
x=30

Part E
Now check your work by using the GeoGebra geometry tool to repeat parts A through D. Open GeoGebra, and complete each step below. If you need help, follow these instructions for using GeoGebra. You will take a screenshot of your work when you are through, so be sure to clearly label your construction as you work.
Plot points A, B, and C, and draw a polygon, ΔABC, through the points.
Draw a line perpendicular to AC¯ through point B.
Label the intersection of the line perpendicular to AC¯ through B and AC↔ point D.
Measure and display the slopes of AC↔ and BD↔.
Display the equations of AC↔ and BD↔ in the Algebra margin.
Measure and display the lengths of AC¯ and BD¯.
Calculate and display the area of ΔABC.
Take a screenshot showing the geometric construction and the Algebra margin, save it, and insert the image in the space below.
Part F
Compare the calculations displayed in GeoGebra with the calculations you completed in parts A through D. Look in the Algebra margin too. Do the results in GeoGebra match the results you obtained earlier? If not, where do the discrepancies occur? You might have to rearrange equations algebraically to determine whether two equations match.
Part G
You’ve seen two methods for finding the area of ΔABC—using coordinate algebra (by hand) and using geometry software. How are the two methods similar? How are they different? Why might coordinate algebra be important in making and using geometry software?

The sales of Horizon, a cell phone sales and service provider, were $127,693,100 last year. What is the value of the 6th digit in this number?
Answer:
600000
Step-by-step explanation:
Cuz it is in the 100000 spot
Answer:
600000
Step-by-step explanation:
Based on the place value system, the digits are ordered from the right to left. So the 6th digit is 6 located in the hundreds of thousands column. The value of the 6th digit is obtained by multiplying the digit by the value of it's place value column
i.e 6 * 100,000 = 600, 000
Ans: 600,000

Here’s why:
⸻⸻⸻⸻
There were $450 dollars deposited into a bank account. The total amount after it's been deposited is $512.⸻⸻⸻⸻
[tex]\rightarrow x + 450 = 512\\\\\rightarrow x + 450 - 450 = 512 - 450\\\\\rightarrow x = 62[/tex]

An equilateral triangle measures 5 by 3/8 cm on one side. What is the perimeter of the traingle
Step-by-step explanation:
in an equilateral triangle all 3 sides have the same length.
so, when one side measures 5 3/8 cm, then all 3 sides have the same length.
this "5 by 3/8 cm" phrasing is strange. normally that would be used for an area giving 2 dimensions. but here it is clearly meant to describe one dimension, length.
so, I can only assume this means the side is 5 3/8 cm long.
the perimeter of the triangle is simply the sum of all ways needed to walk around the whole triangle : the sum of all 3 sides.
we could do this 2 ways (1. convert 5 3/8 into one big fraction and do the calculation, 2. stay with 5 3/8 and do the calculations there).
I think 1. it's easier to understand and to also use it for other similar problems.
so,
5 3/8 = (5×8 + 3)/8 = (40 + 3)/8 = 43/8
we have 3 sides of equal length
Perimeter = 3×43/8 = 129/8 = 16 1/8 cm
One side of the equilateral triangle is given, then the perimeter of the triangle will be equal to 16. (1/8) or 129/8.
What is perimeter?The complete distance around a shape is referred to as its perimeter. It is any two-dimensional geometric shape's perimeter or outline length. Based on the measurements, the circumference of multiple figures may be equivalent.
As per the given data in the question,
One side of the triangle = 5 3/8
= 43/8
All the sides of the equilateral are equal, then,
Perimeter, P = 3 × side
P = 3 × 43/8
P = 129/8 or 16(1/8)

Can someone help me with this proportion? I'm really bad at math:
'Jill burns 200 calories in a 3/4 hour workout. How many calories will she burn in a 3 hour workout?'
Answer: 800 calories
Step-by-step explanation:
Let us set this up as a fraction
Firstly, convert 3/4 into a decimal
[tex]3 \div 4 = 0.75[/tex]
Now we can set up the fraction
Make sure to put the calories on the same side and hours on the same side as well. So it should be: [tex]\frac{200}{0.75}=\frac{x}{3}[/tex]
Then, solve
[tex]\frac{200}{0.75}=\frac{x}{3}[/tex]
The fractions are supposed to be proportional meaning, if the denominator is a certain number when solved, the numerator should be the same, if solve likely. let me show you:
Divide 3 by 0.75
[tex]0.75 \div 3 = 4[/tex]
Now since the number isn't found yet, we will use the opposite operation, which is multiplication, in this case.
Multiply 200 to 4
[tex]200 \times 4 = 800[/tex]
Therefore, she will burn 800 calories in a 3-hour workout.
