Answer:

(1+sin2A+cos2A) ^2=4cos^2A(1+sin2A)

Step-by-step explanation:

Here,

L.H.S=(1+sin2A+cos2A)^2

=(1+2sinAcosA+2cos^2A-1)^2

=(2sinAcosA+2cos^2A)^2

={2cosA(sinA+cosA)}^2

=4cos^2A(sinA+cosA)^2

=4cos^2A(sin^2A+2sinA.cosA+cos^2A)

=4cos^2A(sin^2A+cos^A+2sinAcosA)

=4cos^2A(1+sin2A)

=R.H.S

Hence,L.H.S=R.H.S.

(1+sin2A+cos2A)^2=4cos^2A(1+sin2A).

proved.

Answer:

Y=45

Step-by-step explanation:

Y=2xz+x+z

Y=2×3×6+3+6

Y=36+9

Y=45

Answer:

- X + Y = -4  is the standard form

Y =1X  -4  is the  slope intercept form

Step-by-step explanation:

x1 y1  x2 y2

0 -4  5 1

(Y2-Y1) (1)-(-4)=   5  ΔY 5

(X2-X1) (5)-(0)=    5  ΔX 5

slope= 1          

B= -4          

Y =1X  -4    

Answer:

Let X equal the remaining time she needs to practice.

You would have 2x

The combined total needs to be 6 hours or greater.

You need to add the amount she already practiced to 2x.

Now you have: three and one fourth + 2x

This needs to be greater than or equal to 6.

Ans:- three and one fourth + 2x ≥ 6

Answer:

b

Answer:

x = 8

Step-by-step explanation:

Hi there!

[tex]\displaystyle\frac{9}{24}=\frac{3}{x}[/tex]

9/24 can be simplified by dividing both the numerator and denominator by 3:

[tex]\displaystyle\frac{9\div3}{24\div3}=\frac{3}{x}\\\\\\\frac{3}{8} =\frac{3}{x} \\\\\\x=8[/tex]

Therefore, x is 8.

yes

Step-by-step explanation:

try using a vertical line, if you move the vertical line across the graph and the line touches the graph only at one point, than it means it is a function

Answer:

This graph represents a function

Step-by-step explanation:

By its definition, a function is a relation or a correlation between two sets (groups) of values where every input corresponds to only one output. What this means is that every input in a function can only have one output. This characteristic results in a unique property in the graph of a function, that is, the verticle line test.  The verticle line test states that when one draws a line through the graph of a function, the line can only intersect the graph in exactly one place in the function. If the line intersects the graph in more than one place, then the graph does not represent a function. In the given situation, any verticle line drawn on the graph only intersects the graph in one place, thus the graph represents a function.

Answer:

c

Step-by-step explanation:

first term=1

common d=4

nth term=a+(n-1)d

7881=1+(n-1)4

7881=1+4n-4

7884=4n

n=1971

Starting with n = 0, the n-th term in the sequence is

4n + 1

so any number in the sequence must have a remainder of 1 when divided by 4.

We have

4551 = 1137×4 + 3

10091 = 2522×4 + 3

7881 = 1970×4 + 1

13351 = 3382×4 + 3

Hey there! I'm happy to help!

To find the hypotenuse of a right triangle given two legs, you use the Pythagorean Theorem.

a²+b²=c², where a and b are the legs and c is the hypotenuse.

Let's plug our values into the equation and solve for c (our hypotenuse).

75²+100²=c²

Square the numbers

5625+10000=c²

Add them

c²=25625

Square root both sides

c=125

Have a wonderful day and keep on learning! :D

Answer:

since the distance from the outside edges is 26 1/2 feet, divide that by 2 to get the distance from the center to the edge ( 26 1/2 / 2 = 13 1/4 feet)

the stage is 76 feet so divide that by 2 to find the center 76/2 = 38 feet

now subtract the 13 1/4 from 38

38 - 13 1/4 = 24 3/4 feet from the side of the stage to the edge of the trap door

a little easier way would be to subtract the 26 1/2 from 76 and then divide by 2

76-26 1/2 = 49 1/2 / 2 = 24 3/4

A. exponential; y = 89 • 0.62x

Step-by-step explanation:

exponential; y = 89 • 0.62^x

Answer:

Option B exponential y = 89 · 0.62x

Step-by-step explanation:

The table shows the estimated number of deer living in a forest over a five year period.

Year            Number of deers

0                     89

1                      55

2                     34

3                     21

4                     13

Now we have to find the model representing this situation. Difference in number of deer, in the forest.

We can see there is a common ratio between each successive term r =  = 0.618

r =  = 0.618

so it can be represented by an exponential model.

Answer:

134.61 is the answer . hope This helps

Answer:

The answer is 134.61

Step-by-step explanation:

We have, 26% × x = 35

Or, 26/100 × x = 35

We have: x = 35 × 100/26

35×100 = 3,500

3,500 ÷ 26 = 134.61

x = 134.61

If you use a calculator, simply put 35×100÷26, which will give you the answer.

Answer:

a. 65 degree

B. 25 degree

c. 25 degree

d. 75 degree

Step-by-step explanation:

shown in photo.

Mark me brain list if it help you

Answer:

a = 65°

b = 25°

c = 25°

d = 75°

Step-by-step explanation:

60 + a + 55 = 180 (Angles of a straight line)

a + 115 = 180

a = 180 - 115

a = 65°

a + b + 90 = 180 (Interior angles of a triangle add up to 180°)

65 + b + 90 = 180

b + 155 = 180

b = 180 - 155

b = 25°

b = c (Vertically opposite angles are equal)

c = 25°

d + 15 = 90 (Complementary angles)

d = 90 - 15

d = 75°
