HELP MEEEEEEEE PLEASE

Step-by-step explanation:

=(1+ sin^2 A/cos^2 A).cos^2 A

=[(cos^2 a+sin^2 a)/cos^2 a].cos^2 A

=[1/cos^2 a] . cos^2 a

=1

Answer:

x<5

Step-by-step explanation:

mark me brainliest

All book are LESS THAN 5 dollars. Therefore all prices (x) have to be less that 5 hence x<5

Answer:

The most expensive a book could be is $4.99

The inequality to represent the costs of books at the sale is c < 5

Aim :

We have to convert them into improper fractions as they are into mixed fractions. So let's start..!!

Solution :

1) [tex] \bf{ 1\dfrac{5}{8} }[/tex]

Multiply 8 into 1 and add 5 into it,

[tex]: \: \implies \: \sf{ \dfrac{8 \times 1 \: + \: 5}{8}} \\ \\ : \: \implies \: \sf{ \dfrac{8 \: + \: 5}{8}} \\ \\ : \: \implies \: \red{\sf{ \dfrac{13}{8}}}[/tex]

_______________________________________

2) [tex] \bf{ 4\dfrac{2}{5} }[/tex]

Multiply 4 into 5 and add 2 into it.

[tex]: \: \implies \: \sf{ \dfrac{4\times 5 \: + \: 2}{5}} \\ \\ : \: \implies \: \sf{ \dfrac{20 \: + \: 2}{5}} \\ \\ : \: \implies \: \red{\sf{ \dfrac{22}{5}}}[/tex]

_______________________________________

3) [tex] \bf{ 2\dfrac{6}{8} }[/tex]

Multiply 8 into 2 and add 6 into it after multiplying.

[tex]: \: \implies \: \sf{ \dfrac{2 \times 8 \: + \: 6}{8}} \\ \\ : \: \implies \: \sf{ \dfrac{16 \: + \: 6}{8}} \\ \\ : \: \implies \: \red{\sf{ \dfrac{22}{8}}}[/tex]

Answer:

x = 156

Step-by-step explanation:

Yes.  The comment was correct.

The central angle and the Arc measurement are the same amount (in degrees)

So The entire circle is 360 degrees.

Answer = 360 - the two central angles.

Answer = 360 - 65 - 139

Answer = 360 - 204

Answer = 156

Answer:

cos

Step-by-step explanation:

its adjacent over hypotenuse

Answer: cos

Step-by-step explanation:

You don't have a value for the side opposite the angle, you only have your hypotenuse and your adjacent side. Hope this helps.

Answer:

plays an instrument/plays sports = 0.46

plays an instrument/does not play sports = 0.54

does not play an instrument/plays sports = 0.73

does not play an instrument/does not play sports = 0.27

Step-by-step explanation:

plays an instrument/plays sports = 6 divided by 13

plays an instrument/does not play sports = 7 divided by 13

~ you divide by 13 since the row's numbers add up to 13

does not play an instrument/plays sports = 8 divided by 11

does not play an instrument/does not play sports = 3 divided by 11

~ you divide by 11 since the row's numbers add up to 11

A., 10 inches.

Answer:

  a° = 52°

  b° = 64°

  c° = 128°

Step-by-step explanation:

a) The 52° angle and the angle marked a° both intercept the same arc, so have the same measure.

  a° = 52°

__

b) The base angles of the isosceles triangle are equal. This means they are ...

  b° = (180° -52°)/2 = 128°/2

  b° = 64°

__

c) The arc intercepted by angle b° is twice the measure of angle b°, so is ...

  c° = 2(64°)

  c° = 128°

Answer:

yes

Answer:

1000 hours

Step-by-step explanation:

∫xf(x)dx = ∫x*xdx (1,0) + ∫x*(8-x)dx (2,1)

∫xf(x)dx = ∫x²dx (1,0) + ∫8x - x²dx (2,1)

∫xf(x)dx = ∫x²dx (1,0) + ∫8xdx (2,1) - ∫x²dx (2,1)

∫xf(x)dx = x³/3(1,0) + 8x²/2 (2,1) - x³/3(2,1)

∫xf(x)dx = 1/3 + 8(4/2 - 1/2) - (8/3 - 1/3)

∫xf(x)dx = 1/3 + 8(2-0.5) - (7/3)

∫xf(x)dx = 1/3 + 8(1.5) - 7/3

∫xf(x)dx = 1/3 + 12 - 7/3

∫xf(x)dx = - 6/3 + 12

∫xf(x)dx = - 2 + 12

∫xf(x)dx = 10

Answer:

28 classes

Step-by-step explanation:

84/3 = 28 classes

Answer:

28 classes didn't learn about the Holocaust

Step-by-step explanation:

If there are 84 classes and two-thirds learned about the Holocaust that means that you have to divide by three.

84 ÷ 3 = 28

Then, you can check your answer by multiplying 28 × 3 = 84

Answer:

You can use formulas for finding them but this is my best method.

Step-by-step explanation:

21=3×7

35=5×7

49=7×7

Finding the hcf or gcf you will first find the common numbers between all the prime factors which is 7.

Therefore gcf of 21,35 and 49 is 7

Answer:

x axis

Step-by-step explanation:

Answer:

y=-5x+4

Step-by-step explanation:

m=(y2-y1)/(x2-x1)

m=(-1-(-6))/(1-2)

m=(-1+6)/-1

m=5/-1

m=-5

y-y1=m(x-x1)

y-(-6)=-5(x-2)

y+6=-5(x-2)

y=-5x+10-6

y=-5x+4

Answer:

(x + 2)² + 1

Step-by-step explanation:

Given

x² + 4x + 5

To express in vertex form use the method of completing the square

add/ subtract ( half the coefficient of the x- term)² to x² + 4x

= x² + 2(2)x + 4 - 4 + 5

= (x + 2)² + 1 ← in vertex form
