Step-by-step explanation:

In Quadrant II, cosine is negative.

We know that sin²x + cos²x = 1, so:

cosx = sqrt[1 - sin²x]

= sqrt[1 - (5/13)²]

= sqrt(144/169)

= -12/13 (since cosx is negative here)

The answer is -12/13. (B)

Option B is correct.

According to the given question

We have,  sin ∅ = 5/13

From the trigonometric identities we know that

[tex]sin^{2}[/tex]∅ + [tex]cos^{2}[/tex]∅ =1

substitute the value of sin∅ in the above identity

[tex](\frac{5}{13} )^{2} + cos^{2}[/tex]∅  =1

⇒ [tex]\frac{25}{69} +cos^{2}[/tex]∅  =1

⇒ [tex]cos^{2}[/tex]∅ = 1 - [tex]\frac{25}{169}[/tex]

⇒ [tex]cos^{2}[/tex]∅ = [tex]\frac{169-25}{69} =\frac{144}{169}[/tex]

⇒[tex]cos[/tex]∅ = [tex]\sqrt{\frac{144}{169} }[/tex]

⇒cos∅ = ±[tex]\frac{12}{13}[/tex]

Since, ∅ is in quadrant II, then cos<0

⇒ cos∅ = -[tex]\frac{12}{13}[/tex]

Hence, option B is correct.

Answer:

[tex]V=22\ \text{inches}^3[/tex]

Step-by-step explanation:

Given that,

Height of a triangular pyramid = 6 inches

The area of the base of the speaker is 11 square inches

We need to find the volume of the speaker.

The formula for the volume of triangular pyramid is given by :

[tex]V=\dfrac{1}{3}Ah[/tex]

A is area of base and h is height

[tex]V=\dfrac{1}{3}\times 11\times 6\\\\=22\ \text{inches}^3[/tex]

So, the volume of the speaker is [tex]22\ \text{inches}^3[/tex].

Answer:

1.88 to 2 decimal places

Step-by-step explanation:

First, I plugged in 1.8 and 1.9:

1.8^3-3*1.8=0.432

1.9^3-3*1.9=1.159

Then, I plugged in 1.85:

1.85^3-3*1.85=0.78

Next, I plugged in 1.87 to get the answer closer to 1:

1.87^3-3*1.87=0.93

Finally, I plugged in 1.88 to get even closer to 1:

1.88^3-3*1.88=1.00

Hope this helps!

Answer:

Step-by-step explanation:

1.8=-0.568 is too small

1.9=0.159 is too big

1.87=-0.70797 is too small

1.88=0.004672 is too big

Next, I plugged in 1.87 to get the answer closer to 1:

1.87^3-3*1.87=0.93

Finally, I plugged in 1.88 to get even closer to 1:

1.88^3-3*1.88=1.00

1.875=-0.033203125 is too small

so it should be 1.88 to 2 decimal places

step-by-step explanation:

The standard form of a polynomial in one variable is a sum of terms in decreasing order of degree.

For brevity, terms with negative coefficients are usually written as subtractions rather than adding the additive inverses. That is, we would write  

x

x

rather than

(

)

x

In order to express

in standard form, we need to multiply it out, combining terms of like degree. We can use the FOIL mnemonic to help:

So we could take the second of these and put

The standard form is: [tex]x^2+10x+25[/tex].

We expand the given expression.

[tex](x + 5)^2\\=x^2+2(x)(5)+5^2\\=x^2+10x+25[/tex]

So the standard form is: [tex]x^2+10x+25[/tex].

Answer:

solution is (-2, 2) so x-coordinate of solution is -2

Step-by-step explanation:

Answer:

-2

Step-by-step explanation:

First, we have to write down both equations.

y = x + 4

3y = -2x + 2

Now we already have an equation that we can plug into the other equation.

= 3(x + 4) = -2x + 2

= 3x + 12 = -2x + 2

= 5x + 12 = 2

= 5x = -10

x = -2

Now we know that x = -2, and the question asks for the x-coordinate, which is -2.

Answer:

Rs. 40

Step-by-step explanation:

Ravi paid the amount of Rs. 40 for the candies for her daughter's birthday.

Arithmetic operations can also be specified by subtracting, dividing, and multiplying built-in functions. The operator that performs the arithmetic operation is called the arithmetic operator.

If the candies weighed 50 grams each, the total weight of the candies is 80 x 50 = 4000 grams.

To convert the weight from grams to kilograms, we divide by 1000. So, the total weight in kilograms is 4000 / 1000 = 4 kilograms.

If the price of candies was Rs. 10 per kilogram, the total cost for 4 kilograms is 4 x 10 = Rs. 40.

Therefore, he paid Rs. 40 for the candies.

Answer:

The largest is 25.

Step-by-step explanation:

If the first integer is x, the second is x+1 and the third is x+2.

When you multiply the largest by 4: (x+2)*4

It is 31 more than 3 times the smallest: (x+2)*4 = (x)*3+31

When you simplify you get : 4x+8 = 3x+31

Which means: x = 23

But since you want the largest you get: 23+2 = 25

The greatest of the three consecutive odd integers will be  [tex]19[/tex].

Integers are whole numbers that can be positive, negative and zero.

We have,

Let first integer [tex]= x[/tex]

Second integer [tex]= x+2[/tex]

Third integer  [tex]= x+4[/tex]

Now,

According to the question,

[tex]4(x+4) = 3(x)+31[/tex]

Simplifying;

[tex]4x+16=3x+31[/tex]

Taking [tex]x[/tex] variable on one side and constant on the other;

[tex]4x-3x=31-16[/tex]

[tex]x=15[/tex]

So,

Now substitute the value of [tex]x[/tex]  in every integer's equation,

i.e.

First integer [tex]= 15[/tex]

Second integer [tex]= 17[/tex]

Third integer  [tex]= 19[/tex]

So, the greatest of the three consecutive odd integers is [tex]19[/tex].

Hence, we can say that the greatest of the three consecutive odd integers will be  [tex]19[/tex].

Answer:

-1

Step-by-step explanation:

Remember, slope is rise/run

Start from a point on the line and count up and over until you reach another point on the line.

For example, start from (0,-2), count up and left until you get to (-2,0). This gets you 2/2, which reduces to 1.

Since the line represents a negative slope, the slope is -1.

Answer:

The y-values from top to bottom are;

3, 5 , 7, 9, 11, 13, 15

Step-by-step explanation:

Here, we want to fill out the given table

Let us have an equation linking x and y

From the question, we can have this as;

y = 5 + 2x

When x = -1

y = 5 + 2(-1) = 3

when x = 0

y = 5 + 2(0) = 5

when x = 1

we simply add 2 to the previous

= 5 + 2 = 7

when x = 2

= 7 + 2 = 9

when x = 3

= 9 + 2 = 11

when x = 4

= 11 + 2 = 13

when x = 5

y = 13 + 2 = 15
