The terminal side of Ø is in quadrant II and sin ø = 5/13 What is cos ø?

A. 5/12
B. -12/13
C. -5/12
D. 12/13

Answers

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.

Quadrants and the "cast" Rule:In the first quadrant, the values for sin, cos, and tan are positive.In the second quadrant, the values for sin are positive only.In the third quadrant, the values for tan are positive only.In the fourth quadrant, the values for cos are positive only.

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.

Step-by-step explanation:

PLSS HELPPPP MEE ITS DUE TMRW

Answers

Answer:

the turning point is (-2,-1)

i dont know the turning point but i hope this helps

Step-by-step explanation:

Answer:

a) (-2 , -1)

b) (-1 , 0) and (-3 , 0)

Step-by-step explanation:

For part a)

We can find the coordinates of the turning point by seeing at the graph where it turns the other way or in simpler words the axis of symmetry so if see the graph the axis of symmetry is the line x = -2 so that means the turning point is (-2 , -1).

For finding the turning point mathematically we compare the equation to its standard form which is:

[tex]x^2+4x+3=a(x-h)^2+k[/tex]

where h is the x coordinate  and k is the y coordinate of the turning point of the equation (h , k) = (x , y).

so just solve the left side,

[tex]a(x-h)^2+k\\a((x)^2-2(x)(h)+(h)^2)+k\\a(x^2-2xh+h^2)+k\\\\ax^2-2ahx+ah^2+k=x^2+4x+3\\[/tex]

and so we compare the coefficients of x^2 on the right and left side we get

[tex]a=1[/tex]

if we compare the coefficients of x on the right and left side we get

[tex]-2ah=4\\-2(1)h=4\\-2h=4\\h=\frac{4}{-2}\\\\h=-2[/tex]

now we compare the constants on the right and left side we get

[tex]ah^2+k=3\\(1)(-2)^2+k=3\\(1)(4)+k=3\\4+k=3\\k=3-4\\k=-1[/tex]

so the turning point is (-2 , -1) proven mathematically and graphically as well

For part b)

Roots of the equation are also called as x-intercepts which means where the graph intersects/cuts the x-axis so if see the graph it cuts the x-axis at 2 points  firstly at -3 and then at -1 so the roots of the equation would be (-1 , 0) and

(-3 , 0) the y coordinate is zero when the points lies on the x-axis.

for mathematically solving the equation we would equate the equation to zero

[tex]y=x^2+4x+3\\x^2+4x+3=0[/tex]

Now solve it by either factorizing or by using the quadratic formula we would get two values for x those are the roots of the equation

we solve it by factoring

[tex]x^2+4x+3=0\\x^2+3x+x+3=0\\x(x+3)+1(x+3)=0\\(x+3)(x+1)=0\\x=-3\ ,\ x=-1\\[/tex]

proven mathematically as well as graphically.

A stereo speaker in the shape of a triangular pyramid has a height of 6 inches. The area of
the base of the speaker is 11 square inches.
What is the volume of the speaker in cubic inches?

Answers

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].

Four times the greatest of three consecutive odd

What is the greatest of the three consecutive
odd integers?

Answers

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].

What are integers ?

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].

Ravi got 80 candies for her daughter's birthday. Each candy weighed 50 grams. If was price of candies was Rs. 10 per kilogram, how much did he pay?

Answers

Answer:

Rs. 40

Step-by-step explanation:

50g = 1 candy1000g = 20 candies20 candies = Rs. 1080 candies = Rs. 40

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

What are Arithmetic operations?

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.

One triangle shown is formed by the tree, its shadow, and a line of sight from the ground to the top of the tree. The other is formed by Manny, his shadow, and a line of sight from the ground to the top of his head.Manny is 512 feet tall, and his shadow is 414 feet long. The shadow of the tree is 17 feet long. How can you determine the height of the tree?

Answers

Answer:

21 feet

Step-by-step explanation:

To solve this question, we would be using the proportion

Shadow /Height

From the question:.

Manny's shadow = 414 feet

Manny's Height = 512 feet

Height of the tree = ? = x

Shadow of the tree = 17 feet

Hence:

414/512 = 17/ x

Cross Multiply

414 × x = 512 × 17

x = 512 × 17/414

x = 21.024154589 feet

x ≈ Approximately = 21 feet

The height of the tree = 21 feet

The height of the tree is 21 feet.

Given that,

Manny is 512 feet tall, and his shadow is 414 feet long. The shadow of the tree is 17 feet long. Here we assume the height be x

Based on the above information, the calculation is as follows:

[tex]414\div 512 = 17\div x\\\\414 \times x = 512 \times 17\\\\x = 512 \times 17\div 414[/tex]

x = 21.02

= 21 feet

Therefore we can conclude that the height of the tree is 21 feet.

Answers

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

The ratio of cherry candies to grape candies in a bag is 3:5. After your friend eats half of the grape flavored candies and only one cherry flavored candy, the ratio of cherry to grape candies is 7:6. How many candies are left in the bag?

Answers

Answer:

65

Step-by-step explanation:

The computation of the number of candies left in the bag is as follows:

Let us assume the cherry candies be c ;

And, grape candies be g

Now the ratio between them is 3:5

And, in the case when half of the candies are eaten and one cherry is also eaten so the ratio is

 (c - 1) ÷ (g ÷ 2) = 7 ÷ 6

After subsitution

It would be

(3 ÷ 5g - 1) ÷ (g ÷ 2) = 7 ÷ 6

Now after solving it,

g = 60

And, the c = 35

As the candies are half so it would be 30 now

So, the number of candies together is

= 35 + 30

= 65
