I Need Help Pls, Trigonometry: Finding Sides And Angles

Answers

Answer 1

Answer:

13.  PS = 21.37

14.  68.74°

Step-by-step explanation:

13.   QS/39 = tan 28

      QS = 39 tan 28

sin 76 = QS/PS

PS sin 76 = QS

PS = QS/sin 76

    = 39 tan 28/sin 76

    = 21.37

14.    tan 47 = BD/18

        BD = 18 tan 47

        cos CDB = 7/BD

                        = 7/(18 tan 47)

         m∠CDB = arccos [7/(18 tan 47)

                        = arccos .362644...

                        =  68.74°

Answer 2

The trigonometry we get  PS = 21.37 and  m∠CDB=  68.74°

Trigonometry finding sides and angles

We have to find

What is the formula of tan?

The value of tan is opposite side/adjacent side

Therefore we get

13.   QS/39 = tan 28

QS = 39 tan 28

sin 76 = QS/PS

PS sin 76 = QS

PS = QS/sin 76

PS = 39 tan 28/sin 76

PS = 21.37

14.    tan 47 = BD/18

 BD = 18 tan 47

 cos CDB = 7/BD

cos CDB= 7/(18 tan 47)

m∠CDB = arccos [7/(18 tan 47)

m∠CDB = arccos .362644...

 m∠CDB =  68.74°

A right prism has a volume of 65 cubic inches. The prism is enlarged so its height is increased by a factor of 20, but the other dimensions do not change. What is the new volume? A.1000 in .3 B.1300 in .3 C.1200 in. 3 D. 1100 in.3

Answers

Answer:

Volume of a right prism = 65 cubic inches

Its height is increased by a factor of 20.

To find:

The new volume of the prism if the other dimensions do not change.

Solution:

The volume of a prism is:

[tex]Volume=Bh[/tex]

Where, B is the base area and h is the height.

A right prism has a volume of 65 cubic inches.

[tex]65=Bh[/tex]

The height of prism is increased by a factor of 20. So, the new volume is:

[tex]Volume=B(20h)[/tex]

[tex]Volume=20(Bh)[/tex]

[tex]Volume=20(65)[/tex]

[tex]Volume=1300[/tex]

The volume of the new prism is 1300 in³.

Therefore, the correct option is B.

If measured at the same moment, the length of a person's shadow varies directly with the height of the person. If a 3 foot child casts a 5 foot shadow, what is the length of the shadow of a 6 foot adult?​

Answers

Answer:

10 ft

Step-by-step explanation:

let l be length of shadow and h the height of a person

Given l varies directly with h then the equation relating them is

l = kh ← k is the constant of variation

To find k use the condition h = 3, l = 5 , then

5 = 3k ( divide both sides by 3 )

[tex]\frac{5}{3}[/tex] = k

l = [tex]\frac{5}{3}[/tex] h ← equation of variation

When h = 6 , then

l = [tex]\frac{5}{3}[/tex] × 6 = 5 × 2 = 10 ft

The discriminant if a quadratic equation is negative. One solution is 4 + 7i. What is the other solution? *
7 - 4i
4 - 7i
- 4 + 7i
7 + 4i

Answers

Answer:  B) 4 - 7i

==========================================================

Explanation:

When you have a quadratic in the form ax^2 + bx + c = 0, where a,b,c are real numbers, then a negative discriminant leads to having a pair of complex roots. The roots come in conjugate pairs meaning that p+qi is one root while p-qi is the other root. The p,q are real numbers.

In the case of 4+7i being one root, we have p = 4 and q = 7, since it matches with p+qi. The other root must be 4-7i since it matches with p-qi.

In short, we flip the plus to a minus when going from 4+7i to 4-7i. All of this applies when we have a,b,c as real numbers.

If we allowed a,b,c to be complex numbers, then the roots may not necessarily come in conjugate pairs.

Question 7: The ratio of M's to A's cat is 5:7. Meg's cat weighs 20 kg. How
much more does Anne's cat weigh?
A) 28 kg
B) 2 kg
C) 8 kg
D) 9.3 kg

Answers

Answer: C

Step-by-step explanation: The ratio shows that Anne's cat is 2kg heavier, but Meg's cat weighs 20kg which is 4 times what the ratio shows the weight is, so the difference of the weight is also 4 times greater, which is 8kg!

The value of weight of Anne's cat will be 28 kg. Then the correct option is A.

What is the ratio?

The utilization of two or more additional numbers that compares is known as the ratio.

The definition of simplicity is making something simpler to achieve or grasp while also making it a little less difficult.

The ratio of M's to A's cat is 5:7. Meg's cat weighs 20 kg.

Let 'x' be the weight of Anne's cat. Then the equation is given as,

5 / 7 = 20 / x

Simplify the equation, then we have

5 / 7 = 20 / x

1 / 7 = 4 / x

x = 28 kg

The value of weight of Anne's cat will be 28 kg. Then the correct option is A.

Round the number 74.054 to the nearest tenth

Answers

Answer:

74.054 rounded to the nearest tenth is equivalent to 74.1

Step-by-step explanation:

Since you're rounding 74.054 to the nearest tenth, you need to focus on the hundredths place. If the number on the hundredths place is greater than or equal to 5, then you round up. If not, keep the number in the tenths place the same. In this case, 5 is in the hundredths place, which means you need to round the 0 in the tenths place up by 1. So 74.054 rounded to the nearest tenths is equivalent to 74.1.
