Find the solutions for a triangle with a = 16, c =12, and B = 63º.

a. A = 71.6°; C = 52.89; b =12.0

C. A = 68.6° C = 45.40; b=12.0

b. A = 71.6°; C = 45.40; b =15.0

d. A = 68.6°; C = 52.89; b=15.0

Answers

Answer 1

Answer:

b. A = 71.6°; C = 45.40°; b =15.0

Step-by-step explanation:

The missing values can be found with the help of the Law of Cosine and properties of triangles:

Side b (Law of Cosine)

[tex]b = \sqrt{a^{2}+c^{2}-2\cdot a \cdot c \cdot \cos B}[/tex]

[tex]b = \sqrt{16^{2}+12^{2}-2\cdot (16)\cdot (12) \cdot \cos 63^{\circ}}[/tex]

[tex]b \approx 15.022[/tex]

Angle A (Law of Cosine)

[tex]\cos A = -\frac{a^{2} - b^{2}-c^{2}}{2\cdot b \cdot c}[/tex]

[tex]\cos A = - \frac{16^{2}-15.022^{2}-12^{2}}{2\cdot (15.022)\cdot (12)}[/tex]

[tex]\cos A = 0.315[/tex]

[tex]A= \cos^{-1} 0.315[/tex]

[tex]A \approx 71.639^{\circ}[/tex]

Angle C (Sum of internal angles in triangles)

[tex]C = 180^{\circ} - 63^{\circ} - 71.639^{\circ}[/tex]

[tex]C = 45.361^{\circ}[/tex]

Hence, the right answer is B.

PLEASE HELP! The density of atmosphere (measured in kilograms/meter) on a certain planet is found to decrease as altitude increases (as measured from

the planet's surface). What type of relationship exists between the altitude and the atmospheric density, and what would the atmospheric

density be at an altitude of 1.291 kilometers?

Answers

Answer:

The relationship that exist between the altitude and the atmospheric density is an inverse relationship.

[tex]D = \frac{k}{1291} kg/m^3[/tex]

Step-by-step explanation:

since the density of the atmosphere decreases as the altitude increases, the relationship that exist between the altitude and the atmospheric density is an inverse relationship. This can be represented by:

[tex]D = \frac{k}{H}[/tex], where k is the constant, H is the altitude in meters and D is the atmospheric density in kg/m.³

When the altitude is 1.291 km, i.e H = 1.291 km = 1291 m,the atmospheric density D is:

[tex]D = \frac{k}{1291} kg/m^3[/tex]

deductions for the first quarter?

O A. $1229.00

O B. $806.00

O

C. $1302.00

O

D. $1209.00

Answers

Answer:

D) $1,209.00

The maximum FUTA deductions for the first quarter = $1,209.00

Step-by-step explanation:

The Federal Unemployment Tax Act (FUTA) is a tax which employers who pay their employees must pay in order to fund the state unemployment agencies. This tax is only payable on the first $1,500 to $7,000 on each emoloyees wage in a single quarter.

The FUTA current rate is 6.2%

Given that,

Employee 1 earned $5,500 in quarter 1.

Employee 2 earned $7,500 in quarter 1.

Employee 3 earned $8,000 in quarter 1.

Employee 2 and employee 3 would only be charged for their first $7,000 since they earned more than $7,000.

Therefore, the maximum FUTA deductions for the first quarter would be calculated as:

(0.062 * 5,500)+(0.062 * 7,000) + (0.062 * 7,000)

= $341 + $434 + $434

= $1,209

The maximum FUTA deductions for the first quarter = $1,209.00

How are the solution sets to s<3 and |s|<3 different ?

Answers

Answer:

The solution set for [tex]s<3[/tex] would be (-∞,3)

The solution set for [tex]|s|<3[/tex] would be (-3,3)

Step-by-step explanation:

The solution set for [tex]s<3[/tex] can be any number that is lower than 3.

When we have the inequality  [tex]|s|<3[/tex], we need to rewrite this without the absolute values to find our answer

[tex]|s|<3[/tex]

[tex]s<[/tex] ± [tex]3[/tex]

This can be be split into [tex]s<3, s<-3[/tex]

But, there one thing that needs to be done to the inequality with the-3. As we multiplied it by a -1 to make it negative, we must reverse the sign of the inequality. This leaves us with [tex]s<3, s>-3[/tex]

Now, we can combine these to get one inequality

Complete the equation that represents this situation.

Answers

Answer:

12 pounds

Step-by-step explanation:

It takes 12 pounds for the UPS and FedEx packages to cost the same amount to ship.

What is equation?

An equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.

Given that, UPS charges $6.00 for the first pound, $1.00 for the second pound, and $0.15 for each additional pound. FedEx charges $4.00 for the first pound, $2.00 for the second pound, and $0.25 for each additional pound.

Equations to represent the situation in this problem.

x=weight of package

UPS cost=6+1+0.15(x-2)

UPS cost=6+1+0.15x-0.3

UPS cost=6.7+0.15x

FedEx cost=4+2+.25(x-2)

FedEx cost=4+2+0.25x-0.5

FedEx cost=5.5+0.25x

Next, we can set the two equations equal to each other to solve for x.

6.7+0.15x=5.5+0.25x

6.7+0.15x-5.5=5.5+0.25x-5.5

1.2+0.15x-0.15x=0.25x-0.15x

1.2/0.1=0.1x/0.1

x=12

Hence, It takes 12 pounds for the UPS and FedEx packages to cost the same amount to ship.

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

   = (6-4)/(3-0)

   = 2/3

The equation of a line in slope intercept form is

y = mx+b where m is the slope and b is the y intercept

y = 2/3x +4

Answer:

y = 2/3x +4

Step-by-step explanation:

let the 2 unknown be a and b

X = 0, Y = 4 -> 4 = 0*a+b -> b = 4

Y =0, X = -6  -> 0 = -6*a + 4 -> a = -4/-6 = 2/3

a equals 9 comma


b equals 8 comma


A equals 50 degrees

Answers

Answer:

B = 42.9°

C = 87.1°

c = 7.4

Step-by-step explanation:

In this problem we are given two sides and one angle of a triangle ABC. The given values are:

a = 9

b = 8

A = 50°

In this case, there wil be only one solution, because the side opposite the given angle (side a) is longer than side b that was also given.

Calculating, let's the the law of sines.

[tex] \frac{sin A}{a} = \frac{sin B}{b} = \frac{sin C}{c} [/tex]

[tex] \frac{sin 50}{9} = \frac{sin B}{8} = \frac{sin C}{c} [/tex]

Taking for A & B, we have:

[tex] \frac{sin 50}{9} = \frac{sin B}{8} [/tex]

Let's cross multiply

(sin 50°)(8) = 9 sinB

Solving further,

[tex]sin B = \frac{8 sin 50}{9}[/tex]

[tex] sin B = \frac{6.128}{9}[/tex]

[tex] B =sin^-^1(0.68)[/tex]

B = 42.9°

Since the total angle of a triangle is 180°, to find C, we have:

C = 180 - 50 - 42.9

C = 87.1°

To find the length of c, let's also use the sine formula.

[tex]\frac{sin B}{b} = \frac{sin C}{c} [/tex]

[tex]\frac{sin 42.9}{8} = \frac{87.1}{c} [/tex]

Cross multiplying

8c = 87.1 sin 42.9

[tex] c = \frac{87.1 sin42.9}{8} [/tex]

c = 7.4

Jake received a student loan for $12,000. He plans on paying off the loan in five years. At the end of five years, J. Cole have paid $3600 in interest. What is a simple interest rate on the student loan?

Answers

Answer:

The simple interest rate on the student loan is 6%.

Step-by-step explanation:

To solve for the simple interest rate, use the formula for total simple interest:

[tex]I = Prt[/tex]

[tex]I[/tex] = total interest paid

P = principal, or starting value

r = interest rate in decimal form

t = time in years

State known values

P = 12,000

t = 5

[tex]I[/tex] = 3,600

Substitute known values and isolate "r"

[tex]I = Prt[/tex]

3,600 = (12,000) (r) (5)

3,600 = (60,000) r

r = 0.06

Since "r" is given as a decimal, convert this to a percentage by multiplying by 100.

0.06 = 6%

∴ The simple interest rate on the student loan is 6%.

Answer=6%

Step-by-step explanation:

Principal(P)=12000

Time(T)=5  yrs

Interest(I)=3600

We have,

I=PTR/100

3600=(12000*5*R)/100

3600*100=60000*R

R=360000/60000

R=6%
