Answers

Answer 1

Answer:

213.7°

Step-by-step explanation:

The bearing of B from D is angle ADB,  Thus, ∠ADB = arctan(30/45) ≈ 33.7°

The bearing of D from B is that angle plus 180°, Thus, 180° +33.7° = 213.7°

The system of equations that can be used to model the situation is:

B. [tex]x + y = 27[/tex][tex]y = 3 + \frac{1}{2}x[/tex]

What is a system of equations?

A system of equations is when two or more variables are related, and equations are built to find the values of each variable.

In this problem, the variables are:

Variable x: number of boxes Juan packed.Variable y: number of boxes David packed.

Together they packed 27 boxes, hence:

[tex]x + y = 27[/tex]

David packed 3 more than half the number Juan packed, hence:

[tex]y = 3 + \frac{1}{2}x[/tex]

Hence, the system of equations that models the situation is:

B. [tex]x + y = 27[/tex][tex]y = 3 + \frac{1}{2}x[/tex]

In 16 years, Ben will be 3 times as old as he is right now.

Answer: 40

Step-by-step explanation:

The angles in a triangle are equal to 180

We can use this equation to find x

180 = 20 + 3x + x

Then we solve

160 = 4x

x = 40

Answer:

180 = 20 + 3x + x

X = 40

Step-by-step explanation:

180 = 20 + 3x + x

Combine like terms

180 = 20 + 4x

Subtract 20 on both sides

160 = 4x

Divide both sides by 4

40 = x

The lines represented by the equations 4y + 4x = 8 and y - x = -2 are
neither parallel nor perpendicular
the same line
perpendicular
parallel

Answers

Answer:

4 y = -4 x + 8    or y = -x + 2

y - x = -2           or y = x - 2

using the standard form for a line   y = m x + b

We see that in one equation m = -1 and in the other m' = +1

this is the condition for perpendicular lines

Drake bought a $110,000 life insurance policy at $12.95 for a 20 year term.
What will he pay over 20 years for the premium?

Answers

Drake will pay $28,490 over 20 years for the premium.

Data and Calculations:

Life insurance policy = $110,000

Insurance term = 20 years

Premium rate = $12.95 per $1,000

Total premium per year = $1,424.50 ($12.95 x $110,000/$1,000)

Total premium for 20 years = $28,490 ($12.95 x $110,000/$1,000 x 20)

Thus, Drake will pay a total premium of $28,490 for 20 years.

Answers

Regression equations are used to represent the relationship between the x and y variables.

The regression equation is [tex]\mathbf{y =-0.39X +467.84}[/tex]

Using a graphing calculator, we have the following parameters

Sum of x: [tex]\mathbf{\sum x = 269}[/tex]Sum of y: [tex]\mathbf{\sum y = 3170}[/tex]Mean of x: [tex]\mathbf{\bar x = 38.4286}[/tex]Mean of y: [tex]\mathbf{\bar y = 452.8571}[/tex]Sum of squares: [tex]\mathbf{SS_x = 1679.7143}[/tex]Sum of products: [tex]\mathbf{SP = -648.5714}[/tex]

The regression equation is represented as:

[tex]\mathbf{y =bX +a}[/tex]

Where:

[tex]\mathbf{b = \frac{SP}{SS_x}}[/tex] and [tex]\mathbf{a = \bar y-b \times \bar x}[/tex]

So, we have:

[tex]\mathbf{b = \frac{-648.5714}{1679.7143}}[/tex]

[tex]\mathbf{b = -0.39}[/tex]

Also, we have:

[tex]\mathbf{a = \bar y-b \times \bar x}[/tex]

This gives:

[tex]\mathbf{a = 452.8571 - (-0.39 \times 38.4286) }[/tex]

[tex]\mathbf{a = 467.84}[/tex]

Substitute values for (b) and (a) in [tex]\mathbf{y =bX +a}[/tex]

[tex]\mathbf{y =-0.39X +467.84}[/tex]

Hence, the regression equation is [tex]\mathbf{y =-0.39X +467.84}[/tex]

Anything number raised to the zero power is

Answers

Answer:

It is equal to 1 when raised to the zero power.

Step-by-step explanation:

Answer:

1

Step-by-step explanation:

Any number raised to the zero power equals 1. This is by definition to make the rules of exponents work.

Look at this example:

Any number (except zero) divided by itself equals 1.

For example, 25/25 = 1,

but 25 = 5²,

so 25/25 = 5²/5²

The rule of dividing two powers with the same base is to use the same base and subtract the powers.

5²/5² = 5^(2 - 2) = 5^0

By the rule of exponents, 5²/5² = 5^0,

but we saw above that 5²/5² = 25/25 = 1, so

5^0 must equal 1.

This led to the following definition of zero exponent.

Definition:

For any number a, a^0 = 1.
