Answer:

D. 3(x+2) can be rewritten as 3x + 6 using the distributive property

Step-by-step explanation:

Given

[tex]3(x + 2) = 3x + 6[/tex]

Required

Explain

From the list of given options, option D answers the question.

This is because, the expression above involves distributive property and only option D correctly states that.

A distributive property is:

[tex]a*(b + c) = a*b + a * c[/tex]

In this case:

[tex]a = 3[/tex]  [tex]b = x[/tex]   and [tex]c = 2[/tex]

So:

[tex]a*(b + c) = a*b + a * c[/tex]

Substitute values for a, b and c

[tex]3*(x + 2) = 3 * x + 3 * 2[/tex]

[tex]3(x + 2) = 3x + 6[/tex]

Answer:

C. Both expressions involve addition.

Answer:

Step-by-step explanation:

The set up will give a right angled triangle

Given

Distance of point A from the flagpole = 25feet

If angle of elevation is 30°

Required

Height of flagpole (opposite)

Using TOA

tan theta = opp/adj

tan30° = opp/25

opp = 25tan30°

opp = 14.4feet

Hence the height of flagpole when the angle of elevation is 30° is 14.4feet

If angle of elevation is 38°

Required

Height of flagpole (opposite)

Using TOA

tan theta = opp/adj

tan38° = opp/25

opp = 25tan38°

opp = 19.53feet

Hence the height of flagpole when the angle of elevation is 38° is 19.5feet

If angle of elevation is 45°

Required

Height of flagpole (opposite)

Using TOA

tan theta = opp/adj

tan45° = opp/25

opp = 25tan45°

opp = 25feet

Hence the height of flagpole when the angle of elevation is 45° is 25feet

Answer:

y-intercept: [tex]y=0[/tex]

axis of symmetry: [tex]x=0[/tex]

vertex: [tex](0,0)[/tex]

Step-by-step explanation:

To find the y-intercept, set x = 0 and solve for y.

I am assuming f(x) = y

[tex]y=4x^2[/tex]

[tex]y=4(0)^2[/tex]

[tex]y=0[/tex]

The y-intercept of the equation is y = 0.

Now, for the axis of symmetry, you need the equation [tex]x=\frac{-b}{2a}[/tex]

In an equation.. [tex]y=ax^2+bx+c[/tex]

In this case, there is only an a, so plug in the values into the equation.

[tex]x=\frac{0}{2(4)}[/tex]

[tex]x=0[/tex]

The axis of symmetry is x = 0.

To find the vertex, change the format of the equation from standard form to vertex form.

Vertex form: [tex]y=a(x-h)^2+k[/tex]

The vertex is [tex](h,k)[/tex]

[tex]y=4x^2 = 4(x+0)^2+0[/tex]

[tex](h,k)=(0,0)[/tex]

The vertex in this case is (0,0).

Answer:

S(50) = 0

Step-by-step explanation:

The initial condition is S(0) = 0, so start at the origin.  The slope there is approximately 1.  So as t increases by a small amount, S increases by the same amount.  Continuing this logic, we end up tracing the vector field until we get to t=50, where S is approximately 0.

Each little tickmark is a slope value telling you which direction to go. If you place yourself at the origin (0,0) then the tick mark here tells us to go roughly in the northeast direction. As you step forward to the northeast just a tiny bit, the slope value changes to aim more toward the east (rather than north). For more information, check out Euler's method. Specifically it's Euler's method dealing with slope fields.

The diagram below shows what could be each step of this process. Each red dot is a stepping stone, so to speak, going from (0,0) to (50,0). This is an approximation. Without the actual function F(t, S), it's hard to say where exactly S(50) is located. But S(50) = 0 is a fairly good guess I think. MathPhys has a great diagram showing what could be the solution for S(t) given the initial condition S(0) = 0. Note how they drew a curve through all of the red points I've marked.

Answer:

$5487.38

Step-by-step explanation:

Given that:

Interest currently made = $2112.64

Time = 7 years

Rate of interest = 5.5% annual

To find:

The price for which the bond was originally bought ?

Solution:

We need to find nothing but the principal amount.

First of all, let us have a look at the formula for Simple Interest.

[tex]Simple\ Interest = \dfrac{PRT}{100}[/tex]

Where [tex]P[/tex] is the principal amount

[tex]R[/tex] is the Rate of Interest

[tex]T[/tex] is the time for which the investment is made

Let us put the given values in the formula:

[tex]2112.64 = \dfrac{P\times 5.5\times 7}{100}\\\Rightarrow P =\dfrac{2112.64\times 100}{5.5\times 7}\\\Rightarrow P =\dfrac{211264}{38.5} \\\Rightarrow \bold{P =\$5487.38}[/tex]

Answer:

The answer is 91/12 in exact form or 7 7/12 in mixed number form.

Step-by-step explanation:

Reduce the expression, if possible, by cancelling the common factors.

-2(y-1) = 9

Use distributive property:

-2y + 2 = 9

Subtract 2 from both sides

-2y = 7

Divide both sides by-2:

Y = -7/2

Have a good day :)

The weight of the baby at birth is 8 pounds.

Given,

The weight, in pounds, of a newborn baby tt months after birth, can be modeled by W.

The table below has select values showing the linear relationship between

t and W.

We need to determine the weight of the baby at birth.

The table is given as:

1         10

4.5     17

9        26

The table has two columns and it always has a relationship between them depending on the question.

Example:

Miles.        Hours

2.               3

6.               9

8.               12

Here we see that every 1-5 hours there's a mile increase.

We have,

W = weight of the baby

t = number of months.

From the table:

The baby weight-

At 1 month = 10

At 4.5 months = 17

At 9 months = 26

We see that,

In,

(4.5 - 1) = 3.5 months there is an increase of (17 - 10) = 7 pounds.

So we can write it as:

3.5 months = 7 pounds

1 month = 7/3.5

1 month = 70/35 = 10/5 = 2 pounds

This means in after every month there is an increase of 2 pounds.

We have,

1In the first month, the weight of the baby is 10 pounds.

And every month there is an increase of 2 pounds.

So,

The weight of the baby at birth is:

= 10 - 2

= 8 pounds

Thus the weight of the baby at birth is 8 pounds.

Answer:

The car dealer must sell 105 cars in May to reach his goal.

Step-by-step explanation:

Given that the car dealer sold 84 cars in April, and wants to increase his May sales by 25%, to determine the number of cars he must sell to reach his goal it is necessary to perform the following calculation:

84 + (84 x 0.25) = X

84 + 21 = X

105 = X

Therefore, the car dealer must sell 105 cars in May to reach his goal.

Slope = 2

x-intercept = 8/2 = 4

y-intercept = 8/-1 = -8.00000

answer : 8.00000

Answer: y=2x-8

Slope 2 initial value I’m guessing is the y intercept which is -8

Answer:

first answer is 9.84

Step-by-step explanation:

9.84 is the square root of 97, rounded to the nearest hundredth.

the legs measure 9 x 9 and 4 x 4 = 81 and 16.

81 + 16 = 97, so your answer is the square root of 27, which rounded to the nearest hundredth, equals 9.84. Rounding towards the nearest whole, 10 would be your best bet.
