Answer:

D 63

Step-by-step explanation:

First convert 3 1/2 to a decimal. Then multiply 3.5 by 18.

Answer: (0,-6)

Step-by-step explanation:

To find the y-intercept, we can rewrite the equation into slope-intercept form.

3x+5y=-30            [subtract both sides by 3x]

5y=-3x-30             [divide both sides by 5]

y=-3/5x-6

Now that the equation is in slope-interceot form, we know that the y-intercept is -6, we know that the answer is (0,-6).

Answer:

The largest African elephant weighed 13.5 tons (27,000 pounds) The world record holder weighed this much and stood 13ft/4m tall at the shoulder. There are other species of elephants, namely the Asian and the Indian, but they are much smaller than the African. The African elephant is the king among the giants on land. No other land animal comes close to the size of these creatures. It would take 165 full-grown men to make up the same weight as the world's record African elephant. The noise of an elephant digesting its food (when its tummy's growling) can be heard up to 600ft/183m away. Elephants actually have control over their digestive processes because they are able to stop the sounds of digestion when they sense danger. Here are some other cool elephant factoids:

Answer:

2 Miles.

Step-by-step explanation:

[tex]2\frac{2}{3}=\frac{8}{3}\\\\\frac{8}{3}*\frac{3}{4}=\frac{2}{1}*\frac{1}{1}\\\\[/tex].

Your final answer is 2 miles.

The values of the function are,

f (- 3) = 16,000 meaning a qualifying applicant with - 3 siblings in their household would get $16,000 in financial aid. This interpretation does not make sense in the context of the problem.

f (3) = 34,000 meaning a qualifying applicant with 3 siblings in their household would get $34,000 in financial aid. This interpretation makes sense in the context of the problem.

The domain for this function is x ≥ 0, indicating that the number of siblings must be a non-negative whole number or zero.

Given that,

The function is,

[tex]f (x) = 25000 + 3000x[/tex]

Where x is the number of siblings.

Hence, the values of the function are found as,

[tex]f (x) = 25000 + 3000x[/tex]

Put x = - 3;

[tex]f (- 3) = 25000 + 3000 \times - 3[/tex]

[tex]f (- 3) = 25000 - 9000[/tex]

[tex]f (- 3) = 16,000[/tex]

Put x = 3;

[tex]f (x) = 25000 + 3000x[/tex]

[tex]f (3) = 25000 + 3000 \times 3[/tex]

[tex]f ( 3) = 25000 + 9000[/tex]

[tex]f (3) = 34,000[/tex]

Since the given function is,'

[tex]f (x) = 25000 + 3000x[/tex]

Regarding the domain of the function,

Since the number of siblings (x) must be a non-negative integer, it represents the count of individuals.

Therefore, the appropriate domain for this function would be x ≥ 0, meaning x can be any non-negative whole number or zero.

For the given question some parts of the question are shown in the attached image.

Answer:

6.2

Step-by-step explanation:

Use the formula for calculating compound interest PN=P0(1+rk)Nk where r is the unknown, PN=2275, P0=1900, k=1, and N=3. Substitute the values into the formula and simplify.

2275=1900(1+r1)3⋅1

Let's simplify within the parenthesis and the exponent.

2275=1900(1+r)3

Divide both sides by 1900.  

22751900=(1+r)3

To isolate the variable, take the cube root of each side.

22751900−−−−−√3=1+r

Subtract 1 from each side to get r by itself.  

22751900−−−−−√3−1=r

Simplify for an answer of r≈0.062 which is the interest rate 6.2%.

Answer:

-3/2

Step-by-step explanation:

If the slope of a line is a fraction, flip it and change the sign to find the slope of a perpendicular.

-3/2

Supplementary angles are angles that sum up to 180 degrees

Step 1:

If m<x and m<y are supplementary, hence;

m<x + m<y = 180 ....................1

Step 2:

If m<y is a supplement to m<z, hence:

m<y + m<z = 180 ...........................2

Equating 1 and 2

m<x + m<y  = m<y + m<z

Subtract m<y from both sides

m<x + m<y-m<y  = m<y + m<z - m<y

m<x = m<z

This proves the statement m<x = m<z

Answer:

T < -19

Step-by-step explanation:

Answer:

Step-by-step explanation:

Step 1 : Find the slope/gradient (this is known as "m")

The slope formula is :

[tex]m = \frac{y2 - y1}{x2-x1}[/tex]

*Note that we are given 2 points:

For the first point (-2,-1) , this means x1 = -2 and y1 = -1

For the second point (2,4), this means x2 = 2 and y2 = 4

If we substitute those values into the slope formula you end up with this:

[tex]m = \frac{y2-y2}{x2-x1} = \frac{4 - (-1)}{2 - (-2)} = \frac{4+1}{2+2} =\frac{5}{4}[/tex]

Step 2: Substitute the values into the point-slope formula:

[tex]y - y1 = m(x- x1)[/tex]

Now that we know m = 5/4 , you can substitute this into the above formula and you get:

[tex]y - y1 = m(x- x1)[/tex]

[tex]y - (-1) = \frac{5}{4} (x - (-2)) \\y + 1 = \frac{5}{4} ( x + 2)[/tex]

[tex]y = \frac{5}{4}(x + 2) - 1[/tex]

Answer:

The value of m to be substituted in y – y1 = m(x – x1) is the negative reciprocal of the slope of the given line.

Substitute this in for m.

Substitute the given point, (x1, y1), in the point-slope form.

Isolate y by multiplying out m and subtracting y1 to rewrite the equation in slope-intercept form: y = mx + b.

Responder:

$ 2560

Explicación paso a paso:

Dado lo siguiente:

Importe total (A) = 60000

Pago inicial = 20% de A

Pago inicial = 0,2 * 60000 = 12000

Importe pendiente de pago = (60000 - 12000) = 48000

Calcular el interés simple sobre el saldo de 48000 = principal

principal * tasa * tiempo

(48 000 * 0,12 * (30/6))

48000 * 0,12 * 5 = 28800

Por tanto, el importe total a pagar durante 30 meses será:

(48 000 + 28800) = 76800

Dado que el pago mensual es fijo:

Pago mensual = (monto total a pagar / cantidad de meses)

Pago mensual = (76800/30)

Pago mensual = $ 2560

The first mistake is that she went from 3x-2 to 3x+2. Everywhere you see "3x+2", change it to "3x-2".

Another mistake is we shouldn't use absolute value in this case. This is because we're dealing with an odd number index. In this case, the index of the root in the original equation is 3. Because there isn't any absolute value, we won't have a plus/minus.

So we should have 3x-2 = 8 for the third to last step. That solves to x = 10/3 as the only solution.
