Step-by-step explanation:

Since we arent given enough information to SOLVE for h, I will get as close as I can by rearranging the equation for h

Convert the fraction to a decimal for simplicity

A = 0.5(a + b)h

Divide both sides of the equals by 0.5

A/0.5 = (a + b)h

We can convert A/0.5 into its reciprocal

2 A = (a + b)h

Divide both sides of the equation by the bracketed (a + b)

(2 A)  /  (a + b) = h

3.5

Step-by-step explanation:

35% of 10 is the same thing as 0.35(10)

0.35 x 10 = 3 + (0.05 x 10) = 3 + 0.5 = 3.5

14/2 i think

Step-by-step explanation:

As the name of the test suggests, you have to compute the derivative:

[tex]f(x) = \dfrac1{2x+3} \implies f'(x) = -\dfrac2{(2x+3)^2}[/tex]

Find where, if at all, the derivative vanishes or is undefined - these are the critical points of f(x).

In this case, the derivative is never 0 since the numerator is constant and the denominator is non-negative. You also see that f '(x) is negative over its entire domain.

The denominator goes to 0 when 2x + 3 = 0, or x = -3/2.

Now split up the domain of f(x) into intervals with endpoints at the critical points. Here, we consider the two intervals, (-∞, -3/2) and (-3/2, ∞).

Take any point from either interval and check the sign of f '(x) at that point. Any points will do, but you should strive to pick one that makes calculations simple.

• From (-∞, -3/2), take x = -2; then f ' (-2) = -2 < 0. Since f '(x) is negative over this interval, f(x) is decreasing over it.

• From (-3/2, ∞), take x = 0; then f ' (0) = -2/9 < 0. Again, this means f(x) is decreasing over this interval.

So, the first derivative test tells us that f(x) = 1/(2x + 3) is decreasing over the intervals (-∞, -3/2) and (-3/2, ∞); in other words, over its entire domain.

For the second function, we have

[tex]f(x) = \dfrac{x+1}{x+3} \implies f'(x) = \dfrac{(x+3)-(x+1)}{(x+3)^2} = \dfrac2{(x+3)^2}[/tex]

Again, there's only one critical point, this time at x = -3 where the derivative is undefined.

• From the interval (-∞, -3), take x = -4; then f ' (-4) = 2 > 0, so f(x) is increasing.

• From the interval (-3, ∞), take x = 0; then f ' (0) = 2/9 > 0, so f(x) is increasing.

Answer:

$502.40

Step-by-step explanation:

Kristen works 38 hours for $6.80 per hour.

We multiply her pay and the hours she worked:

                   38 × 6.8 = 258.4

Thus, she makes $258.40/week

                   Now we add her tips, which would be the equation 258.4 + 224

     258.4 + 224 = 502.4

So, she made $502.40 in 1 week

Answer:

r = 8 and

s = -7

Step-by-step explanation:

(2r + 4s = - 12)/2 =

r +2s = -6

r = -2s - 6

Substitution:

6 (-2s -6) + 7s = -1

-12s - 36 + 7s = -1

-5s = 36-1

s = 35/-5

s = -7

6r + 7(-7) = -1

6r - 49 = -1

6r = 49-1

r = 48/6

r = 8

Answer:

  28/25

Step-by-step explanation:

To make the number into a fraction, multiply and divide by 100:

  1.12 × 100/100 = 112/100

Recognize that numerator and denominator have a factor of 4 in common:

  112/100 = 28×4/(25×4) = 28/25

The answer of the expression ab² + 2ab + a² for a = 6 and b = 3 will be 126 so option (b) will be correct.

A mixture of variables, numbers, addition, subtraction, multiplication, and division are called expressions.

An expression is a mathematical proof of the equality of two mathematical expressions.

A statement expressing the equality of two mathematical expressions is known as an equation.

Given the expression

ab² + 2ab + a²

Now,

a = 6 and b= 3

So,

⇒  6(3)² + 2(6)(3) + 6²

⇒  36 + 54 + 36

⇒ 126

Hence "The answer of the expression ab² + 2ab + a² for a = 6 and b = 3 will be 126".

Answer:

Line C is parallel to the given line.

Step-by-step explanation:

The given graph slopes down, and thus has a negative slope:  m = -1/2.

Of the possible choices, only C has this slope:  y = (-1/2)x + b.  The y-intercepts b and (0, 6) need not be the same, as the quality of parallelness is all that we care about here.

Oil floats on water because it is less dense I believe. So that would be the oil on top of the sauce(the oil is on top because of the water that was also added).

Answer:

30; -5 is 5 units away from 0 and V is 25 units away from 0, and 5 + 25 = 30.

Step-by-step explanation:

To find the distance between point T, which has a value of -5, and V, which has a value of 25, we should find the absolute value of each number and then add those numbers together.

So, the absolute value of -5 is 5 and the absolute value of 25 is 25. 25 + 5 = 30, and this is the length of TV.
