Answer:

y = 3x^2 + 2 is shifted up two units compared to y = 3x^2

Step-by-step explanation:

The graph of y = 3x^2 + 2 is different from the graph of y = 3x^2 in that the first equation has a + 2. This plus two means that the graph of the parabola for this equation will be shifted up 2 units compared to the graph of the parabola for the second equation.

Answer:

$a \\ \frac{50}{0.25} = 200 \: \frac{km}{ {h}^{2} } \\ b \\ the \: area \: under \: graph = whole \: distance = \\ = 50 \times (2 + 1.5) \times 0.5 + \\ + 50 \times (0.5 + 1) \times 0.5 = 125km \\ c \\ \ \: average \: speed \: = \frac{125}{2} = 62.5 \frac{km}{h}$

A circle with a centre 0, has an equation x2 + y2 = 25

GaryK [48]

The linear equation of the tangent at point A is given by:

$y = \frac{-4x + 25}{3}$

<h3>What is a linear function?</h3>

A linear function is modeled by:

y = mx + b

In which:

m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.

b is the y-intercept, which is the value of y when x = 0, and can also be interpreted as the initial value of the function.

In this problem, to find the slope, we need to find the derivative at (4,3), using implicit differentiation. Hence:

$2x\frac{dx}{dx} + 2y\frac{dy}{dx} = 0$

$\frac{dy}{dx} = -\frac{x}{y}$

$\frac{dy}{dx} = -\frac{4}{3}$

Then:

$y = -\frac{4}{3}x + b$

We use point (4,3) to find b, hence:

$y = -\frac{4}{3}x + b$

$3 = -\frac{16}{3} + b$

$b = \frac{25}{3}$

Hence, the equation is:

$y = \frac{-4x + 25}{3}$

During the basketball season, Cory made 21 of the 60 baskets she attempted. Krista made 16 out of 40 baskets she attempted. Paul

Bas_tet [7]

Given:

Cory made 21 of the 60 baskets she attempted.

Krista made 16 out of 40 baskets she attempted.

Paul made 17 of the 50 baskets she attempted.

Sally 11 of the 55 she attempted.

To find:

Who had the greatest percentages of baskets made?

Solution:

We know that,

$\text{Percentage of baskets made}=\dfrac{\text{Baskets made}}{\text{Total attempts}}\times 100$

Using this formula, we get

$\text{Cory's percentage of baskets made}=\dfrac{21}{60}\times 100=35\%$

$\text{Krista's percentage of baskets made}=\dfrac{16}{40}\times 100=40\%$

$\text{Paul's percentage of baskets made}=\dfrac{17}{50}\times 100=34\%$

$\text{Sally's percentage of baskets made}=\dfrac{11}{55}\times 100=20\%$

From the above percentages 40% is maximum.

Therefore, Krista has greatest percentage of baskets made.

Morgan lives in Austin, Texas, and lost his job when his company decided to reorganize. He had worked there for 3 years, and he

CaHeK987 [17]

Answer:

$455

Step-by-step explanation:

Minimum unemployment benefit in Texas is $69 per week and the maximum is $521.

In order to determine unemployment benefits in Texas, you must first calculate total earnings for the last quarter = 13 x $1,750 x 1/2 = $11,375

Now, you divide that amount by 25, so $11,375 / 25 = $455. Since that amount is below the maximum unemployment benefit per week, then Morgan is going to receive $455.
