I recommend using a calculator, but working out the problem manually is alright too. Be sure to check your answer to make sure it's correct by looking over your work or by multiplying two of the numbers to see if it equals the third. The answer is about .92.

Yes, Bryan is correct.

Because 4 is in the hundreds place.

The value of a digit in the number is the digit multiplied by the place value.

What are the coordinates of the vertex of the function f(x)=x^2+10x−3? (–5, –28) (–5, 28) (5, –28) (5, 28)

polet [3.4K]

Answer:

(-5,-28)

Step-by-step explanation:

Given

$f(x)=x^2+10x - 3$

Required

Find the coordinates of the vertex

Given that the function is a quadratic function;

The general form of a quadratic function is

$f(x)= ax^2+bx +c$

By comparison;

$a = 1\ b = 10\ and\ c = -10$

To calculate the coordinates of the vertex;

we start by calculating the x-coordinate;

$x = \frac{-b}{2a}$

Substitute 10 for b and 1 for a

$x = \frac{-10}{2*1}$

$x = \frac{-10}{2}$

$x = -5$

Substitute $x = -5$ in the given function;

$y=x^2+10x - 3$

$y=(-5)^2+10*-5 - 3$

$y=25-50 - 3$

$y=-28$

<em>Hence, the coordinates of the vertex is (-5,-28)</em>

Find the image of the given point under the given translation!!!! help please!!!!

harkovskaia [24]

Answer:

P' = (7, - 8)

Step-by-step explanation:

Under the given translation (x + 4, y - 3)

Add 4 to the x- coordinate of P and subtract 3 from the y- coordinate of P

P' = (3 + 4, - 5 - 3 ) = (7, - 8)

What are the units for the variable in the following scenario?

krek1111 [17]

Answer:

Her grocery bill was <u>$4.62</u>.

Step-by-step explanation:

There is some mistake in question so the correct question is:

Sherry bought 6 apples at 43¢ per apple. She then bought 4 oranges at 51¢ per orange. How much was her grocery bill?

Now, to find the grocery bill.

As the units are given:

<em>43¢ per apple and </em>

<em>51¢ per orange.</em>

$1 = 100¢.

So, the cost of 6 apples = $0.43\times 6=2.58$

Thus, the cost of 6 apples = $2.58

And the cost of 4 oranges = $0.51\times 4=2.04$

Thus the cost of 4 oranges = $2.04

Now, to get the total grocery bill we add the cost of apples and oranges:

$\$2.58+\$2.04$

$=\$4.62$

Therefore, her grocery bill was $4.62.
