Answer:

The quotient of: \frac{2.64\cdot 10^{-3}}{8.0\cdot 10^0} is: \mathbf{3.3\times 10^{-4}}

Step-by-step explanation:

We need to find quotient of: \frac{2.64\cdot 10^{-3}}{8.0\cdot 10^0}

We know that 10^0=1

Now solving:

\frac{2.64\cdot 10^{-3}}{8.0\cdot 10^0}\\=\frac{2.64\cdot 10^{-3}}{8.0}\\=\frac{0.00264}{8}\\=0.00033

Writing it in scientific notation

0.00033\\=3.3\times10^{-4}

So, the quotient of: \frac{2.64\cdot 10^{-3}}{8.0\cdot 10^0} is: \mathbf{3.3\times 10^{-4}}

Which of the following equations represents a line that is perpendicular to y=-4x+9 and passes through the point, (4,5)?
kap26 [50]

Answer:

y = \frac{1}{4}x + 4 \\or\\4y = x + 16

Step-by-step explanation:

Given equation of line is:

y = -4x+9

Comparing it with the standard form

y = mx+b

m = -4

As we know that the product of slopes of perpendicular lines is -1

Let m1 be the slope of perpendicular line

m * m1 = -1

-4 * m1 = -1

m1 = -1/-4

m1 = 1/4

In order to find the value of b, putting the point in standard form

5 = (1/4)*4 + b

5 = 1 + b

b = 5-1

b = 4

Putting the value of b and m1 in standard form

y = \frac{1}{4}x + 4 \\or\\4y = x + 16 ..

PLEEASE HELP!!!! I WILL GIVE BRAINLIEST!!!!!
Vika [28.1K]

Answer:

7

Step-by-step explanation:

Set up an equation using slope intercept form.

y = mx + b

75 = 8x + 15

Solve.

75 = 8x + 15

-15          -15

60 = 8x

7.5

Round down as it is dealing with money and he would not have enough to purchase an 8th grocery.

7 is the final answer.

Hope this helps!
