8 0

Order is operation is PEMDAS which means Parentheses, Exponents Mulitiplication,division,Addition and Subtraction so you follow the order whether they exist or not.

So (41-3^2)-(4+4)=

41-9-8 = 32-8 = 24

Tiffany took out a total of $10,000 in subsidized Stafford loans for her four-year college education. How much interest that acc

Alexxandr [17]

Answer:

$2,400

Step-by-step explanation:

First, converting R percent to r a decimal

r = R/100 = 6%/100 = 0.06 per year,

then, solving our equation

I = 10000 × 0.06 × 4 = 2400

I = $ 2,400.00

The simple interest accumulated

on a principal of $ 10,000.00

at a rate of 6% per year

for 4 years is $ 2,400.00.

A line includes the points (8,5) and (9, – 5). What is its equation in point-slope form?

zmey [24]

Answer:

Step-by-step explanation:

slope = $\frac{y_{2}-y_{1}}{x_{2}-x_{1}}$

$=\frac{-5-5}{9-8}\\\\=\frac{-10}{1}\\\\=-10\\$

Point-slope form:

y - y1 = m(x - x1)

y - 5 = -10(x - 8)

Find the equation of a circle in standard form that is tangent to the line x = -3 at (-3, 5) and also tangent to the line x = 9.

Sedaia [141]

Answer:

(x -3)² +(y -5)² = 36

Step-by-step explanation:

The center is on the vertical line halfway between the given vertical lines, so is at x=3. It is also on the horizontal line through the point (-3, 5), so is at y=5. The center is 9-3=6 from either tangent line, so this is the radius.

For center (h, k) and radius r, the circle's equation is ...

(x -h)² +(y -k)² = r²

For (h, k) = (3, 5) and r=6, the equation is ...

(x -3)² +(y -5)² = 36 . . . . . . . . does not match any choice written here
