Answer: $f(-735) = -\frac{2}{3}(-735) + 490 = 980$

Step-by-step explanation:

$f(x) = -\frac{2}{3} x + 490 =0$ Subtract 490 from both sides

$\frac{3}{2}* -\frac{2}{3} x = -490 *\frac{3}{2}$ Then flip $-\frac{2}{3}$ multiply both sides by $\frac{3}{2}$ to cancel out $-\frac{2}{3}$

$x= -735$ Thus giving you -735 as your $x$ .

Then you plug it back into the equation to solve.

The sum of 139 and the product of a number raised to the third power and 17. In symbols, the phrase is written as.

Answer:

Step-by-step explanation:

The word "sum" means the amount resulting from addition in an equation. This means that we are adding all of these numbers together.

The word "product" means the amount resulting from multiplication in an equation, this means we need to find the product of a number multiplied by itself three times. Since we don't know what number it is, we can use the variable 'x'.

So, you would be adding 139, the product of x³, and 17, which would be written as y = 139 + x³ + 17.

n200080 [17]

Answer:

1) Between 0 and 1 minute the rate of change is 25 ft./min

2) Between 1 and 2 minute the rate of change is 0 ft./min

3) Between 2 and 4 minute the rate of change is -12.5 ft./min

Step-by-step explanation:

1) Between 0, and 1 feet, we have;

The rate of change = (Final height - Initial height)/(Final time - Initial time)

The rate of change = (40 - 15)/(1 - 0) = 25 ft/min

Between 0 and 1 minute the rate of change = 25 ft./min

2) Between 1, and 2 feet, we have;

The rate of change = (40 - 40)/(2 - 1) = 0 ft/min

Between 1 and 2 minute the rate of change = 0 ft./min

3) Between 2, and 4 feet, we have;

The rate of change = (15 - 40)/(4 - 2) = -12.5 ft/min

Between 2 and 4 minute the rate of change = -12.5 ft./min

Answer:

see below

Step-by-step explanation:

9 ^-5 * 9^-3

When multiplying these we ADD the exponents:

9^-5 * 9^-3

= 9^(-5 + -3)

= 9 ^-8

= 1/9^8 Option A

2. 2^14 / 2^7 This is a division so we SUBTRACT the exponents:-

= 2^(14 - 7)

= 2^7 (answer)

3. If the triangle is a right angled one then it will obey Pythagoras Theorem so:-

13^ = x^2 + 5&2

x^2 = 13^2 - 5^2

x^2 = 144

x = 12 (answer)

4. The last choice is a crucial step.

The total area of the triangles is the same in both large squares so the area of the large square e^2 = a^2 + b^2 ( the 2 squares in the left side large square).
