Answer:what grade math is this
Step-by-step explanation:
Answer:
f(x) = -7(x - 2)^2 +3
Step-by-step explanation:
Vertex form is f(x) = a(x - h)^2 + k. plugin -4 for f(x). leave the variable a. plugin 1 for x and 2 for h. Lastly, plug in 3 for k. Then slove the expression for a. Once you find a plug it in for the a variable, plug 2 in for the h and plug 3 in for the k.

How do I simplify radicals?
Answers
Answer:
Step 1: Find the prime factorization of the number inside the radical. Start by dividing the number by the first prime number 2 and continue dividing by 2 until you get a decimal or remainder. Then divide by 3, 5, 7, etc. until the only numbers left are prime numbers. Click on the link to see some examples of Prime Factorization. Also factor any variables inside the radical.
Step 2: Determine the index of the radical. The index tells you how many of a kind you need to put together to be able to move that number or variable from inside the radical to outside the radical. For example, if the index is 2 (a square root), then you need two of a kind to move from inside the radical to outside the radical. If the index is 3 (a cube root), then you need three of a kind to move from inside the radical to outside the radical.
Step 3: Move each group of numbers or variables from inside the radical to outside the radical. If there are nor enough numbers or variables to make a group of two, three, or whatever is needed, then leave those numbers or variables inside the radical. Notice that each group of numbers or variables gets written once when they move outside the radical because they are now one group.
Step 4: Simplify the expressions both inside and outside the radical by multiplying. Multiply all numbers and variables inside the radical together. Multiply all numbers and variables outside the radical together.
Example:
Example 1 – Simplify: Example 1
Step 1: Find the prime factorization of the number inside the radical.
252=2*2*3*3*7
Step 2: Determine the index of the radical. In this case, the index is two because it is a square root, which means we need two of a kind.
√252= √2*2*3*3*7
Step 3: Move each group of numbers or variables from inside the radical to outside the radical. In this case, the pair of 2’s and 3’s moved outside the radical.
2*3√7
Step 4: Simplify the expressions both inside and outside the radical by multiplying.

Answers
Answer:
When multiplying the same base raised to an exponent, keep the base and add the exponents.
Step-by-step explanation:
The exponent "product rule" tells us that, when multiplying two powers that have the same base, you can add the exponents. In this example, you can see how it works. Adding the exponents is just a short cut! The "power rule" tells us that to raise a power to a power, just multiply the exponents.

Step-by-step explanation:
A submarine is exploring the Pacific Ocean. At 502.5 feet below sea level, the water temperature is 63 1/4°F. The submarine dives down 115 feet deeper, and the water temperature drops by 2 1/5 °F. What were the elevation and the water temperature after the submarine dove? Assume that sea level is at 0 feet of elevation.
Write an expression to represent the water temperature after the submarine’s final dive. Then simplify the expression to find the temperature.
Answers
Answer:
At the elevation 617.5 feet below the sea level temperature of the water was 61\frac{1}{20}°F
Step-by-step explanation:
At 502.5 feet below the sea level temperature of the water is 63\frac{1}{4}°F
When submarine dives down 115 feet deeper, water temperature drops by 2\frac{1}{5}°F
Elevation after the submarine dove = -502.5 - 115 = -617.5 feet
This negative sign represents the elevation below the sea level.
And the temperature will be = 63\frac{1}{4}-2\frac{1}{5}
= \frac{253}{4}-\frac{11}{5}
= \frac{1265-44}{20}
= \frac{1221}{20}
= 61\frac{1}{20}°F
Therefore, at the elevation 617.5 feet below the sea level temperature of the water was 61\frac{1}{20}°F
The required expression is y = 0.01x + 58.2. Where, x = level of sea and y = temperature. At 115 feet deeper temperature is 61 1/4°F.
A submarine is exploring the Pacific Ocean. At 502.5 feet below sea level, the water temperature is 63 1/4°F.
It is the relationship between sets of values. e g y=f(x),
Here, assume that relation ship between temperature and sea level is linear. So the expression can be calculated as y = - 0.01x + 58.2.
Since at 115 feet deeper from 502.5 temperature-
total sea level; = 502.5+115
= 617.5
Put it in expression
y = -0.01 * 617.5 + 68.2
y = 61.25
y = 61 1/4 °F
Thus, the required expression is y = 0.01x + 58.2. Where, x = level of sea and y = temperature. At 115 feet deeper temperature is 61 1/4°F.
