Answer:
b. maximum height: 5.6 ft
c. 0.3 sec to reach its maximum height
Step-by-step explanation:
y = -16x² + 10x + 4 ...(1)
d/dx: -32x + 10 = 0
x = 5/16 ≈ 0.3 ... plug in (1)
y = -16*(0.3)² + 10*0.3 + 4 = 5.56 ≈ 5.6

How many degrees did it change each minute?
pls i need help I'm confused.
Answer:
-6 degrees each minute
Step-by-step explanation:
if the temperature fell 48 degrees in 8 minutes, we must divide 48 by 8.
48 / 8 = 6
It fell 6 degrees every minute
Since we are talking about temperature dropping, it is negative
-6 degrees each minute
Answer:
It fell 6 degrees each minute
Step-by-step explanation:
I think you divide 48 by 8 so yeah it falls 6 degrees per minute if every fall is the exact same. You are welcome

how to find the area of a triangle with 2 lengths and 2 angles
Answer:
Below.
Step-by-step explanation:
Use the formula
Area = 1/2 ab sin C where a and b are the given lengths of 2 sides and < C is the angle between them.
If you are not given the value of < C you can calculate it from the other 2 known angles.

Lily swims a 100 meter race.She swims the first half in 27.8 seconds.She swims the second in 30.12 seconds.About how lkong does it take lily to win the whole race?Choose the best estimate.
Answer:
58 seconds
Step-by-step explanation:
100 meters in all
Exact calculations:
There are 2 half parts and first half in 27.8 seconds and second in 30.12 seconds so in all it took 27.8+30.12 = 57.92 seconds
Best estimates
27.8 ≈ 28
30.12 ≈ 30
Lily swims a 100 meter race in about 28+30 = 58 seconds

Select all the expressions that are equivalent to 4x + 5x + 6 − 5x − 4
A 4x + 2
B 4x +10
C 9x − 5x + 2
D 9x − 5x + 10
Answer:
A and C
Step-by-step explanation:
Let's begin with simplifying the first expression
4x + 5x + 6 − 5x − 4
After adding and subtracting like terms, you end up with:
4x + 2
A would be a correct answer because the expression provided in that letter is the same as the original expression
B would be wrong
C would be correct too, after subtracting like terms, you end up with 4x + 2
D would be wrong
Answer:
A 4x + 2
C 9x − 5x + 2
Step-by-step explanation:
To solve;
4x + 5x + 6 − 5x − 4
Collect like terms,
4x+5x-5x+6 - 4
9x-5x+2

The student's conclusion is incorrect because there is exactly one solution to the equation and this can be determined by using the arithmetic operations.
GIven :
A student concluded that 8x - 12 = 4( 1/2x - 6 ) has infinity many solutions.
The following steps can be used in order to determine the statement that describes the student's conclusion:
Step 1 - Write the given linear equation.
[tex]8x - 12 = 4 (\dfrac{1}{2}x-6)[/tex]
Step 2 - Simplify the above equation.
8x - 12 = 2x - 24
Step 3 - Subtract 2x on both sides in the above equation.
8x - 2x - 12 = 2x - 2x - 24
6x - 12 = -24
Step 4 - Add 12 on both sides in the above equation.
6x - 12 + 12 = 12 - 24
6x = -12
Step 5 - Divide by 6 on both sides in the above equation.
x = -2
Therefore, the correct option is B) The conclusion is incorrect because there is exactly one solution to the equation.
