By using the Pythagoras theorem, the length of the ladder will be 13.6 feet.
<h3>What is a Pythagoras theorem?</h3>
The Pythagoras theorem states that the sum of two squares equals the squared of the longest side.
The Pythagoras theorem formula is given as
H² = P² + B²
Jennifer needs to use a ladder to clean a second-floor window on a building.
If the window is 13 ft above the ground and the base of the ladder is 4 ft from the building.
Then the length of the ladder will be
H² = 13² + 4²
H² = 169 + 16
H² = 185
H = 13.6 ft

None of these are true roots.
a. The closest true root to √50 is 7.
7^2 = 49
b. The closest true root to √150 is 12.
12^2 = 144
c. The closest true root to √350 is 19.
19^2 = 361
d. This is a cubed root, rather than a square root.
The closest root to 3√350 is 7.
7^3 = 343
Answer:
Type 2 Error
Step-by-step explanation:
Null Hypothesis [H0] : New soybean has no impact on harvest
Alternate Hypothesis [H1] : New soybean leads to larger harvest
The farmer accepts the null hypothesis & concludes, that there is no impact of new soybean on harvest.
He could have committed Type 2 Error, which refers to accepting a null hypothesis when it is actually false.
Answer:
f(x) = -4x² - 24x - 38
Step-by-step explanation:
f(x )= -4(x + 3)² – 2
Expand the squared term
f(x) = -4 (x² + 6x + 9) - 2
Distribute the -4
f(x) = (-4x² - 24x - 36) - 2
Combine like terms
f(x) = -4x² - 24x - 38
5 1/2 - 3 1/4
11/2 - 13/4
22/4 - 13/4 = 9/4
your answer is 2 1/4
hope this helps
