Tyler is observing the ascent of a
steel beam being lifted by a crane
from a position about 250 feet
away. What function models the
height h in feet of the beam as a
function of the angle of inclination
from Tyler's position to the steel
beam?
Answer:
Step-by-step explanation:
tanθ = h/250
h = 250tanθ
The height h in feet of the beam as a function of the angle of inclination from Tyler's position to the steel beam is h = 250 tanθ feet
What is angle of inclination?"The angle inclination of a line is the angle formed by the intersection of the line and the x-axis."
What are trigonometric functions?"The trigonometric functions are real functions which relate an angle of a right-angled triangle to ratios of two side lengths."
We have
Adjacent side = 250 feet
From the figure,
We can write trigonometric function
Tanθ = [tex]\frac{AB}{BC}[/tex]
Tanθ = [tex]\frac{h}{250}[/tex]
⇒ h = 250 tanθ feet
Hence, The height h in feet of the beam as a function of the angle of inclination from Tyler's position to the steel beam is h = 250 tanθ

I will mark you brainliest if you get the question right
Answer:
the answer of this question is
x+13+10x+13+2x-2=180
13x+24=180
13x=156
x=12
q=10.12+13
123
Answer:
P = 25
Q = 133
R = 22
Step-by-step explanation:
x + 13 + 10x + 13 + 2x - 2 = 180 add x's
13x + 13 + 13 - 2 = 180 add number's on left
13x + 24 = 180 subtract 24 from both sides
13x = 156 divide both sides by 13
x = 12
x + 13 = 12 + 13 = 25
10x + 13= 10(12) + 13 = 133
2x -2 = 2(12) - 2 = 22

Answer:
A) h= 201-6t
B) Candle B is 290 millimeters tall and burns at 5 millimeters per hour
C) Candle A burns faster because it has a rate of burning that is 1 millimeter faster per hour than Candle B (coefficient in front of t)
D) 58 hours
Step-by-step explanation:
Candle A Went down 24 in 4 hours so thats 6 millimeters per hour.
A) h= 201-6t
Candle A Went down 24 in 4 hours so thats 6 millimeters per hour (how i found the coeffiecient in front of t.)
B) Candle B is 290 millimeters tall and burns at 5 millimeters per hour
(Just interpreted the given equation)
C) Candle A burns faster because it has a rate of burning that is 1 millimeter faster per hour than Candle B, although candle B is still 50% larger than candle A at the beginning of burning.
D) 290=5t
t=58 hours
It would take 58 hours for Candle B to burn down completely, from the given equation.

What is the equation of the polynomial function shown on the graph?
Answer:
-(x+4)(x+1)(x-3).
Step-by-step explanation:
Let find the roots of the polynomial function. Roots are the x intercept( what is the value of x when y=0)
The roots are -4,-1,and 3. We can represent that as
(x+4)(x+1)(x-3)
This is a negative polynomial so we will reflect it across the x axis by putting a negative sign in front of the roots.
-(x+4)(x+1)(x-3).
A recent study revealed that the average weight of babies born in the US is normally distributed with a mean of 7.5 pounds. One researcher decides to look at the age of the mother to determine if younger mothers have babies that are significantly heavier or lighter than average. The researcher collects data from 87 babies who were born to mothers between the ages of 16 and 18. The average weight for these babies was 7.3 pounds with a standard deviation of .6 pounds. Which of the following statements is relevant to the assumption of Appropriate Measurement of the Variables?
a. the standard deviation for young mothers is not expected to be different than the standard deviation in the population
b. only one baby was measured per mother
c. weights of babies are normally distributed in the population
d. the study used a sample that is different than the comparison population and measured weight on a ratio scale
Answer:
c. Weights of babies are normally distributed
Step-by-step explanation:
The research has been conducted to identify the weight of new born babies in comparison to the weight of their mother. The samples are collected from young mothers who are at age of 16 to 18. The babies average weight turned out to be 7.3 pounds. It is assumed that the weight of babies is normally distributed.
