Kelsea and Landon are playing in a park standing 100 feet away from each other. They both see a bird flying above them. The angles of elevation from each person to the bird are shown. How high is the bird from the ground? Round your answer to the nearest tenth.
Answers
Answer:
Step-by-step explanation:
use an ASA triangle with law of sine
since we know that 180 = 20 +45 + C .. solve for C = 115°
now use law of sines c/ sin(C) = b/sin(B) .. and solve for b
Sin(20)*100/sin(115) = b
b = 37.73774 ft
that's the hypotenuse of the 45 triangle
SOH CAH TOA to remember how trig functions fit
use b*Cos(45) = adj
26.6846 = adj
The bird is 26.7 ft. from the ground

What are the slope and y-inyercept of the line 4y=-x-32
Answers
First you'll have to bring the equation in form y = mx + b.
4y = -x - 32
y = -1/4 x - 8
So the slope is -1/4 and y-intercept is -8

Answer: (4x2 + 4x - 5) • (x - 1)
Step-by-step explanation: The Rational Root Theorem states that if a polynomial zeroes for a rational number P/Q then P is a factor of the Trailing Constant and Q is a factor of the Leading Coefficient
In this case, the Leading Coefficient is 4 and the Trailing Constant is 5.
The factor(s) are:
of the Leading Coefficient : 1,2 ,4
of the Trailing Constant : 1 ,5
The Factor Theorem states that if P/Q is root of a polynomial then this polynomial can be divided by q*x-p Note that q and p originate from P/Q reduced to its lowest terms
In our case this means that
4x3-9x+5
can be divided with x-1
2.2 Polynomial Long Division
Dividing : 4x3-9x+5
("Dividend")
By : x-1 ("Divisor")
dividend 4x3 - 9x + 5
- divisor * 4x2 4x3 - 4x2
remainder 4x2 - 9x + 5
- divisor * 4x1 4x2 - 4x
remainder - 5x + 5
- divisor * -5x0 - 5x + 5
remainder 0
Quotient : 4x2+4x-5 Remainder: 0
2.3 Factoring 4x2+4x-5
The first term is, 4x2 its coefficient is 4 .
The middle term is, +4x its coefficient is 4 .
The last term, "the constant", is -5
Step-1 : Multiply the coefficient of the first term by the constant 4 • -5 = -20
Step-2 : Find two factors of -20 whose sum equals the coefficient of the middle term, which is 4 .
-20 + 1 = -19
-10 + 2 = -8
-5 + 4 = -1
-4 + 5 = 1
-2 + 10 = 8
-1 + 20 = 19
Observation : No two such factors can be found !!
Conclusion : Trinomial can not be factored

To get on a certain toll road a driver has to take a card that lists the mile entrance point. The card also has a timestamp. When going to pay the toll at the exit, the driver is surprised to receive a speeding ticket along with the toll. Explain how this can happen.
Answers
Answer:
Step-by-step explanation:
This can happen because of the timestamp on the toll card. When you pass through the initial entrance point the timestamp marks the exact moment you passed. When you pass through the exit toll point the individual subtracts the current time from the time you entered the initial toll entrance. From this, he can easily determine the average speed that you were driving at. If the average speed is higher than the speed limit, it means that at some point between the two toll booths you were speeding and therefore they can give you a speeding ticket.

For the function f(x) = 2x - 9, find the following
a. f(0)
b. f(2)
c. f(-3)
d. f(1/2)
Answers
Answer:
a) f(0) = -9
b) f(2) = -5
c) f(-3) = -15
d) f(1/2)=-8
Step-by-step explanation:
We are given the function [tex]f(x)=2x-9[/tex] and we need to find the following:
a) f(0)
For finding f(0) put x =0 in the given function
[tex]f(x)=2x-9\\Put\:x=0\\f(0)=2(0)-9\\f(0)=-9[/tex]
So, we get f(0)=-9
b) f(2)
For finding f(2) put x =2 in the given function
[tex]f(x)=2x-9\\Put\:x=2\\f(2)=2(2)-9\\f(2)=4-9\\f(2)=-5[/tex]
So, we get f(2)=-5
c) f(-3)
For finding f(-3) put x =-3 in the given function
[tex]f(x)=2x-9\\Put\:x=-3\\f(-3)=2(-3)-9\\f(-3)=-6-9\\f(-3)=-15[/tex]
So, we get f(-3)=-15
d) f(1/2)
For finding f(1/2) put x =1/2 in the given function
[tex]f(x)=2x-9\\Put\:x=\frac{1}{2}\\f(\frac{1}{2})=2(\frac{1}{2})-9\\f(\frac{1}{2})=1-9\\f(\frac{1}{2})=-8[/tex]
So, we get f(1/2)=-8
b. Consider a large population of turtles in which 30% of the population are snapping turtles and 70% of the population are box turtles. What is the value of the diversity index D for the population
Answers
Answer: the value of the diversity index D for the population is 0.42
Step-by-step explanation:
Given that; population of the two species are
p1 = 30% = 0.3 (snapping turtle)
p2 = 70% = 0.7 ( box turtle)
so if two (2) organisms are picked, then they can be different from each other ( i.e Event E) under following two scenarios
E1 → First organism selected from p1 and second organism selected from p2
E2 → First organism selected from p2 and second organism selected from p1
which means we are observing the different orders in which the organisms can be picked.
So the probability of event E = the sum of probabilities of events E1 and E2.
which is;
D = P(E) = P(E1) + P(E2)
= P1×P2 + P2×P1
= 2P1P2
so we substitute
D = 2 × 0.3 × 0.7
D = 0.42
Therefore the value of the diversity index D for the population is 0.42

A recipe for chocolate chip cookies mixes 5 1/2 cups of cookie dough with 3/4 cup of chocolate chips to make 48 cookies. A baker has 3 cups of chocolate chips in the pantry and uses them all to make cookies using the proportions of the recipe.
How many cups of cookie dough does the baker use?
A. 12 3/8 cups
B. 16 1/2 cups
C. 21 cups
D. 22 cups
Answers
Answer:
He makes 4 batches of cookies with all of the chocolate chips so he will use 4 times the amount of batter in 1 batch so you would do 5 1/2 times 4 which eqauls 22 so he will use 22 cups of cookie dough.
So your answer is D. 22 cups
Step-by-step explanation:
The number of cups of cookie dough does the baker use is 22 cups.
Given that,
A recipe for chocolate chip cookies mixes 5 and a half cups of cookie dough with 3by 4 cup of chocolate chips to make 48 cookies. A baker has 3 cups of chocolate chips in the pantry and uses them all to make cookies using the proportions of the recipe.Based on the above information, the calculation is as follows:
[tex]= 5\frac{1}{2} \times 4\\\\= \frac{11}{2}\times 4[/tex]

Consider the functions f(x) = (4/5)x and g(x) = (4/5)x + 6. What are the ranges of the two functions?

Answers
Answer:
0
6
Step-by-step explanation:
<3
The ranges are:
f(x): {y | y ≤ infinity}
g(x): {y | y ≤ infinity}
What is a function?A relation between a collection of inputs and outputs is known as a function. A function is a connection between inputs in which each input is connected to precisely one output. Each function has a range, co-domain, and domain.
For the function f(x) = (4/5)x, any input value of x will be multiplied by 4/5 and produce a corresponding output value y.
Since the fraction 4/5 is less than 1, the output values of f(x) will always be smaller than the input values of x.
Therefore, the range of f(x) will be all real numbers less than or equal to the greatest possible output value.
The greatest possible output value will occur when x is the greatest possible input value, which is infinity. So, the range of f(x) is:
f(x): {y | y ≤ infinity}
For the function g(x) = (4/5)x + 6, any input value of x will be multiplied by 4/5, then 6 will be added to the result to produce a corresponding output value y.
The fraction 4/5 is less than 1, so the output values of g(x) will always be less than the input values of x plus 6.
Therefore, the range of g(x) will be all real numbers less than or equal to the greatest possible output value, which occurs when x is infinity. So, the range of g(x) is:
g(x): {y | y ≤ infinity}

B. k=5
C. k=-1/5
D. k= -5

Answer:
b is the answer
Step-by-step explanation:
the graph of f(x)=0.5x is replaced by the graph of g(x) = 0.5x-k
if g(x) is obtained by shifting f(x) down by 5 units,
then the graph of f(x) = 0.5x is replaced by the graph of g(x) = 0.5x-5
so k = 5 units

1.How do you dilate a figure on the coordinate plane?
2. What is scale factor?
3. What are the properties of similar figures (what do they have congruent and/or proportional)?
Answers
Answer:
1. To dilate something in the coordinate plane, multiply each coordinate by the scale factor. This is called mapping. For any dilation the mapping will be \begin{align*}(x, y) \rightarrow (kx, ky)\end{align*}. In this Concept, the center of dilation will always be the origin, unless otherwise stated.
2. When using State Plane coordinates the scale factors, also known as the K factors, are ratios that can be used as multipliers to convert ellipsoidal lengths, also known as geodetic distances, to lengths on the map projection surface, also known as grid distances, and vice versa.
3.Similar figures have the same shape (but not necessarily the same size) and the following properties: Corresponding sides are proportional. That is, the ratios of the corresponding sides are equal. Corresponding angles are equal.
