Step-by-step explanation:
The two men measure the angle of elevation to the highest point on the rock to be 22.6°. They
then walk 17 meters closer and measured the angle of elevation to be 38.3°. To the nearest meter,
how tall is Wave Rock?
You may not use Law or Sines to solve the problem.
Answer:
15 mStep-by-step explanation:
Refer to attached picture
The height = hAngles of elevation 22.6° and 38.3°Closer distance = dUse tangent to solve
tan 22.6° = h/(d + 17) ⇒ h = (d + 17) tan 22.6° ⇒ h = 0.42(d + 17)tan 38.3° = h/d ⇒ h = d tan 38.3° ⇒ h = 0.79dCompare the equations above and find the value of d:
0.42(d + 17) = 0.79d0.42d + 7.14 = 0.79d0.79d - 0.42d = 7.140.37 d = 7.14d = 7.14/0.37d = 19.3 mNow find the value of h:
h = 0.79dh = 0.79*19.3h = 15Wave Rock is 15 m tall
Amy ran 0.75 kilometers each day for 3 weeks. How many meters did she run over the 3 weeks?
Answer:
15,750 meters
Step-by-step explanation:
There are 1000 meters in a kilometer
.75 of a kilometer is 750 meters
There are 7 days in a week, 7x3 is 21.
750 x 21 = 15,750
Answer:
15750meters
Step-by-step explanation:
3 weeks=3x7
=21days
1day=0.75km
21days=21x 0.75
=15.75km
1km=1000m
15.75km=(1575/100 x 1000)m
=15750meters
Find the solution to the following system of equations using substitution or elimination y=-2x+7 y=3x-8
Answer:
x = 3, y = 1
Step-by-step explanation:
By substitution since y = -2x + 7, substitute that for the 2nd y so
-2x +7 = 3x - 8, so x = 3, then substitute the 3 in any of the equations, so y = -2(3) + 7 is equal to 1
If you use elimination you can subtract the two equations from each other to get rid of the y so
y = -2x + 7
-y = -3x + 8
so 0 = -5x + 15, 5x = 15, x=3

A. Micah will obtain a random sample by talking to as many surfers as possible.
B. The population for the survey is all people who surf at Breakers Point.
C Micah will not get a representative sample.
D.Micah's sample will be representative because anyone can surf at Breakers Point.
Answer:
B. The population for the survey is all people who surf at Breakers Point.
D.Micah's sample will be representative because anyone can surf at Breakers Point.
Step-by-step explanation:
hope it helps
The statements that are true are:
The population for the survey is all people who surf at Breakers Point.
Micah will not get a representative sample.
Options B and C are the correct answer.
What is random sampling?It is the way of choosing a number of required items from a population given.
Each item has an equal probability of being chosen.
We have,
A.
Micah will obtain a random sample by talking to as many surfers as possible.
This statement is not necessarily true as Micah may not be able to talk to all the surfers at Breakers Point during the time frame mentioned. Additionally,
Randomly selecting surfers would result in a better representation of the population.
B.
The population for the survey is all people who surf at Breakers Point.
This statement is true, as the population of interest is the surfers at Breakers Point.
C.
Micah will not get a representative sample.
This statement is also true, as the survey is conducted only between 8:00 A.M. and 12 P.M, which may not be representative of all surfers at Breakers Point.
Additionally, there may be bias in the sample if Micah only surveys surfers at a certain location or time period.
D.
Micah's sample will be representative because anyone can surf at Breakers Point.
This statement is not necessarily true as not all surfers may surf at the same time or location, or have the same level of experience or preference for surfboard style.
Thus,
The population for the survey is all people who surf at Breakers Point and
Micah will not get representative sample statements are true.

An angle measures 106.4° less than the measure of its supplementary angle. What is the measure of each angle
Answer:
The two supplementary angles are 10 and 170 degrees.
Step-by-step explanation:
Two angles are supplementary when that add up to 180 degrees. In this case, we are given that one of the two angles is 160 degrees more than the other. We can construct the following equation. x + ( x + 160 ) = 180 x
represents the degree measure of the smaller angle. Now, all we need to do is solve the equation for x. 2 x + 160 = 180 2 x = 20 x = 10
Now that we have the value of the smaller angle, we can easily solve for the larger angle. We are told that it is 160 degrees larger than the other one.
10 + 160 = 170. Therefore, the two supplementary angles are 10 and 170 degrees.
Find a quadratic polynomial with integer coefficients which has x = 2/9, ± SQRT23/9 as its real zeros.
Answer:
The quadratic polynomial with integer coefficients is [tex]y = 81\cdot x^{2}-36\cdot x -19[/tex].
Step-by-step explanation:
Statement is incorrectly written. Correct form is described below:
Find a quadratic polynomial with integer coefficients which has the following real zeros: [tex]x = \frac{2}{9}\pm \frac{\sqrt{23}}{9}[/tex].
Let be [tex]r_{1} = \frac{2}{9}+\frac{\sqrt{23}}{9}[/tex] and [tex]r_{2} = \frac{2}{9}-\frac{\sqrt{23}}{9}[/tex] roots of the quadratic function. By Algebra we know that:
[tex]y = (x-r_{1})\cdot (x-r_{2}) = x^{2}-(r_{1}+r_{2})\cdot x +r_{1}\cdot r_{2}[/tex] (1)
Then, the quadratic polynomial is:
[tex]y = x^{2}-\frac{4}{9}\cdot x -\frac{19}{81}[/tex]
[tex]y = 81\cdot x^{2}-36\cdot x -19[/tex]
The quadratic polynomial with integer coefficients is [tex]y = 81\cdot x^{2}-36\cdot x -19[/tex].

Which equation can be solved
Answer: Choice B) 2x-60 = 180
===========================================================
Explanation:
A bit of the question got cut off. I'm assuming the full question reads "In this diagram, the measure of angle RQS is 60 degrees less than the measure of angle PQS"
The portion underlined is the part cut off where I'm making the assumption. If that assumption is correct, then we have
angle PQS = xangle RQS = x-60Those two adjacent angles form a straight line of 180 degrees
(anglePQS) + (angleRQS) = 180
(x) + (x-60) = 180
2x-60 = 180
which points to choice B as the answer.
Answer:
Step-by-step explanation:
∠RQS = x - 60°
∠RQS = 180° - x
x - 60° = 180° - x
2x - 60° = 180°

what type of function is y=3x-2
Step-by-step explanation:
Explanation: y=3x+2 is not a function. Rather, it is just a regular linear equation.
It's not.
Explanation:
y=3x+2
is not a function. Rather, it is just a regular linear equation. However,
f(x)=3x+2
is a function, because it contains "
f(x)."
So, in general, if it contains " y ," then you are safe in assuming that it is an equation. If it contains "
f(x) ," then you are safe in assuming that it is a function.
I hope that helps!
The function y = 3x - 2 is a linear function.
Given data:
The function is represented as y = f ( x )
The value of y = 3x - 2
The equation y = 3x - 2 represents a linear function.
The function has a constant rate of change, which is 3, as the coefficient of x. The function forms a straight line when graphed on a Cartesian coordinate plane.
The term "linear" indicates that the relationship between x and y is of the first degree, meaning there are no exponents or other nonlinear components involved.

there 6 more girls than boys in a class there 44 students in the class in all how many boys are there
Answer: 28 boys and 16 girls
Step-by-step explanation: Divide 44 by 2 to get 22 subtract 22 by 6 to get the girls and add 6 to 22 to get the boys.
Answer:
44% of the students of a class are girls. If the number of girls is 6 less than the number of boys, how many students are there in the class?
let x be the number of boys, so (x - 6) will be number of girls.
total number of students will be boys plus girls : x + (x - 6) = 2x - 6
now 44% are girls which come from formula no. of girls divide by total students into 100: (x - 6)/(2x-6)*100 = 44
by solving we get x = 28 (where x is number of boys)
now x - 6 = 28–6 = 22 (number of girls)
add both we get total number of students = 28 + 22 = 50
Answer = 50
