An altitude is drawn from the vertex of an isosceles triangle, forming a right angle and two congruent triangles. As a result, the altitude cuts the base into two equal segments. The length of the altitude is 26 inches, and the length of the base is 9 inches. Find the triangle’s perimeter. Round to the nearest tenth of an inch.
Answer:
The triangle's perimeter is 61.77 inches.
Step-by-step explanation:
Since an altitude is drawn from the vertex of an isosceles triangle, forming a right angle and two congruent triangles, and as a result, the altitude cuts the base into two equal segments, and the length of the altitude is 26 inches, and the length of the base is 9 inches, to find the triangle's perimeter the following calculation must be performed:
Isosceles triangle = 2 equal sides
To obtain the value of the sides, the Pythagorean theorem must be applied on the right triangle formed with the altitude.
(9/2) ^ 2 + 26 ^ 2 = X ^ 2
4.5 ^ 2 + 26 ^ 2 = X ^ 2
20.25 + 676 = X ^ 2
√ (20.25 + 676) = X
√696.25 = X
26.38 = X
26.3865 x 2 + 9 = X
52.77 + 9 = X
61.77 = X
Therefore, the triangle's perimeter is 61.77 inches.

Undefined geometric term that is described as two dimensional set of points that has no beginning or end
Answer:
Plane
Step-by-step explanation:
There are three undefined geometric terms:
1. Point: A point is just a location. It has no size.
2. Line: A line has no width and extends infinitely in one dimension.
3. Plane: A plane extends infinitely in two dimensions.
So the answer is plane.
Help pls, the question is in the picture. I'm to lazy to do the math today. I hate math.
Answer:
C
Step-by-step explanation:
Both models represent half of the gymnasium, its just that one is vertical and one is horizontal. Both are basically correct. C is the right answer since it says both models are correct. Each class also does occupy 1/12 of the gymnasium since they get 1/6 of 1/2 of the gymnasium. Of means multiply so 1/6 * 1/2 = 1/12.
F(x) = -3x-3 g(x) =2x^3+2
Find f(6) and g(-3)
Answer:
[tex]f(6)=-21\\\\g(-3)=-52[/tex]
Step-by-step explanation:
When given the following two functions,
[tex]f(x) =-3x-3\\g(x)=2x^3+2[/tex]
One is asked to evaluate the functions for, (f(6)) and (g(-3)). One can do this by substituting the values (6) into the function (f) and (-3) into the function (g). These values will replace the parameter (x).
[tex]f(6)=-3(6)-3\\[/tex]
Simplify,
[tex]f(6)=-18-3\\f(6)=-21[/tex]
Now repeat this process for the guncion (g(x)) to evaluate for (g(-3))
[tex]g(-3)=2(-3)^3+2[/tex]
Simplify,
[tex]g(-3)=2(-27)+2\\g(-3)=-54+2\\g(-3)=-52[/tex]
how do i solve 2/7v-1/7+14=20
Answer: 1: Combine multiplied terms into a single fraction
2: Multiply the numbers
3: Add the numbers
4: Solution
= 43/2
Step-by-step explanation:
Answer:
v = 43/2.
Step-by-step explanation:
2/7v - 1/7 + 14 = 20
2/7 v = 20 - 14 + 1/7
2/7 v = 6 1/7
2/7 v = 43/7
v = 43/7 / 2/7
v = 43/7 * 7/2
v = 43/2

Graded Assignment Unit Test, Part 2: More Math Models Answer the questions. When you have finished, submit this assignment to your teacher by the due date for full credit. Total score: ____ of 18 points (Score for Question 1: ___ of 10 points) 1. There are 400 rice weevils at the beginning of an insect study. The population is expected to grow at a rate of 150% each week. (a) Write and simplify a formula that can be used to predict the rice weevil population for any week after the beginning of the study. (b) Use the formula to predict the rice weevil population 10 weeks after the beginning of the study. Show your work. (c) Use the formula to predict when the rice weevil population will reach 1,000,000,000. Show your work. Answer:
Answer:
Y(n) = 400(2.5)^n
Y = 3,814,697 rice weevils
16.1 weeks
Step-by-step explanation:
To predict the population of rice weevil for any week after the start of the study ; wwe use an exponential function for this purpose :
y(n) = A(1 + r)^n
Where;
Y(n) = population at week n
r = growth rate ; n = number of weeks
A = initial population at the start of the study
r = 150% = 1.5
Hence, we have the equation :
Y(n) = 400(1 + 1.5)^n
Y(n) = 400(2.5)^n
B.)
Population after 10 weeks
n = 10
Y(10) = 400(2.5)^10
Y = 400 * 9536.7431640625
Y = 3814697.265625
Y = 3,814,697 rice weevils
C)
When population will reach 1,000,000,000
We have :
1,000,000,000 = 400(2.5)^n
1000000000 / 400 = 2.5^n
2500000 = 2.5^n
Take the log of both sides :
log(2500000) = nlog(2.5)
6.3979400 = n * 0.3979400
n = 6.3979400 / 0.3979400
n = 16.077649
n = 16.1 weeks approximately

The teacher of a statistics class records the heights (in inches) of his students and draws a box-and-whisker plot to look over the data collected. This box-and-whisker plot shows theresult. (a) What is the median height? (b) What is the range of heights?
Answer:
a) Median Height = 66 inches
b) Range of Heights = 18 inches
Step-by-step explanation:
a) The median in a box-and-whisker plot is the second quartile, located between the first and third quartiles indicated by the dashed line. Therefore, the median height is 66 inches.
b) The range in a box-and-whisker plot uses the same process of finding the range of a set of data. You find the difference between the maximum and the minimum values of the data. Therefore, the range of heights is 77 - 59 = 18 inches.
If t is time in hours, what does this function represent?
f(t) = 2.0.3^t
A. a 30-percent increase every hour
B. a 30-percent decrease every hour
C. a 70-percent decrease every hour
D. a 100-percent increase every hour
Answer:
C. a 70-percent decrease every hourStep-by-step explanation:
Given function:
f(t) = 2.0*(0.3)^tThis is exponential decay because:
0.3 = 1 - 0.7 = 100% - 70%and it represents 70% decrease every hour (if it is time in hours)

Problem 5
Answer: 6i------------------
Explanation:
We have these four identities
i^0 = 1i^1 = ii^2 = -1i^3 = -iNotice how computing i^4 leads us back to 1. So i^4 = i^0. The pattern repeats every 4 terms. So we divide the exponent by 4 and look at the remainder. We ignore the quotient entirely. We can see that 28/4 = 7 remainder 0. Meaning that i^28 = i^0 = 1.
We can think of it like this if you wanted
i^28 = (i^4)^7 = 1^7 = 1
Then the sqrt(-36) becomes 6i
So overall, we end up with the final answer of 6i
=============================================
Problem 6
Answer: -3i------------------
Explanation:
We'll use the ideas mentioned in problem 5
46/4 = 11 remainder 2
i^46 = i^2 = -1
sqrt(-9) = 3i
The two outside negative signs cancel out, but there's still a negative from -1 we found earlier. So we end up with -3i
In other words, here is one way you could write out the steps
[tex]-i^{46}*-\sqrt{-9}\\\\-i^{2}*-3i\\\\i^{2}*3i\\\\-1*3i\\\\-3i\\\\[/tex]
=============================================
Problem 7
Answer: -1------------------
Work Shown:
i^10 = i^2 because 10/4 = 2 remainder 2
i^19 = i^3 because 19/4 = 4 remainder 3
i^7 = i^3 because 7/4 = 1 remainder 3
Again, all we care about are the remainders.
[tex]i^{10}+i^{19} - i^{7}\\\\i^{2}+i^{3} - i^{3}\\\\i^{2}\\\\-1[/tex]
=============================================
Problem 8
Answer: -1 + i------------------
Work Shown:
i^22*i^6 = i^(22+6) = i^28
Earlier in problem 5, we found that i^28 = i^0 = 1
So,
[tex]i^1 - \left(i^{22}*i^{6}\right)\\\\i^1 - i^{28}\\\\i^1 - i^{0}\\\\i - 1\\\\-1+i[/tex]

The ratio of
420 m to 1 km =
Answer:
21:50
Step-by-step explanation:
We need to find the ratio of 420 m to 1 km.
We know that,
1 km = 1000 m
So,
The ratio becomes,
[tex]\dfrac{420\ m}{1\ km}=\dfrac{420\ m}{1000\ m}\\\\=\dfrac{42\ m}{100\ m}\\\\=\dfrac{21}{50}[/tex]
So, the required ratio is 21:50.

What's X in the diagram??
========================================================
Explanation:
Angles EGD and BGF are vertical angles. Both are unknown and equal to x.
Notice how angle AGD is adjacent to angle CGD. These two angles form a straight angle (180 degrees) and angle CGD is a right angle. That must mean AGD is also a right angle.
Angles AGE and EGD must add to 90 degrees since AGD is 90
----------
(angleAGE)+(angleEGD) = (angle AGD)
(30) + (x) = 90
x = 90-30
x = 60
