Given ASTU and ADEF,
what is mZD? what is m/T?
Please help
Answers
Answer:
m ∠D = 29°
m ∠T = 105°
Step-by-step explanation:
Given: ΔSTU and ΔDEF
To find: m ∠D and m ∠T
Solution:
According to SSS similarity criteria,
two triangles are said to be similar if their corresponding sides are proportional.
In ΔSTU and ΔDEF,
[tex]\frac{ST}{DE}=\frac{15}{6}=\frac{5}{2} \\\\\frac{TU}{EF}=\frac{10}{4}=\frac{5}{2}\\\\\frac{SU}{DF}=\frac{20}{8}=\frac{5}{2}[/tex]
So,
[tex]\frac{ST}{DE}=\frac{TU}{EF}=\frac{SU}{DF}=\frac{5}{2}[/tex]
Therefore,
ΔSTU ≈ ΔDEF
If two triangles are similar then measure of their corresponding angles are equal.
m ∠D = m ∠S = 29°
m ∠U = m ∠F = 46°
In ΔSTU,
m ∠S + m ∠T + m ∠U = 180°
29° + m ∠T + 46° = 180°
75° + m ∠T = 180°
m ∠T = 180° - 75° = 105°
(According to angle sum property of a triangle, sum of measures of angles of a triangle is equal to 180°)

The sum of two numbers is 79,and their difference is 33
Answers
Answer: infinite answers, jk there is like a lot tho
Step-by-step explanation: The sum of x and y is 79. In other words, x plus y equals 79 and can be written as equation A:
x + y = 79
The difference between x and y is 23. In other words, x minus y equals 23 and can be written as equation B:
x - y = 23
Now solve equation B for x to get the revised equation B:
x - y = 23
x = 23 + y
Then substitute x in equation A from the revised equation B and then solve for y:
x + y = 79
23 + y + y = 79
23 + 2y = 79
2y = 56
y = 28
Now we know y is 28. Which means that we can substitute y for 28 in equation A and solve for x:
x + y = 79
x + 28 = 79
X = 51
Summary: The sum of the two numbers is 79 and their difference is 23. What are the two numbers? Answer: 51 and 28 as proven here:
Sum: 51 + 28 = 79
Difference: 51 - 28 = 23

Complete the statement by filling in the blanks. The null hypothesis H0 is the statement of _________ and always has a ______ sign. The alternative hypothesis Ha is the __________ hypothesis. It is a statement about the value of a __________ that we intend to test. Group of answer choices
Answers
Answer:
No change ; = ; research ; parameter
Step-by-step explanation:
The Null hypothesis in a statistical test is always the initial truth which always means that a research scenario or statement is as it is or that there is no change whatsoever. The null hypothesis is usually denoted as H0 ; because it is always the initial truth or accepted claim, it usually takes a equal to sign, this denotes that, there is no change in parameter, either the population mean or any other statistical measure we wish to test. The alternative hypothesis on the other hand always negated the null hypothesis, because it brings up a claim which is to check or peruse the Null hypothesis, hence, it is a research hypothesis, denoted as Ha: ;
The alternative hypothesis contains the statement about the population parameter we wish to test( parameter is a measured value about the population).

-4.5 + 4.2x + 23.1 = 3x
18.6 + 4.2x = 3x
subtract 4.2x from both sides of the equation
18.6 = -1.2x

16. y=-5x-20; 17. y=6x+18, or factored y=6(x+3)
Step-by-step explanation:
Your slope is -5
y=-5x+b, solve for b by pluging the point (-3,-5) in for x and y
-5=-5(-3)+b, solve for b
-20=b, now rewrite the equation
y=-5x-20
Your slope is 6
y=-5x+b, solve for b by pluging the point (-3,-0) in for x and y
0=6(-3)+b, solve for b
18=b, now rewrite the equation
y=6x+18, or factored y=6(x+3)

Answer:
[tex]\huge\boxed{y=-2x+5}[/tex]
Step-by-step explanation:
In order to solve for the equation of the line, we need to note a couple of things.
A) If a line is parallel to another, they will both have the same slope B) We can substitute x and y values into the equation to find unknown values.Since the line is parallel to the equation [tex]y = -2x[/tex], we know that the slope is -2.
Equations will be in the form [tex]y = mx+b[/tex], m being the slope, and b being the y-intercept. Since we know the slope, we can substitute it into the equation.
[tex]y = -2x+b[/tex]
Additionally, we know one of the points it passes through. Therefore, we can also substitute this into the equation and find the value of b (y-intercept).
[tex]-3 = -2 \cdot 4 + b[/tex]
Solve for b:
[tex]-3 = -8 + b[/tex] [tex]b = -3+8[/tex] [tex]b = 5[/tex]Now we know the slope and the y-intercept, which is all we need to create our equation.
[tex]y = -2x+5[/tex]

[tex]\int\limits^6_0 {xe^{x} } \, dx = 4e^5 +1[/tex]
Step-by-step explanation:
Step(i):-
Given
[tex]I = \int\limits^6_0 {xe^{x} } \, dx[/tex]
By using UV formula
[tex]\int\limits {UV} \, dx = U\int\limits {v} \, dx - ( \int\limits {(U^{l} } \int\limits {v} \, dx \, )dx[/tex]
Now , we take
U = x and V = e ˣ
U¹ = 1 and [tex]\int\limits {e^{x} } \, dx = e^{x}[/tex]
Step(ii):-
[tex]\int\limits {xe^x} \, dx = x\int\limits {e^x} \, dx - ( \int\limits {(1) } \int\limits {e^x} \, dx \, )dx[/tex]
= x e ˣ - [tex]\int\limits {e^x} \, dx[/tex]
= x e ˣ - e ˣ + C
[tex]\int\limits^6_0 {xe^{x} } \, dx =( e^ x ( x -1) )_{0} ^{6}[/tex]
= e⁵ (5-1) - (e⁰ (0-1)
= 4 e⁵ + 1
Final answer:-
[tex]\int\limits^6_0 {xe^{x} } \, dx = 4e^5 +1[/tex]
