PLEASE HELP - 60 POINTS
m<1=m<2 = 38°
m<3= m<4= 142°
Answer:
Angles 1 and 2 are vertically opposite and angles 3 and 4 are vertically opposite and as such the are congruent.
m∠3 = 142° ⇒ m∠4 = m∠3 = 142°Angles 1 and 3 are supplementary and angles 2 and 4 are supplementary and as such sum to 180°.

Step-by-step explanation:
So, at from x 0 to x 2, y goes up 4
Answer:
2
Step-by-step explanation:
The rate of change is defined by [tex]\frac{Rise}{Run}[/tex] , [tex]\frac{y_{2} - y_{1} }{x_{2}-x_{1}}[/tex]. or [tex]\frac{Delta y}{Delta x}[/tex].
For your question, the points are (0,4) and (2,8).
Plugging these points into the formula:
[tex]\frac{8-4}{2-8}[/tex]
After calculations, you would end up with [tex]\frac{4}{2}[/tex] or 2.
A quarter back completes 23% of his passes. We want to observe this quarterback during one game to see how many pass attempts he makes before completing one pass. What is the probability that the quarterback throws exactly 6 incomplete passes before he has a completion
Answer:
[tex]Pr = 0.0479[/tex]
Step-by-step explanation:
Given
[tex]p =23\%[/tex] --- proportion of completed passes
Required
The probability that he has 6 incomplete before he has 1 completion
Let:
[tex]q \to[/tex] proportion of back passes not completed
Using complement rule:
[tex]q = 1 - p[/tex]
[tex]q = 1 - 23\%[/tex]
[tex]q = 1 - 0.23[/tex]
[tex]q = 0.77[/tex]
The event that he has 6 incomplete passes before he completed one is:
q q q q q q p
And the probability is:
[tex]Pr = q * q * q * q * q * q * p[/tex]
[tex]Pr = q^6* p[/tex]
[tex]Pr = 0.77^6* 0.23[/tex]
[tex]Pr = 0.0479[/tex]

Find an equation of the circle whose diameter has endpoints (6,4) and (2,-6)
Answer:
[tex](x-4)^2+(y+1)^2=29[/tex]
Step-by-step explanation:
We want to find a circle whose diameter has the endpoints (6, 4) and (2, -6).
Since this is the diameter, its midpoint will be the center of the circle. Find the midpoint:
[tex]\displaystyle M=\left(\frac{6+2}{2}, \frac{4+(-6)}2}\right)=(4, -1)[/tex]
So, the center of our circle is (4, -1).
Next, to find the radius, we can find the length of the diameter and divide it by half.
Using the distance formula, find the length of the diameter:
[tex]\begin{aligned} d&=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}\\\\ &=\sqrt{(2-6)^2+(-6-4)^2}\\\\&=\sqrt{(4)^2+(-10)^2}\\\\&=\sqrt{116}\\\\&=2\sqrt{29}\end{aligned}[/tex]
So, the radius will be:
[tex]\displaystyle r=\frac{1}{2}d=\frac{1}{2}\left(2\sqrt{29}\right)=\sqrt{29}[/tex]
The equation for a circle is given by:
[tex]\displaystyle (x-h)^2+(y-k)^2=r^2[/tex]
Substitute:
[tex](x-4)^2+(y+1)^2=29[/tex]

Given right triangle ABC, what is the value of tan(A)?
The value of angle tanA in a right-angle triangle is 12/5. The correct option is C.
What is trigonometry?The branch of mathematics that sets up a relationship between the sides and the angles of the right-angle triangle is termed trigonometry.
The trigonometric functions, also known as a circular, angle, or goniometric functions in mathematics, are real functions that link the angle of a right-angled triangle to the ratios of its two side lengths.
Given that the three sides of the right-angled triangle are AB = 26, BC = 24, and AC = 10.
The value of angle tanA will be calculated as:-
tanA = P / B
tanA = 24 / 10
tanA = 12 / 5
Hence, the value of angle tanA in a right-angle triangle is 12/5. The correct option is C.

mother's age is 3 times my age 3y
brother is 2 years younger than me y - 2
father's age is 4 times my brother's age 4(y - 2)

total of our four ages is 116 years.
a) Write an equation to show this.
y + 3y + (y - 2) + 4(y - 2) = 116
b) Solve the equation.
distribute
y + 3y + y - 2 + 4y - 8 = 116
combine like terms
9y - 10 = 116
add 10 to both sides
9y = 126
Divide both sides by 9

A rectangular dog pen is constructed using a barn wall as one side and 64 m of fencing for the other three sides what is the maximum area of the dog pen
Answer:
The answer is below
Step-by-step explanation:
Let x represent the length of the rectangular pen and y represent the width of the rectangular pen.
One side of the pen uses the barn wall, hence the remaining side is 64 m, hence:
x + 2y = 64
x = 64 - 2y (1)
The area of the wall is the product of the length and the width, hence:
Area (A) = length * width = xy = (64 - 2y)y = 64y - 2y²
A = 64y - 2y²
The maximum area of the dog house is gotten when the derivative of the area is equal to 0. Hence:
A' = 64 - 4y = 0
64 - 4y = 0
4y = 64
y = 16 m
Put y = 16, in equation 1 to find x:
x = 64 - 2(16) = 32 m
x = 32 m
Therefore the pen has a length of 32 m and width of 16 m.
Answer:
A(max) = 512 m²
Dimensions:
x = 32 m
y = 16 m
Step-by-step explanation:
Area of the rectangular pen:
A(p) = x*y x and y sides of the rectangle. A barn will be used in place of a fence; let´s say that only one x side will be fenced, then the perimeter of the rectangle is:
p = x + 2*y 64 = x * 2*y y = ( 64 - x ) / 2
A(p) = x*y
Area as a function of x
A(x) = x * ( 64 - x )/ 2
A(x) = ( 64*x - x² ) /2
Tacking derivatives on both sides of the equation
A´(x) = ( 64 -2*x )/2
A´(x) = 0 64 - 2*x = 0 2*x = 64 x = 32 m
y = ( 64 - x ) / 2 y = ( 64 - 32 )/2 y = 16 m
A(max) = 32 * 16 = 512 m²
To check if x = 32 will bring a maximum to function A(x)
We take the second derivative
A´´(x) = - x/4 A´´(x) < 0 then x = 32 is a local maximum

What is the solution to the system of equations?
Answer:
x=4, y=-2
Step-by-step explanation:
Answer:
x = 4
y = - 2
Step-by-step explanation:
3x + 8y = - 4
2x - 4y = 16 Multiply the second equation by 2 and add it to the 1st
3x + 8y = - 4
4x - 8y = 32 Add
7x = 28 Divide by 7
7x/7 = 28/7
x = 4
2x - 4y = 16 Substitute 4 for x
2*4 - 4y = 16 Combine
8 - 4y = 16 Subtract 8 from both sides
-4y = 16 - 8
-4y = 8 Divide by -4
y = 8/-4
y = - 2
