Quadrilateral ABCD is similar to quadrilateral EFGH. Find the measure of side EF
Answers
Answer:
EF = 6.6
Step-by-step explanation:
Since ABCD is similar to EFGH, then EH is similar to AD. So, we can solve by first dividing 12 by 2 (EH by AD). The quotient of this is 6. This tells us that quadrilateral EFGH is 6 times larger than quadrilateral ABCD, since they are similar. So, with this and the measurement of AB (which is similar to EF), we can now solve for EF. We simply multiply 1.1 (the measurement of AB) by 6 (how many times larger EFGH is compared to ABCD). The product of this is 6.6, our final answer.

Answers
Answer:
X=-1, y=1
Step-by-step explanation:
Substitute value of y in first equation (3x+4) with y of second equation.
2x-4(3x+4)=-6
2x-12x-16=-6
-10x=10x=-1
solve for y but putting -1 for x value in either equation
y=3(-1)+4

Answers
Answer:
A) ∠BEC is one-half of ∠BAC
B) ∠BEC = 60°
C) ∠BDC = 120°
Step-by-step explanation:
C) arc BDC = 120°
arc BEC = 360° - 120° = 240°
∠BDC = 1/2(240°) = 120°

3x² - 7 = 140
Answers
Answer:
x=7,−7
Step-by-step explanation:
In order to find the value of x in this quadratic equation we first need to make the equation equal 0 by getting rid of the 140. We do this by subtracting 140 on each side.
3x² - 7 = 140
3x² - 147 = 0
Now we solve as a regular quadratic formula
x= [tex]x = \frac{-(0) +- \sqrt{0^{2} - 4(3)(-147) } }{2(3)}[/tex]
[tex]x = \frac{0 +- \sqrt{1764} }{6}[/tex]

The grade seven students are showing a movie in their school auditorium to raise money for the end of year field trip. Goal is to raise at least $500. Each ticket sales for $16. So far they have sold 20 tickets. Which inequality graph correctly shows how many more tickets they need to sell to reach their goal.
Answers
Answer:
The answer is A because it needs to be a filled dot to represent the information correctly. 16 x 20 is 320 so they need 180 more to have at least 500 dollars which is 11.25 tickets but you cant have a fourth of a ticket so you need atleast 12 tickets sold.

Answer:
y = -4/3x +23/2
Step-by-step explanation:
The tangent of interest is perpendicular to the radius at the given point on the circle. To find the perpendicular, it helps to know the slope of the radius segment. To find that, we need the center of the circle.
The center of the circle can be found by completing the square for each variable.
(x^2 -2x) +(y^2 +4y) = 20
(x^2 -2x +1) +(y^2 +4y +4) = 20 +1 +4
(x -1)^2 +(y +2)^2 = 25
Comparing this equation to the standard form equation for a circle, we can find the center.
(x -h)^2 +(y -k)^2 = r^2 . . . . . . . circle of radius r centered at (h, k)
The center of circle P is (1, -2).
__
The slope m' of the line segment between (1, -2) and (5, 1) is given by ...
m' = (y2 -y1)/(x2 -x1)
m' = (1 -(-2))/(5 -1) = 3/4
The slope m of the perpendicular line is the opposite reciprocal of this, so is ...
m = -1/m' = -1/(3/4) = -4/3
The y-intercept of the desired line can be found from ...
b = y -mx . . . . . . . for m=-4/3 and (x, y) = (5, 1)
b = 1 -(-4/3)(5) = 23/3
Then the equation of tangent line AB is ...
y = mx +b
y = -4/3x +23/3
Where are the minimum and maximum values for f(x)=−2+4cosx on the interval [0,2π]?
Answers
Answer:
[tex]f(x) = - 2 + 4 \cos(x) \\ for \: minimum \: \: x = 0 \\ f(0) = - 2 + 4 \cos(0) \\ minimum \: value = 2 \\ for \: maximum \: value \: \: x = 2\pi \\ f(2\pi) = - 2 + 4 \cos(2\pi) \\ maximum \: value = - 2[/tex]
The function is minimum at 3π/2 and the function is maximum at 0 and 2π.
What is the maximum and minimum value of the function?The condition for the maximum will be
f(x)'' < 0
The condition for the minimum will be
f(x)'' > 0
The function is given below.
f(x) = −2 + 4cosx
Differentiate the function with respect to x, then we have
f'(x) = − 4 sin x
Again differentiate the function with respect to x, then we have
f''(x) = − 4 cos x
Then the minimum value of the function will be
f'(x) = 0
−4 sin x = 0
sin x = 0
The value of f''(x) is positive in the interval of (π/2, 3π/2). Then the value of x will be
x = π
Then the maximum value of the function will be
And the of f''(x) is negative in the interval of [0,2π] – (π/2, 3π/2). Then the value of x will be
x = 0 and 2π

Write an equation of the line that passes through the point (-2, 5) and is parallel to the line 2x − 3y = 12.
Answers
Answer:
y = (2/3)x + 19/3
Let me know if there are any parts of the process you do not understand.
Step-by-step explanation:
First you need to know what slope is, if you do not let me know and I can explain it in depth.
Now, you can determine if a line is parallel or perpendicular by its slope. parallel has the same slope and perpendicular has the negative reciporical, which basically means negative 1 divided by the slope.
So if you slope was 3 perpendicular would be -1/3. if the slope is a fraction you can just flip the fraction and make it negative. so if the slope is -2/3 a perpendicular slope would be 3/2, making a negative number negative makes it positive.
Now you start with 2x - 3y = 12. To find the slope I like putting it in slope intercept form. basically somethign that looks liek y = mx + b. to do that just use algebra on what you have to get y by itself. here is how I would do that.
2x - 3y = 12 first subtract 2x from both sides
-3y = 12 - 2x Now divide both sides by -3
y = 12/-3 - (2x)/3 Now simplify
y = -4 + 2/3 x Now rarrange to make it look like I said, basically you want the x first.
y = 2/3 x - 4
There, so the slope is 2/3. A parallel line will have the same slope.
To make the equation of a line you want one point and the slope. Well we have that, the point is (-2,5) and the slope is 2/3.
To find a line you set up the point slope form. that is y - y1 = m(x - x1) where m is the slope and x1 and y1 are the coordinates of the point you need. I will plug all that in.
y - y1 = m(x - x1)
y - 5 = (2/3)(x - (-2)) Now solve
y - 5 = (2/3)x + 4/3
y = (2/3)x + 19/3
So that is the equation of a line parallel to 2x - 3y = 12 that passes through (-2, 5)

ASAPPP! An arrow is shot into the air. A function representing the relationship between the number of
seconds it is in the air, t, and the height of the arrow in feet, h, is given by the equation below.
What is the initial height of the arrow?
h(t) = -16t^2+ 128t + 1.5
Answers
Answer:
The initial height of the arrow is 1.5 feet above the ground.
Step-by-step explanation:
Let be the height of the arrow be represented by the function [tex]h(t) = -16\cdot t^{2}+128\cdot t + 1.5[/tex], where [tex]h(t)[/tex] is the current height of the arrow, measured in feet, and [tex]t[/tex], is the time, measured in seconds.
Mathematically speaking, the initial height is the value of [tex]h[/tex] evaluated at [tex]t = 0\,s[/tex]. That is:
[tex]h(0) = -16\cdot (0)^{2}+128\cdot (0) + 1.5[/tex]
[tex]h(0) = 1.5\,ft[/tex]
The initial height of the arrow is 1.5 feet above the ground.
