One interior angle of a triangle is 60'. The other angle measures are x' and y'. Which of the following could be the values of x
and y? Select all that apply.
A x = 50, y = 90
B. * = 100, y = 20
C. x = 45, y = 45
D. X = 40, y = 80
E. x = 60, y = 60
Answer:
B. x = 100, y = 20
D. X = 40, y = 80
E. x = 60, y = 60
Step-by-step explanation:
The sum of interior angles of a triangle = 180°
From the above question, one of the angles = 60°
The value for the two other interior angles = 180° - 60° = 120°
Hence, the following options could be the values of x and y is given as x + y = 120
Therefore,
B. x = 100, y = 20
D. X = 40, y = 80
E. x = 60, y = 60

⦁ Convert the vertex form of the equation you wrote above to standard form.
the vertex was ax+b(?)
Answer:
ax^2 + bx + c
Step-by-step explanation:
im pretty sure this answers your question
The standard form of the vertex form equation is y = 2x² - 12x + 17
How to convert the equation?The vertex form of a quadratic equation is represented as:
y = a(x - h)² + k
Using the above form, the quadratic equation can be represented as:
y = 2(x - 3)² + 1
Expand
y = 2(x² - 6x + 9) - 1
Further expand
y = 2x² - 12x + 18 - 1
Evaluate the like terms
y = 2x² - 12x + 17
Hence, the standard form of the vertex form equation is y = 2x² - 12x + 17

Write an equation of the line, in point-slope form, that passes through the points (–7, 2) and (3, –2). Use (–7, 2) as the point (x1, y1)
Answer:
first use the equation m = y2 - y1 / x2- x1 to get the slope
m = -2 - 2 = -4
m = 3 + 7 = 10 when there is a negative for x1 it turns positive
the slope is -4/10 or -2/5
now plus the info into the point slope equation
y - y1 = m (x-x1)
this is in point slope form y - 2 = -2/5 (x + 7)
This is how to get it in y-intercept form
y -2 = -2/5x + -2.8
now add -2 on both sides to the -2.8
y = -2/5x (Slope) + -0.8 y- intercept

If CosA= sqrt 3/2, what is TanA?
Answer:
√(3)/3
Step-by-step explanation:
cos(A) = adj./hyp.
adj. = √(3) or √(3)/2
hyp. = 2 or 1
use unit circle:
hyp. = 1
adj. = √(3)/2
use pythagorean theorem c² - b² = a²
1² - (√(3)/2)² = 1 - 0.75 = 0.25
a² = 0.25
a = √(0.25)
a = 0.5
tan(A) = opp./adj.
tan(A) = 0.5/(√(3)/2)
tan(A) = 1/√(3)
rationalize
tan(A) = √(3)/3

Answer:
I'll do the dilation for the first point and you will see the answer (please verify the second point)
Step-by-step explanation:
The dilation about the origin is straightforward, you just multiply the coordinates of each point by the scale factor.
so the dilated point for (-4,-4) is -4x3.5= -14 which is the same for the y coordinate.
so the dilated point for (-4,-4) is (-14, -14)
Please verify by computing the dilated point for (-6,4)

Answer:
Step-by-step explanation:
Given :
Using cosine rule :
c² = a² + b² - 2abCosC
c² = 45² + 25² - 2(45)(25) - cos70
c² = 2650 - 2250 * - 0.3420201
c² = 2650 + 769.54532
c² = 3419.5453
c = sqrt(3419.5453)
c = 58.476
c = 58.5 feets

A parabola can be drawn given a focus of (4, -8) and a directrix of y=-6
. What can be said about the parabola?
Answer:
y = 1/4 (x-4)² - 7
Step-by-step explanation:
Point (x , y) on the parabola, focus of (4, -8) and a directrix of y= -6
√(x-4)²+(y- -8)² = √(y- -6)²
(x-4)² + (y+8)² = (y+6)²
(y+8)² - (y+6)² = (x-4)²
(y²+16y+64) - (y²+12y+36) = (x-4)²
y²+16y+64-y²-12y-36 = 4y+28 = (x-4)²
4y = (x-4)² - 28
y = 1/4 (x-4)² - 7
standard formula of parabola: y = a(x-h)² + k (h,k): vertex (4,-7)
The value of equation of parabola is,
⇒ y = 1/4 (x-4)² - 7
What is Parabola?A parabola is a U-shaped plane curve where any point is at an equal distance from a fixed point (known as the focus) and from a fixed straight line, which is known as the directrix.
Now,
Let a point (x , y) on the parabola, focus of (4, -8) and a directrix of y= -6
Hence, We can formulate;
⇒ √(x-4)²+(y- (-8))² = √(y- (-6))²
⇒ (x-4)² + (y+8)² = (y+6)²
⇒ (y+8)² - (y+6)² = (x-4)²
⇒ (y²+16y+64) - (y²+12y+36) = (x-4)²
⇒ y²+16y+64-y²-12y-36 = 4y+28 = (x-4)²
⇒ 4y = (x-4)² - 28
⇒ y = 1/4 (x-4)² - 7
Thus, The value of equation of parabola is,
⇒ y = 1/4 (x-4)² - 7

Given the first term and the common ratio of a geometric sequence find the seventh term of the sequence. a1=2 and r=6
Answer:
93312
Step-by-step explanation:
We can use the geometric sequence formula
a= a1(r)^n-1
Substitute:
a=2(6)n^1
a=2 *6^n* 1/6
a=6^n*1/3
Substitute "7" for n:
a(7)=6^(7)*1/3
a(7)=93,312
I need help with question 18. The answer is53√3 ft^2. But how do I get there?
Answer:
Hope it helps....
Step-by-step explanation:
Answer:
52√3 ft²
Step-by-step explanation:
sin 60° = (√3) / 2 = h/8
h = 8 x (√3) / 2 = 4√3
cos 60° = 1/2 = a/8
a = 4 b = 15-4 = 11
area = left triangle + right rectangle
area = (4*4√3) / 2 + 11*4√3
= 8√3 + 44√3
= 52√3

Answer:
A. (-4, -4)
Step-by-step explanation:
According to the word problem, a dilation of (0.75x, 0.75y) is applied to a triangle.
This means the original coordinates were enlarged/multiplied by 0.75.
We can multiply the coordinates at the bottom by 0.75 to see if we get any of the resulting images' coordinates.
OR
We could divide the resulting images' coordinates by 0.75 to see if we get any of the answers on the bottom.
For instance,
(-3, -3)
-3 / 0.75 = -4 (x-coordinate)
-3 / 0.75 = -4 (y-coordinate)
This means (-4, -4) were the original coordinates of (-3, -3) before the dilation of 0.75.

Ok my question says "destiny and carla had a total of 3 gallons of paint to share for a project they had 1 gallon each yellow blue and red paint destiny used 3/8 gallon of yellow paint 1/2 of blue paint 1/4 of red paint carla used 1/4 of yellow 3/8 of blue and 1/4 of red then part a ask how much more paint in gallons did destiny use than carly
Answer: 1/4
Step-by-step explanation:
Since Destiny used 3/8 gallon of yellow paint, 1/2 of blue paint and 1/4 of red paint, the total paint used will be:
= ⅜ + ½ + ¼
= 3/8 + 4/8 + 2/8
= 9/8
= 1 1/8
Carla used 1/4 of yellow, 3/8 of blue and 1/4 of red. The total paint used will be:
= 1/4 + 3/8 + 1/4
= 2/8 + 3/8 + 2/8
= 7/8
The numybe of paint that Destiny use more than Carla will be:
= 1 1/8 - 7/8
= 2/8
= 1/4
Destiny used 1/4 paint more than Carla
