Answer:
(A) y = (x - 2)^2 + 1
Step-by-step explanation:
All the answer choices are in vertex form. Here's the formula for vertex form:
y = a(x - h)^2 + k
h = x coordinate of vertex
k = y coordinate of vertex
We already know that a = 1 because all of the answer choices have a = 1, so to find the right answer, you have to know how to write vertex form when given the vertex.
The vertex is (2, 1). The x coordiante (2) is equal to h, and the y coordinate (1) is equal to k.
Plug these two numbers into the formula and that's your answer!
y = (x - 2)^2 + 1

Answer:
x = [tex]\frac{5}{2}[/tex] , y = [tex]\frac{27}{4}[/tex]
Step-by-step explanation:
Equate the first 2 parts of the ratios on both sides of the equation and solve for x.
Expressing the ratios in fractional form, then
[tex]\frac{x}{3}[/tex] = [tex]\frac{\frac{15}{4} }{\frac{9}{2} }[/tex] = [tex]\frac{15}{4}[/tex] × [tex]\frac{2}{9}[/tex] = [tex]\frac{5}{6}[/tex] ( cross- multiply )
6x = 15 ( divide both sides by 6 )
x = [tex]\frac{15}{6}[/tex] = [tex]\frac{5}{2}[/tex]
-----------------------------------------------------------------------------------
Equate the last 2 parts of the ratios on both sides and solve for y
[tex]\frac{\frac{9}{2} }{y}[/tex] = [tex]\frac{3}{\frac{9}{2} }[/tex] = 3 × [tex]\frac{2}{9}[/tex] = [tex]\frac{2}{3}[/tex] ( cross- multiply )
2y = [tex]\frac{9}{2}[/tex] × 3 = [tex]\frac{27}{2}[/tex] ( divide both sides by 2 )
y = [tex]\frac{27}{4}[/tex]

The admissions officer randomly sampled 50 students from each of these majors who applied to medical school in 2014 and recorded their MCAT score. Here are the three sample standard deviations for the MCAT scores for the three groups (biological sciences majors, social sciences majors, math majors): Column Std. Head Biological Sciences 5.3115216 Social Sciences 6.1661669 Math 4.7821787 Based on this information, do the data meet the condition of equal population standard deviations for the use of the ANOVA? Yes, because 6.17 − 4.78 < 2. Yes, because 6.17/4.78 < 2. No, because the standard deviations are not equal.
Answers
Answer:
Yes, because 6.17/4.78 < 2
Step-by-step explanation:
To test for equal standard deviation ;
Condition is met if the ratio of the large sample standard deviation to the smaer sample standard deviation is less than 2
Sample standard deviation;
Sciences 6.1661669
Math 4.7821787
Biological Sciences 5.3115216
The largest sample standard deviation = 6.1661669
The smallest sample standard deviation = 4.7821787
F statistic = 6.1661669 / 4.7821787 = 1.2894053
F statistic < 2 ; Hence, condition for equal standard deviation is met.

The perimeter of a rectangle is 40 inches. If the width is 9 inches, what is the area of the rectangle?
Answers
Answer:
99 in²
Step-by-step explanation:
Perimeter = 2(length) + 2(width)
40 = 2(length) + 2(9)
40 = 2L + 18
40 - 18 = 2l
22 = 2l
L = 11
Area = length x width
Area = 9 x 11 = 99
99 square inches

Step-by-step explanation:
parallel lines, slope is the same.
two ways to solve it,
y=4x+c
sub y = -11. x =5
-11 = 4(5) + c
c = -31
OR
y-(-11) = 4(x-5)
y+11=4x-20
y=4x-20-11
y=4x-31
Answer:
The equation is y = 4x - 31
Step-by-step explanation:
y - y1 = m (x - x1)
y - (-11) = 4 (x - 5)
y + 11 = 4x - 20
y = 4x - 20 -11
y = 4x - 31

OAmalOHopeO
Answer:
40
Step-by-step explanation:
A tangent to a circle is perpendicular to the radius intersection by definition. That makes BPC a right triangle at B. BP and PD are both equal (9) because every radius of a circle is equal. So
PC**2 = BP**2 + BC**2 or
41**2 = 9**2 + BC**2
1681 = 81 + BC**2
1681 - 81 = BC**2
1600 = BC**2
40 = BC

(the line is a / shape, so the slope is positive)
(the line crosses the y axis at (0,-2)
(using the above information, the equation is y=2x-2)
Answer:
y = 2x - 2
Step-by-step explanation:
Start with
y = mx + b
The graph shows the y-intercept -2.
We have y = mx - 2
slope = m = rise/run
The slope is rise of 2 and run of 1, so m = 2.
y = 2x - 2
An angle measures 89.8° more than the measure of its complementary angle. What is the measure of each angle?
Answers
Complementary angles always are 90 degrees when added to each other, so:
x = angle 1
x + 89.8 = angle 2
x + x + 89.8 = 90
2x = 90 - 89.8
2x = 0.2
x = 0.1
angle 1 = 0.1 degrees
angle 2 = 0.1 + 89.8 = 89.9 degrees
if you want to check, just sum one to the other and see if they equal 90, like this: 89.9 + 0.1 = 90
