A
Step-by-step explanation:
The equation of a parabola in vertex form is
y = a(x - h)² + k
(h, k) are the coordinates of the vertex and a is a multiplier
Given
f(x) = - 2x² - 12x - 16
To complete the square the coefficient of the x² term must be 1
Factor out - 2 from - 2x² - 12x
f(x) = - 2(x² + 6x) - 16
add/ subtract ( half the coefficient of the x- term )² to x² + 6x
f(x) = - 2(x² + 2(3)x + 9 - 9 ) - 16
= - 2(x + 3)² + 18 - 16
= - 2(x + 3)² + 2 ; y = 2

find the value of x and show how

Answer:
x≈ 5.4
Step-by-step explanation:
180°-110°= 70°
70° is the measure of the angle represented by 11x+11
set the equation equal to 70°
11x+11= 70°
-11 on both sides
11x= 59
÷11 on both sides
x≈ 5.4
11(5.4)+11≈ 70.4 ≈70

Jesse measured his height to be 67 inches. His actual height is 68.5 inches. What is the percent error for Jesse's measurem
Answers
Answer:
2.24%
Step-by-step explanation:
Given that :
Actual height = 68.5
Measured height = 67
Percentage error :
(Error value / True value) * 100%
Error = Actual - observed = (68.5 - 67) = 1.5
Percentage error :
(1.5 / 67) * 100%
0.0223880 * 100%
= 2.2388%
= 2.24%
What is the value of the smaller zero of the function defined by 2x2 + 9x + 7?
Answers
Answer:
We can factor the quadratic function into (2x + 7)(x + 1) and this way, the terms sum to 2x^2 + 9x + 7. Looking at the 2 factors 2x+7 and x+1, the way to find the zeros is to set both of these expressions equal to 0. Therefore we have: 2x+7=0

so 30.599 ≈ 30.60
Answer:
30.6
Step-by-step explanation:
the hundredth in 30.599 is the bold since 9 is greater than 9 you will regroup 1 to the tenths place to get 30.6
The shapes of the horizontal cross-sections of the cone below are not all
congruent.
A. True
B. False
Answers
Answer:
B. False
Step-by-step explanation:
We are given the statement,
'The shapes of the horizontal cross-sections of the cone are all congruent'.
Now, if we cut the cone horizontally, the cross-sectional shape is a 'circle'.
Further, the radius of the circle vary depending on the position form where the cone is cut i.e.
If cut from the top, the circle is approximately equal to a point.
If cut from the middle, the radius of the circle is less than the radius of the cone.
If cut from the bottom, the radius of the circle is equal to the radius of the cone.
Now, 'two figures are congruent if they overlap each other'.
Since, the circles have different radius, they will not overlap each other.
Thus, all the cross-sections of the cone would not be congruent.
Hence, the given statement is false.
Step-by-step explanation:
The solution is, the given statement is B. False.
What is a cross-section of any shape?A cross-section is a shape formed by cutting a solid (such as a cone, cylinder, or sphere) with a plane. If a cylinder-shaped object is cut by a plane parallel to its base, the resulting cross-section is a circle. As a result, the object intersected.
here, we have,
We are given the statement,
'The shapes of the horizontal cross-sections of the cone are all congruent'.
Now, if we cut the cone horizontally, the cross-sectional shape is a 'circle'.
Further, the radius of the circle vary depending on the position form where the cone is cut i.e.
If cut from the top, the circle is approximately equal to a point.
If cut from the middle, the radius of the circle is less than the radius of the cone.
If cut from the bottom, the radius of the circle is equal to the radius of the cone.
Now, 'two figures are congruent if they overlap each other'.
Since, the circles have different radius, they will not overlap each other.
Thus, all the cross-sections of the cone would not be congruent.

A cyclist travels at an average speed of 20 km/h over a distance of 40 km.
How many hours does it take him?
Answers
Answer:
Given that speed(v) = 20km/h and time(t) = 50 min
We have to find distance (d)
First convert speed into m/s
v = (20*1000m)/(1*3600s)
v = (50/9) m/s
Now convert time into second
t = 50*60 = 3000 sec
As we know that
d = v*t = (50/9)*3000 = 50000/3
d = 16666.67m or 16.67km
Ans: 16666.67m or 16.67km
