Answer:
Step-by-step explanation:
g(4)=4²/4+7=11
g(-2)=(-2)²/4+7=4/4+7=1+7=8
average rate of change over the interval [-2,4]=(g(4)-g(-2))/4-(-2))
=(11-8)/6
=3/6
=1/2
Answer:
-1/2
Step-by-step explanation:
To find the average rate of change (ARC) of the function g over the interval [-2,4] we need to take the total change in the function value over the interval (which is the difference of its values at the endpoints) and divide it by the length of the interval:
ARC [−2,4] =g(4)-g(-2)/4-(-2)
Note that this is the same as finding the slope of the line connecting the points on the graph that correspond to the endpoints of the interval:
What is 12.357 in expanded form
Answer:
10+2+0.3+0.05+0.007
Step-by-step explanation:
The number 12.357 in expanded form is written as 1 x 10 + 2 x 1 + 3 x 0.1 + 5 x 0.01 + 7 x 0.001. This represents the actual value of each digit in the number depending on its position.
Explanation:The number 12.357 in expanded form is written as:
1 x 10 + 2 x 1 + 3 x 0.1 + 5 x 0.01 + 7 x 0.001.
Expanded form is a way of breaking down a number into its individual place value components. The correct intention is to show each digit's actual value, considering its position within the number. In this case, '1' is in the 'tens' place, '2' in the 'ones', '3' in the tenths', '5' in the 'hundredths' and '7' in the 'thousandths' place.

Which two ratios form a proportion?
02:3 and 4:12
2:3 and 6:12
2:3 and 12:18
2:3 and 12:36
2: 3 and 12: 18 form a proportion
Step-by-step explanation:
When the two ratios are equal then they are said to be in proportion.
[tex]$\frac{2}{3}[/tex] ≠ [tex]$\frac{4}{12} = \frac{1}{3}[/tex]
So 2:3 and 4:12 are not in proportion.
[tex]$\frac{2}{3}[/tex] ≠ [tex]$\frac{6}{12} = \frac{1}{2}[/tex]
So 2:3 and 6:12 are not in proportion
[tex]$\frac{2}{3}[/tex] ≠ [tex]$\frac{12}{18} = \frac{2}{3}[/tex]
So 2:3 and 12:18 are in proportion
[tex]$\frac{2}{3}[/tex] ≠ [tex]$\frac{12}{36} = \frac{1}{3}[/tex]
So 2:3 and 12: 36 are not in proportion

Step-by-step explanation:
MN is a midline segment and is half the length of GH, thus
GH = 2 × MN, substitute values

A. An object with a positive charge will be attracted to the positive plate.
B. An object with a negative charge will remain stationary between the plates.
C. An object with a negative charge will be attracted to the negative plate.
D. An object with a positive charge will move toward the negative plate.

Maya is working two summer jobs, making $7 per hour babysitting and $11 per hour landscaping. Last week Maya earned a total of $96 and worked 3 times as many hours babysitting as she worked hours landscaping. Determine the number of hours Maya worked babysitting last week and the number of hours she worked landscaping last week.
The number of hours Maya worked babysitting and landscaping last week is 2.4 hours and 7.2 hours respectively
Given:
Earnings for babysitting = $7
my Earnings for landscaping = $11
Total earnings = $96
Iet
number of hours babysitting = x
number of hours landscaping = y
y = 3 × x
y = 3x (1)
y = 3x (1)7x + 11y = 96 (2)
substitute (1) into (2)
7x + 11y = 96 (2)
7x + 11(3x) = 96
7x + 33x = 96
40x = 96
x = 96/40
x = 2.4 hours
substitute x = 2.4 into (1)
y = 3x (1)
y = 3(2.4)
y = 7.2 hours
Therefore, the number of hours Maya worked babysitting and landscaping last week is 2.4 hours and 7.2 hours respectively

A sphere with a radius of 3 cm has the same volume as a cone with a radius of 6 cm. What is the height of the cone?!
2 cm
3 cm
4 cm
5 cm
Answer:
Step-by-step explanation:
VC = (1/3)·pi·r2·h
VC = volume of a cone
r = radius of base of cone = 6 cm
h = height
VC = (1/3)·pi·62·h
VC = 12·pi·h
VS = (4/3)·pi·r3
VS = volume of a sphere
r = radius of base of sphere = 3 cm
VS = (4/3)·pi·33
VS = 36·pi
Since the volume of the cone and the sphere are equal:
VC = VS
12·pi·h = 36·pi
Solve for h.
Describe what an "included" angle is. Give an example.
Answer:
The angle between two sides is the included angle.
Example:
In triangle ABC,
Angle B is an included angles because it's formed by two sides AB and CB which meet at point B.
Similarly, other angles in a triangle are also included.
This is for all segments which meet at point, triangle is just one example
What's the value of x? 40000mg =10x g
The value of x is 4. So 40000 mg= 40 g.
Step-by-step explanation:
The given is 40000mg = 10x g
Step:1
Take given equation as equation (1)
40000 mg= 10x g.................(1)
where, X is known value.
Step:2
Standard value for mg to g for the purpose of conversion of units,
1 milligram = 0.001 gram (or)
1 gram = 1000 milligram
Step:3
From the standard data values,
= 40000 mg
it converted mg to g by dividing 1000
= [tex]\frac{40000}{1000}[/tex] g
= 40 g.......................(2)
Step:4
From the Equations (1) and (2),
40=10x
x=4
Result:
The value of x is 4. So, 40000mg = 40 g.

Which equation can be used to solve for angle N in the triangle below?
A. 6.2^2 = 3.6^2 + 4.3^2 - 2(3.6)(4.3)cosN
B. 6.2^2 = 3.6^2 + 4.3^2 + 2(3.6)(4.3)cosN
C. 6.2^2 = 3.6^2 + 4.3^2 - (3.6)(4.3)cosN
D. 6.2^2 = 3.6^2 + 4.3^2 + (3.6)(4.3)cosN
Option A:
The equation used to solve for angle N is
[tex]6.2^{2}=3.6^{2}+4.3^{2}-2(3.6)(4.3) \cdot \cos N[/tex]
Solution:
Given data:
MO = 6.2 cm
ON = 4.3 cm
MN = 3.6 cm
To find the equation to solve for angle N:
Using cosine formula,
[tex]c^{2}=a^{2}+b^{2}-2 a b \cdot \cos C[/tex]
Here, a = 3.6 cm, b = 4.3 cm, c = 6.2 cm, and angle A = angle C
Substitute these in the formula, we get
[tex]6.2^{2}=3.6^{2}+4.3^{2}-2(3.6)(4.3) \cdot \cos N[/tex]
The equation used to solve for angle N is
[tex]6.2^{2}=3.6^{2}+4.3^{2}-2(3.6)(4.3) \cdot \cos N[/tex]
Hence option A is the correct answer.

(6x – 10)
x=
Answer:
First of all (3x + 50) is equal to (6x - 10) so (3x + 50) = (6x - 10) 3x + 50 = 6x - 10 60 = 3x 20 = x
Step-by-step explanation:
Answer:
Step-by-step explanation:
(3x + 50)(6x + -10) = 0
Reorder the terms:
(50 + 3x)(6x + -10) = 0
Reorder the terms:
(50 + 3x)(-10 + 6x) = 0
Multiply (50 + 3x) * (-10 + 6x)
(50(-10 + 6x) + 3x * (-10 + 6x)) = 0
((-10 * 50 + 6x * 50) + 3x * (-10 + 6x)) = 0
((-500 + 300x) + 3x * (-10 + 6x)) = 0
(-500 + 300x + (-10 * 3x + 6x * 3x)) = 0
(-500 + 300x + (-30x + 18x2)) = 0
Combine like terms: 300x + -30x = 270x
(-500 + 270x + 18x2) = 0
Solving
-500 + 270x + 18x2 = 0
Solving for variable 'x'.
Factor out the Greatest Common Factor (GCF), '2'.
2(-250 + 135x + 9x2) = 0
Factor a trinomial.
2((-50 + -3x)(5 + -3x)) = 0
