Answer:
4x + 4 <em>or</em> (2x) + (2x+4)
Step-by-step explanation:
Ok so east is the right side. The length of the east side would be (2x) + (2x+4). You can then simplify this to 4x + 4 but I don't know if your teacher wants you to do that. Hope this helps!
<u>Answer</u>:
3y = 4(x - 1.5)²
<u>Step-by-step explanation:</u>
The equation of the parabola in the vertex form is:
y = a (x-h)² + k
Where: (h,k) the coordinates of the vertex & a is a multiplier
The parabola has a vertex at ( 1.5 , 0 )
So, h = 1.5 , k = 0
∴ y = a (x - 1.5)² + 0
∴ y = a (x - 1.5)²
The parabola passes through points ( 3 , 3 )
∴ 3 = a (3 - 1.5)²
∴ 1.5² a = 3 ⇒ a = 3/1.5² = 3/2.25 = 4/3
∴ y = (4/3) (x - 1.5)²
mukitbly both sides by 3
∴ 3y = 4(x - 1.5)²
So, the equation of a parabola that has a vertex at ( 1.5 , 0 ) and passes through points ( 3 , 3 ) is 3y = 4(x - 1.5)²
See the attached figure.
A main characteristic of a function is that each output has exactly one input. This means that for the X value there can’t be any repeats, making the answer C.
Answer:
Population = 75,342 households
Sample = 400 randomly selected households
The percentage who live in a single household unit = Parameter
The average of 2.9 person per household of all households in the city = parameter
The $65,000 median family income of all the households in the city = Parameter
Step-by-step explanation:
The population refers to all the entire elements, observations or subject which fits into a particular study. In the scenario above, the entire household in the city of study. That is, the 75,342 households.
The sample is the subset of the population which is a smaller set of observation meant to be representative of the larger population. The sample here is the 400 randomly selected households.
Parameter differs from statistics in that numerical estimates or calculations obtained from the population is called the parameter while the numerical characteristics derived from the sample is called statistic.
Answer:
The equation is x= (7.74 /9) 6
Step-by-step explanation:
Hi, to answer this question we have to analyze the information given:
If 9 pencils cost $7.74, we have to divide the total cost ($7.74) by the number of pencils (9) to obtain the price of 1 pencil.
Now that we have the price of 1 pencil, to obtain the cost of 6 of them we simply multiply the result by six.
Mathematically speaking:
x= (7.74 /9) 6
Where:
x = Cost of 6 pencils in $
Solving:
x = 0.86 x 6 = $5.16
