We have the expressions:




Now, with this we operate as follows:
a)


Then, the axis is x = -3 and the vertex (-3, 6)
b)


Then, the vertex is (2, 5) and the axis is x = 2.
c)

Then, the vertex is (2, -4) andd the axis is x = 2.
d)


Then, the vertex is (-7/2, -57/4) and the axis is -7/2.
Answer:
$235.2
Step-by-step explanation:
Given data
Principal= $5,600
Rate= 4.2%
Time= 1 year
The expression for the simple interest is given as
SI= PRT/100
substitute
SI= 5600*4.2*1/100
SI= 23520/100
SI=$235.2
Hence after 1 year he will pay $235.2
Let c represent the original amount that this guy had saved up.
He spent 25% of this amount, or 0.25c, on the printer.
To progress further, we have to know how much the printer cost.
Supposing that the printer cost $100 (which we do not know as a fact), this would be equal to 0.25c.
Thus, his savings originally amounted to c = $100/0.25 = $400.
12/72 is equivalent to 1/6
1/6 of the population are building a nest
1/6 of 10,800 is 10,800/6 which is 1,800
about 1,800 are building a nest
First divide the numerator ( 10 ) by the denominator ( 15 ) to get around .666666667, now that is in decimal form, time convert to percentage multiply by 100 to get around 66.66666667 percent. Now round up to the nearest tenth to get 66.7 percent.
We rounded up since 6 in the hundredths place is greater than it equal to 5.
