Answer:

y = a(x – h)2 + k,

Step-by-step explanation:

Parabolas always have a lowest point (or a highest point, if the parabola is upside-down). This point, where the parabola changes direction, is called the "vertex". If the quadratic is written in the form y = a(x – h)2 + k, then the vertex is the point (h, k). This makes sense, if you think about it.

If there are approximately 1.8 million cars in Vancouver and if each car travels an average of 17,500 kilometres in a year, how

Goryan [66]

Rates are used to measure a quantity over another.

The 1.8 million cars use $1.85 \times 10^{10}$ liters each year

Given

$Cars = 1.8\ million$

$d = 17500km$ --- distance

$r = 40miles/gallon$

First, we calculate the number (n) of gallons used by each car

$r = \frac{d}{n}$

Solve for n

$n = \frac{d}{r}$

So, we have:

$n = \frac{17500km}{40miles/gallon}$

$n = \frac{17500km}{40miles}gallon$

Convert miles to kilometers

$n = \frac{17500km}{40km \times 1.60934}gallon$

$n = \frac{17500km}{64.3738km}gallon$

$n = 271.85\ gallon$

The number of gallons (N), used by all the cars is:

$N = n \times cars$

$N = 271.85 \times 1.8\ million$

$N = 489330000$

Convert to liters

$N = 489330000 \times 3.78541L$

$N = 1852314675.3L$

In scientific notation to 2 decimal places, we have:

$N = 1.85 \times 10^{10}L$

Hence, the number of liters used is $1.85 \times 10^{10}$

What is Mia's error? 83 + n = 110 83 + 83 + n = 110 + 83 n=193

Tanya [424]

Answer:

She added 83 instead of subtracting

Step-by-step explanation:

83 + n = 110

We want to do the opposite to n

We are adding 83 to n. The opposite is subtract 83

83+n-83 = 110-83

n =27

Mia

83 + n = 110

83 + 83 + n = 110 + 83

163+n=193

HELPPPP!!!!! MATH!!!! PLZ!!!!!

MariettaO [177]

Answer:

Y=5x

Step-by-step explanation:

Y=mx+b, or y=rise/run+starting value

as there is no starting value, we would simply add no variable

rise/run in this equation would 5/1 because when it rises 5, it goes right 1, simplifying that would be 5
