Y=x^2 translate 4 units down and 3 units left

1 answer:

3 0

Answer: Hello! When a graph is translated 4 units down you are moving all of the y values. This makes it the easiest translation that we do, other than no translation! All you have to do is subtract 4. Your equation is y=x2 - 4. If you wanted to move the graph up it is addition and if you want to move it down it is subtraction. When you translate right to left it is more complicated! Hope this helps. :))

So, you had done everything right so far (other than squaring the 2), but that was only half of the question.

to find the least common multiple, you need to first figure out what the prime factors have in common.
${2}^{2} \times 3 \times 5 \\ and \\ {2}^{2} \times {3}^{2} \times 5 \times 7$
each have two twos. both have one 5, so we know our answer will look something like
${2}^{2} \times 5 \times other \: stuff$
now to figure out the other stuff... we have to represent the greatest amount of everything that is left, and we have 3s and 7s left over, so we need to figure out how many of each we need.

one has one 3 and one has two, so we need two threes. now our equation is
${2}^{2} \times {3}^{2} \times 5 \times stuff$

what's the only number we have to deal with? 7...

how many sevens does 60 have? 0, and 630 has 1, so we know we need one 7. our answer becomes

What is the area of the rectangle shown on the coordinate plane? Enter your answer in the box. Do not round at any steps. units²

Goshia [24]

<h3>Answer: 42 square units</h3>

Check out the attached images below. In figure 1, I plotted the four points given as A, B, C, D; then connected them to form a rectangle.

Figure 2 shows 4 more points E, F, G, H made so that a larger rectangle forms. This newer larger rectangle entirely encloses the first rectangle. The idea is to find the area of the larger rectangle, and subtract off the areas of the four triangular pieces shown in figure 3. These images are attached below.

area of rectangle EFGH = base*height = 10*10 = 100

area of triangle ABE = base*height/2 = 3*3/2 = 4.5

area of triangle ADH = base*height/2 = 7*7/2 = 24.5

area of triangle CGD = base*height/2 = 3*3/2 = 4.5

area of triangle FCB = base*height/2 = 7*7/2 = 24.5

the four triangles have areas that add up to 4.5+24.5+4.5+24.5 = 58

Subtract this from the area of rectangle EFGH to get 100-58 = 42

----------

alternatively, you can find the distance from A to B getting roughly 4.24264 (use the distance formula). The distance from B to C is roughly 9.89949

Multiply those two values: 4.24264 * 9.89949 = 41.9999722536 which rounds to 42. There's rounding error based on the fact that the previously mentioned decimal values are approximate.

Which expression can be used to convert 80 US dollars (USD) to Australian dollars (AUD)? 1 USD = 1.0343 AUD 1 AUD = 0.9668 USD

kakasveta [241]

The answer is 1 USD = 1.0343 AUD
because the ratio is 1 USD:1.0343 AUD
fraction is
1.0343AUD/1USD

use to cancel out units
1.0343AUD/1USD times 80 USD=82.744 AUD
