Answer:

y + 6 = (x -3)^2

Step-by-step explanation:

Let's use the general form of the vertex equation of a quadratic:  y - k = a(x - h)^2.

Subst. 10 for y, 7 for x, -6 for k and 3 for h.  Then, 10 + 6 = a(7 - 3)^2, or

16 = a(4)^2, or 16 = a(16).  Thus, a = 1, and the equation of this particular parabola is:

y + 6 = (x -3)^2

Is 60o grams equal to 6 kilograms
Leno4ka [110]

Answer: No, they are not equal

1 kilogram = 1000 grams

6 kilograms = 6*1000 = 6000 grams

so we see that 6 kilograms is larger than 600 grams

Put another way,

600 grams = 600/1000 = 0.6 kilograms

17. The length of a rectangle is 3 inches greater than its width. The perimeter is 28 inches.
Anna11 [10]

Answer:

\boxed{ \bold{ \sf{ width \: of \: a \: rectangle = 5.5 \: inches}}}

\boxed{ \bold{ \sf{length \: of \: a \: rectangle =8.5 \ \: \:  inches}}}

Step-by-step explanation:

Let the width of a rectangle be 'w'

Length of a rectangle = w + 3

Perimeter of a rectangle = 28 inches

To find : dimensions of the rectangle ( length and width )

<u>Finding </u><u>the</u><u> </u><u>width</u><u> </u><u>of</u><u> </u><u>a</u><u> </u><u>rectangle</u><u> </u><u>(</u><u> </u><u>w</u><u> </u><u>)</u><u> </u>

\boxed{ \sf{perimeter \: of \: a \: rectangle = 2(l + w)}}

\dashrightarrow{ \sf{28 = 2(w + 3 + w)}}

\dashrightarrow{ \sf{28 = 2(2w + 3)}}

\dashrightarrow{ \sf{28 = 4w + 6}}

\dashrightarrow{ \sf{4w + 6 = 28}}

\dashrightarrow{ \sf{4w = 28 - 6}}

\dashrightarrow{ \sf{4w = 22}}

\dashrightarrow{ \sf{ \frac{4w}{4}  =  \frac{22}{4} }}

\dashrightarrow{ \sf{w = 5.5 \: inches}}

Width of a rectangle = 5.5 inches

<u>Now</u><u>,</u><u> </u><u>replacing</u><u> </u><u>/</u><u> </u><u>substit</u><u>uting</u><u> </u><u>the</u><u> </u><u>value</u><u> </u><u>of</u><u> </u><u>w</u><u> </u><u>in</u><u> </u><u>order</u><u> </u><u>to</u><u> </u><u>find</u><u> </u><u>the </u><u>length</u><u> </u><u>of</u><u> </u><u>a</u><u> </u><u>rectangle</u><u> </u>

\sf{ length = 3 + w}

\dashrightarrow{ \sf{length = 3 + 5.5}}

\dashrightarrow{ \sf{length = 8.5  \: \: inches}}

Length of a rectangle = 8.5 inches

Hope I helped!

Best regards! :D

Select the correct answer.
In-s [12.5K]

Answer:

5-46i

Step-by-step explanation:

first multiply your (10-4i)(4-5i) so that would be 20-66i when simplified. then add that to -15+20i so it would look like 20-66i+(-15+20i). then simplify and you should get 5-46i.
