Answer:

he rose by 71 feet and it took him 6.88 mins to do so.

Step-by-step explanation:

So we know that the diver is going up in elevation cause he is ascending and he ascended 71 ft. Along with the fact that the total dive was 20 1/8 mins with roughly converts to 20.13 mins and if we take that number and subtract the amount of time he stayed at the elevation of 71ft we know that it took him 6.88 min to rise to the elevation of -18.9.

If the domain of the coordinate transformation (, ) = ( + 2,− − 4) is (1, -4), (3, -2), (0, −1), what is the range?

timama [110]

Answer:

A. (-2, -5), (0, -7), (1, -4)

Step-by-step explanation:

The following transformation is applied:

$(x,y) \rightarrow (y + 2, -x - 4)$

To find the range:

We apply the transformation to the points in the domain. Thus:

$(1,-4) \rightarrow (-4 + 2, -1 - 4) = (-2, -5)$

$(3,-2) \rightarrow (-2 + 2, -3 - 4) = (0, -7)$

$(0,-1) \rightarrow (-1 + 2, 0 - 4) = (1, -4)$

Thus the correct answer is given by option a.

</span>(2x^2 - 5x + 4) Original Mathematical Expression

[2(7)^2 - 5(7) + 4] Plugging the value of x, 7 into expression.

There are parentheses, so that means we have to work in them.

There are exponents, so we have to do those first.

[2(49) - 5(7) +4] Exponents.

There is multiplication, that we can do, so we do that left to right.

[98 - 35 + 4] Multiplication.

There is no division.

There is addition and subtraction, so we do those left to right.

[63 + 4] Subtraction.

67 Addition.

Vika [28.1K]

Answer:

9/25

Step-by-step explanation:

find a number that both the top and bottom are divisible by,

23 is the greatest common division we can make such that the top and bottom remain whole numbers

so,

$\frac{207 }{575}$ ÷23

=(207/23)÷(575/23)

= $\frac{9}{25}$

How to justify each step in the solution of 5x+15=0

velikii [3]

Answer:

Step-by-step explanation:

The given equation is:

5x+15 =0

Subtract 15 from both sides:

5x+15-15= 0-15

By solving the like terms we get:

5x=-15

Divide both sides by 5

5x/5 = -15/5

Simplify:

x= -3...
