Round 176,257 to the nearest hundred thousand

Mathematics
1 answer:
Luden [163]3 years ago
6 0

The nearest hundred thousand would give you zeros after the comma in 176,257

If the number to the right of the comma in this case the "2" is 4 or less than you don't round the 6 up. If the "2" is 5 or greater than you round the 6 up by one number.

For example : 123,557 gives us 124,000

but 123,337 gives us 123,000

Therefore our answer is 176,000

The coordinates of the turning point of the parabola whose equation is y = x2 — 6x + 8 are A. (3, 35) C. (-3, 35) B. (-3, —1) D.
quester [9]

Answer:

D. (3. —1)

Step-by-step explanation:

Vertex of a quadratic function:

Suppose we have a quadratic function in the following format:

f(x) = ax^{2} + bx + c

It's vertex is the point (x_{v}, y_{v})

In which

x_{v} = -\frac{b}{2a}

y_{v} = -\frac{\Delta}{4a}

Where

\Delta = b^2-4ac

If a<0, the vertex is a maximum point, that is, the maximum value happens at x_{v}, and it's value is y_{v}.

Turning point of a quadratic function:

The turning point of a quadratic function is the vertex.

y = x2 — 6x + 8

This means that a = 1, b = -6, c = 8

Now, we find the vertex.

x_{v} = -\frac{b}{2a} = -\frac{-6}{2(1)} = 3

\Delta = b^2-4ac = (-6)^2-4(1)(8) = 36 - 32 = 4

y_{v} = -\frac{4}{4(-1)} = -1

(x,y) = (3,-1), and the correct answer is given by option D.

Rob spent 25\%25% more time on his research project than he had planned. He spent an extra hh hours on the project.
MatroZZZ [7]

Answer: 5h represents the number of hours Rob actually spent on the project.


Step-by-step explanation:

Let Rob planned that he will spend x hours in his project.

According to the question,

He spent 25% more time on his project than he planned.

That is,  his actual time = x + 25% of x = 125% of x

Again according to the question,

He spent an extra h hours on his project.

That is,  25% of x = h

\frac{25\times x}{100} = h

x=\frac{100h}{25}

x = 4h

Thus,  his actual time = 125% of x = 125% of 4h = \frac{125\times 4h}{100} = 5h

Which is the required expression.
