Answer:

  {-1.47, 1.14}

Step-by-step explanation:

The solution to ...

  ax^2 +bx +c = 0 is ...

  x=\dfrac{-b\pm\sqrt{b^2-4ac}}{2a}

Filling in the values a=3, b=1, c=-5, the solutions are ...

  x=\dfrac{-1\pm\sqrt{1^2-4(3)(-5)}}{2(3)}=\dfrac{-1\pm\sqrt{61}}{6}\\\\\boxed{x\approx\{-1.47,1.14\}}

Each output value is equal to the square of the input value minus<br> five
Ivenika [448]

i think that A pair of an input value and its corresponding output value is called an ordered pair and can be written as (a, b). In an ordered pair the first number, the input a, corresponds to the horizontal axis and the second number, the output b, corresponds to the vertical axis.

We can thus write our values as ordered pairs

(0, 0) - This ordered pair is also referred to as the origin

(1, 2.5)

(2, 5)

(3, 7.5)

These ordered pairs can then be plotted into a graph.

EXPAND THE POLONOMIAL <br><br> (5a+1/2b)^2 HELPPP ASAP
stepan [7]

Answer:

25a^{2}+5ab+\frac{b^{2} }{4}

Step-by-step explanation:

(5a+\frac{1}{2} b)^{2}

1. First, write out the expression without the square

(5a+\frac{1}{2} b)(5a+\frac{1}{2} b)

2. Then use foil to multiply:

5a*5a+5a*\frac{1}{2}b+\frac{1}{2}b*5a+\frac{1}{2}b*\frac{1}{2}b

=25a^{2}+5ab+\frac{b^{2} }{4}

3. That is your answer.

morpeh [17]

Answer:

No, because the cone has a smaller volume than the ice cream

Step-by-step explanation:

V=4

3πr3=4

3·π·33≈113.09734

Volume of scoop: 113.1 cm^2

V=πr2h

3=π·2.52·10

3≈65.44985

Volume of cone: 65.45 cm^2

65.45 < 113.1

I WILL MARK BRAINLIST!! HURRY HELP!! PEASE THANK YOUU
ZanzabumX [31]

Given that a rectangle has an area of 345 square millimeters and a base of 15 millimeters, find the height.

Area of a Rectangle = b x h

So, to find the height, we would reverse it by dividing the area by the base.

Work:

345/15 = 23

So, 23 would be our height.

Thus, the height of the rectangle is 23 millimeters.
