Consider the point where the hexagons meet the positive half of the y axis.

The inner hexagon meets the axis at y=4, whereas the outer hexagon meets the axis at y = 6

So, we're looking for a dilation constant k such that

4k = 6

So, solving by k we have

k = \dfrac{6}{4} = \dfrac{3}{2}

What are the roots of the function y = 4x2 + 2x - 30?
a_sh-v [17]

Answer:

-3, 5/2

Step-by-step explanation:

What are the roots of the function y = 4x2 + 2x – 30?

To find the roots of the function, set y = 0. The equation is 0 = 4x2 + 2x – 30.

Factor out the GCF of : 2, so the equation becomes 0 = 2(2x2+x-15)

Next, factor the trinomial completely. The equation becomes: 0=2(x+3)(2x-5)

Use the zero product property and set each factor equal to zero and solve.

x+3=0      2x-5 = 0

x = -3, 5/2

The roots of the function are -3, 5/2.

Hope this helped!

How would I convert -0.5x-y+5=0 into standard form with there being no coefficient for x?
juin [17]
First put the equation into standard form by isolating y:
y=-0.5x+5
To convert x to have no coefficients, the coefficient is really 1, so multiplying everything by -2 and you get
-2y=x-10

NEED HELP will give BRAINLY
LenKa [72]

Answer:

y=1x+8

Step-by-step explanation:

  1. The best way to remember the formula is y=mx+b aka (your mom's ex bf)
  2. Just by looking at the slope you can automatically tell it's moving by one so in your formula, 'm' is the slope.
  3. Add 1x to replace 'm' or you can leave x alone because x is already one, your choice.
  4. b is the indication on where your slope started in the y-axis.
  5. In this case, by looking at the y-axis on the graph, the slope starts at 8 so that will be your b.
  6. Therefore, your answer is y=1x+8

How much money should a student place in a time deposit in a bank that pays 1.1% compounded annually so that he will have Php 20
STatiana [176]

Let us say that:<span>
   P = present value
   F = future value
    i = interest rate
   n = period

P = F / [ (1 + i ) ^n ]
P = 200000 / [ (1 + 0.011) ^6 ]
P = 187293.65

<span>Therefore the student must put up Php 187,293.65</span></span>
