A0 = 7 because 2 * 5 * 7 = 70

Answer:

7

Step-by-step explanation:

x^3 + 14x^2 + 59x + 70 = (x + 2)(x + 5)(x + a_0)

Here a0 is a constant

To find the value of a0 we multiply all the constant terms and make it equal to constant 70

2 times 5 times a0  is 10a_0

10a_0=70

Divide both sides by 10

a_0= 7

So, the value of a_0 is 7

Answer:

<u>45°</u>

Step-by-step explanation:

From the diagram :

  • ∠AOC = ∠AOB + ∠BOC
  • 96 = 9x - 75 + 8x - 67
  • 17x - 142 = 96
  • 17x = 238
  • x = 238/17
  • x = 14

Finding ∠BOC :

  • ∠BOC = 8x - 67
  • ∠BOC = 8(14) - 67
  • ∠BOC = 112 - 67
  • ∠BOC = <u>45°</u>

Who is responsible for developing the punnett square
AysviL [449]
Reginald Punnett and William Bateson were among the first English geneticists. Punnett devised the "Punnett Square" to depict the number and variety of genetic combinations, and had a role in shaping the Hardy-Weinberg law. Punnett and Bateson co-discovered "coupling" or gene linkage.

Solve each equation 3x^2=80
Lapatulllka [165]

Answer:

x = \frac{4\sqrt{15}}{3}, x = \frac{-4\sqrt{15}}{3}

or

x = \frac{\pm4\sqrt{15}}{3}

Step-by-step explanation:

Hello!

Use the quadratic formula: x = \frac{-b \pm \sqrt{b^2 - 4ac}}{2a}

First, let's convert our equation to standard form of a Quadratic: ax² + bx + c = 0

3x² = 80

3x² - 80 = 0

Note, thats the value of b will be 0, as there is no "bx"

Now, solve:

  • x = \frac{-(0) \pm \sqrt{(0)^2 - 4(3)(-80)}}{2(3)}        Plug in values
  • x = \frac{\pm\sqrt{960}}{6}                              Simplify the radical (Discriminant)
  • x = \frac{\pm8\sqrt{15}}{6}                              Pull out perfect squares
  • x = \frac{4\sqrt{15}}{3}, x = \frac{-4\sqrt{15}}{3}              Reduce factors

 

The solutions are x = \frac{4\sqrt{15}}{3}, x = \frac{-4\sqrt{15}}{3}

A candle maker adds lemon oil to wax to make the lemon-scented candle shown. How many ounces of oil will he need for the candle
liraira [26]

Answer:

The ounces of oil needed is 5 ounces of oil

Step-by-step explanation:

The first thing to do here is to calculate the volume of the lemon-scented candle given.

Looking at shape the volume can be calculated using the formula L * B * H

where L(length) = 10cm , B(breadth) = 8cm and Height(h) = 25cm

The volume V is thus = 10 * 8 * 25 = 2,000 cm^3

The ounces of oil needed for the candle to have 0.0025 ounces of oil per cm^3 of wax will be = The volume of the lemon-scented candle * 0.0025 ounces of oil per cm^3 of wax

That will be = 0.0025 * 2,000 = 5 ounces
