Answer:

x = -6,6

Step-by-step explanation:

h(x)=−5x^2 +180

Assuming you want to find the zero's

0 =−5x 2 +180

Subtract 180 from each side

0-180=−5x^2 +180-180

-180 = -5x^2

Divide each side by -5

-180/-5 = -5x^2/-5

36 = x^2

Take the square root of each side

±sqrt(36) = sqrt(x^2)

±6 = x

x = -6,6

Answer:

-6, 6

Step-by-step explanation:

h(x) = -5x² + 180

-5x² + 180 = 0

x² = 36

x = -6, 6

Find a third-degree polynomial function with real coefficients and with zeros at -4 and -3 5i
Charra [1.4K]

If -3+5i is a solution, then by the conjugate root theorem, -3-5i is also a solution. We find the polynomial by multiplying together the factors. If x = -4, then x + 4 is the factor. If x = -3+5i, then (x-(-3+5i)) is a factor, and so is (x-(-3-5i)). Simplifying those down gives us as the first factor as (x+3-5i) and the second as (x+3+5i). We can FOIL those 2 together to get their product, and then FOIL in x+4. FOILing the 2 complex factors together gives us x^2+3x+15ix+3x+9+15i-15ix-15i-25i^2. If we combine like terms and cross out things that cancel it's much easier than what it looks like there! It simplifies down to x^2+6x-25i^2. Since i^2 = -1, it simplifies further to x^2+6x-25(-1) and finally, to x^2+6x+25. Now we will FOIL in x+4. (x^2+6x+25)(x+4)=x^3+6x^2+25x+4x^2+24x+100. Our final simplified third degree polynomial is x^3+10x^2+49x+100

Solve for −4.2y+2.1>−2.52
Alchen [17]

Answer:

y < 1.1

Step-by-step explanation:

<u>Step 1:  Subtract 2.1 from both sides </u>

-4.2y + 2.1 - 2.1 > -2.52 - 2.1

<em>-4.2y > -4.62</em>

<em />

<u>Step 2:  Divide both sides by -4.2</u>

-4.2y / -4.2 > -4.62 / -4.2

<u><em>Since you divided by a negative, that flips the sign.</em></u>

<em>y < 1.1 </em>

Answer:  y < 1.1

Write each of the following numerals in base 10. For base​ twelve, T and E represent the face values ten and​ eleven, respective
elena-s [515]

Answer:

  a. 37

  b. 25

  c. 226

Step-by-step explanation:

Place value has the same meaning in any other number base that it has in base 10. Using expanded form is one way to do the required base conversion.

a. 122₅ = 1×5² +2×5¹ +2×5⁰

   = 25 +10 +2 = 37

__

b. 11001₂ = 1×2⁴ +1×2³ +0×2² +0×2¹ +1×2⁰

   = 16 +8 + 1 = 25

__

c. 16T₁₂ = 1×12² +6×12¹ +10×12⁰

   = 144 +72 +10 = 226
