Answer:

x = -6.00 (rounded to nearest hundredth)

Step-by-step explanation:

  • for a quadratic equation, h(x)=ax^2+bx+c  
  • we have f(x)=x^2+12x+31.5
  • a = 1
  • b = 12
  • to find minimum use equation x=\frac{-b}{2a}
  • x=\frac{-b}{2a}\\x=\frac{-(12)}{2(1)}\\x=\frac{-12}{2}=-6

#5 The MAC is 4 centimeters. Find the circumference of B. Round your answer to the hundredths.
bixtya [17]

Answer:

C ≈ 11.71 cm

Step-by-step explanation:

using the ratio arc  AC : circumference C = angle at centre of sector : 360°

\frac{AC}{C} = \frac{123}{360} , that is

\frac{4}{C} = \frac{123}{360} ( cross- multiply )

123 × C = 4 × 360 = 1440 ( divide both sides by 123 )

C = \frac{1440}{123} ≈ 11.71 cm ( to the nearest hundredth )

What is the answer ,and how do you solve it .please help
xz_007 [3.2K]

Answer:

10

Step-by-step explanation:

2000/ 2x = 10

Multiply each side by 2x

2000/ 2x = 10 *2x

2000 = 20x

Divide by 20

2000/20 = 20x/20

100 = x

Take the square root of each side

sqrt(100) = sqrt(x)

10 = sqrt(x)

Sam and Annika ride their bikes to school. Sam rides his bike (K )kilometers. Annika rides her bike two less than four times as
Gekata [30.6K]
S=k, a=4k-2

Annika rides her bike so she must travel some positive distance, ie a>0 so:

4k-2>0

4k>2

k>1/2  and that k is how far Sam rode, so Sam must ride his bike more than 1/2 kilometer.
