2. How many ounces of Ceylon tea worth $1.50 per ounce

Mathematics
1 answer:
gregori [183]3 years ago
4 0

Answer: How many ounces of ceylon tea worth 1.50 per ounce and how many ounces of formosa tea worth 2.00 per ounce must be mixed to obtain a mixture of 8 ounces that is worth 1.85 per ounce

Equation:

1.5c + 2f = 1.85*8

c + f = 8

Modify:

1.5c + 2f = 1.85*8

2c + 2f = 16

Subtract and solve for "c":

0.5c = 1.2

c = 2.4 ounces (amt. of ceylon tea needed)

Solve for "f":: c + f = 8, so f = 5.2 ounces

Which equation represents the function on the graph?
Marrrta [24]

Answer:

A. Sin 2x

Step-by-step explanation:

This is a trig function and has the shape of sine or cosine. Since it intersects at (0,0), it is likely a sine graph. A normal sine graph starts at (0,0), crests up at 1, and crosses back down at the x-axis at (3.14, 0). However, this graph starts at (0,0) and crosses back again at half that value. This graph has been horizontally compressed by multiplication of a number greater than 1. So this graph is Sin 2x.

Answer:

  • k = -4 ± 2√5

Step-by-step explanation:

#22

<h3>Given </h3>
  • Equation x² -4x + 1 = k(x - 4) with equal roots
<h3>To find</h3>
  • The value of k
<h3>Solution</h3>

<u>The equation in standard form is:</u>

  • x² -4x + 1 = k(x - 4)
  • x² - 4x - kx + 1 + 4 = 0
  • x² - (k + 4)x + 5 = 0

<u>When the quadratic equation has equal roots its discriminant is zero</u>

  • D = 0
  • b² - 4ac = 0
  • (k + 4)² - 4*5 = 0
  • (k + 4)² = 20
  • k + 4 = ± √20
  • k = - 4 ± √20
  • or
  • k = -4 ± 2√5

Find the equation of a line passing through the point (2, 3) and having a slope of 3.
Delvig [45]

Answer:

The answer to your question is the letter B) y = 3x - 3

Step-by-step explanation:

Data

Point = (2, 3)

slope = m = 3

Process

To solve this problem just substitute the values given in the slope-point equation.

Formula

               y - y1 = m(x - x1)

   x1 = 2      y1 = 3

-Substitution

              y - 3 = 3(x - 2)

-Expand

              y - 3 = 3x - 6

-Solve for y

             y = 3x - 6 + 3

-Result

             y = 3x - 3
