You start at (1, 0). You move up 4 units and down 2 units. Where do you end?
melisa1 [442]

Answer:

(1, 2)

Step-by-step explanation:

You are moving up 4 units, so that means you need to add to the y coordinate, which is 0.  0 + 4 = 4

The new coordinate is (1, 4)

Now you move down 2 units, that means you need to subtract from the y coordinate, which is now 4. 4 - 2 = 2

You will end at (1, 2)

AM and AN are tangent to circle C. If AM measures 2.5 cm, what is the measure of AN?
Vera_Pavlovna [14]

The measure of AN form the given figure is 2. 5cm. Option D

<h3>How to determine the length</h3>

It is important to note that if from one external point, two tangents are drawn to a circle then they have equal tangent segments.

We have that,

AM ≅ AN

so, if AM  measures 2. 5cm

AN measures 2. 5cm

Thus, the measure of AN form the given figure is 2. 5cm. Option D

Given that x=1.5 is the only solution to the equation 4x^2 - ax + b = 0, find the values of a and b. Show all workings.
evablogger [386]
If x = 1.5 is the only solution to the equation 4x² - ax + b =0 then

4x² - ax + b = 4(x - 1.5)²      |use p² - 2pq + q² = (p - q)²

4x² - ax + b = 4(x² - 2x · 1.5 + 1.5²)

4x² - ax + b = 4(x² - 3x + 2.25)

4x² - ax + b = 4x² - 12x + 9  |subtract 4x² from both sides

-ax + b = -12x + 9

therefore

-a = -12 ⇒ a = 12 and b = 9

A designer places 4 identical squares on a surface and spaces them 3 5/16 inches apart. Each square is 7 1/4 inches wide. If you
Anon25 [30]

Number of spaces would be number of squares - 1

You would have 12 squares and 11 spaces.

Multiply number of each by their size then add the two together:

12 x 7 1/4 = 87 inches

11 x 3 5/16 = 36 7/16 inches

Total = 87 + 36 7/16 = 123 7/16 inches

Answer: 123 7/16 inches
