How to graph the equation y=1/4x-6

Answers

$y= (1)/(4)x-6 \n \nx=-8 \Rightarrow y=(1)/(4)* (-8)-6=-2-6=-8\n \nx=-4 \Rightarrow y=(1)/(4)* (-4)-6=-1-6=-7\n \nx=0 \Rightarrow y=(1)/(4)* 0-6=0-6=-6\n \nx=4 \Rightarrow y=(1)/(4)*4-6=1-6=-5 \n \nx=8 \Rightarrow y=(1)/(4)*8-6= 2-6=-4$

A baker uses a coffee mug with a diameter of 8\text{ cm}8 cm8, start text, space, c, m, end text to cut out circular cookies from a big sheet of cookie dough.What is the area AAA of each cookie?

Give your answer in terms of pi.

\text{cm}^2cm

2

start text, c, m, end text, squared

Answers

Answer:

Step-by-step explanation:

Since the cookies is circular in nature, we will use the formula for calculating the area of circle to calculate the area if each cookies.

Area of each cookies = πd²/4

Given diameter d = 8cm

Area of the cookies = π(8)²/4

Area of the cookies = 64π/4

Area of the cookies = 16π cm²

Answer:

16 pi ^2

Review the incomplete derivation of the cosine sum identity.A 2-column table with 5 rows. Column 1 has entries step 1, step 2, step 3, step 4, step 5. Column 2 has entries cosine (x + y), sine (StartFraction pi Over 2 EndFraction minus (x + y) ), blank, sine (StartFraction pi Over 2 EndFraction minus x) cosine (negative y) + cosine (StartFraction pi Over 2 EndFraction minus x) sine (negative y), blank.

Which expressions for Step 3 and Step 5 complete the derivation?

Step 3: Sine ( (StartFraction pi over 2 EndFraction minus x) + y )
Step 5: cos(x)cos(y) + sin(x)sin(y)
Step 3: Sine ( (StartFraction pi over 2 EndFraction minus x) + y )
Step 5: cos(x)cos(y) – sin(x)sin(y)
Step 3: Sine ( (StartFraction pi over 2 EndFraction minus x) minus y )
Step 5: cos(x)cos(y) + sin(x)sin(y)
Step 3: Sine ( (StartFraction pi over 2 EndFraction minus x) minus y )
Step 5: cos(x)cos(y) – sin(x)sin(y)

Answers

Answer:

Option (4)

Step-by-step explanation:

STEP - 1

cos(x + y)

STEP - 2

$\text{sin}[(\pi)/(2)-(x+y)]$

STEP - 3

$\text{sin}[((\pi)/(2)-x)-y]$

STEP - 4

$\text{sin}((\pi)/(2)-x)\text{cos}(-y)+\text{cos}((\pi)/(2)-x)\text{sin}(-y)$

STEP - 5

cos(x)cos(y) - sin(x)sin(y)

[Since, $\text{sin}((\pi)/(2)-x)=cos(x)$ and $\text{cos}((\pi)/(2)-x)=\text{sin}(x)$ ]

[Since, cos(-x) = cos(x) and sin(-x) = -sin(x)]

Therefore, Option (4) will be the correct option.

What two numbers adds to -31 and multiplies to 150

Answers

In order to add to a negative number but multiply to a positive number, both numbers must be negative.
With a large number such as 150, I sometimes find it helpful to factor all possible combinations.
150
-----
-1 × -150 ll -1 - 150 = -151
-2× -75 ll -2-75 = -77
-3× -50 ll -3-50 = -53
-5× -30 ll -5-30 = -35
-6× -25 ll -6-25 = -31
-10× -15 ll -10-15 = -25

The numbers are -6 and -25
-6 -25 = -31
-6 × (-25) = 150

I apologize for any poor formatting

How do you graph y=18

Answers

y = 18 is just a straight horizontal line at (0,18)

Answer:

Use the slope-intercept form to find the slope and y-intercept

Any line can be graphed using two points. Select two x

values, and plug them into the equation to find the corresponding y

values. Graph the line using the slope and the y-intercept, or the points.

Slope: 2

y-intercept: 18
