I need help with this.
I need to find both A and B, I’m just lost at this point

Answer:

y = 4

Step-by-step explanation:

8 ÷ -4 = -2

so, multiply each side by -2

-2 x -2 = 4

when x = 8, y = 4

Answer:

I think the answer would be 'a'

Answer:

Step-by-step explanation:

[tex]y=-3(x^2+10x+25)-1\\ \\ y=-3x^2-30x-76\\ \\ dy=-6x-30\\ \\ d^2y=-6\\ \\ \text{Since the second derivative is always negative, when the first derivative is equal to zero the function will be at a global maximum.}\\ \\ dy=0=-6x-30\\ \\ x=-5\\ \\ f(-5)=-1\\ \\ \text{So the global maximum occurs at the point (-5,-1)[/tex]

Answer:

y= 30 x=15

set up your proportions for example 9/6 to y/20 and 9/6 to x/10 and then cross multiply

Answer:

(x+4)^2+(y-3)^2 = 85

Step-by-step explanation:

The standard form of equation of a circle is expressed as;

(x-a)^2 + (y-b)^2 = r^2

(a, b) is the center

r iis the radius

Get the radius

Radius is the distance between the two points

r^2 = (-3-3)^2 + (3-(-4))^2

r^2 - (-6)^2+(7)^2

r^2 = 36+49

r^2 = 85

Substitute (-4, 3) and r^2 = 85 into the formula

(x-(-4))^2 + (y-3)^2 = 85

(x+4)^2+(y-3)^2 = 85

This gives the required equation

Answer:

240ft

Step-by-step explanation:

You have to multiply length x width x height In this case its 12 x 4 x 5

Answer:

[tex]134 \frac{6}{5}[/tex]

Step-by-step explanation:

The computation of the distance travelled is shown below:

Total distance would be

[tex]= 52 \frac{4}{ 5} + 14 \frac{ 4}{5}\\\\= \frac{264}{5} + \frac{74}{5}\\\\= \frac{338}{5}[/tex]

Now if the same route would taken again in order to back home

So, the total distance would be doubled

[tex]= \frac{338}{5} \times 2\\\\ = \frac{676}{5} \\\\= 134 \frac{6}{5}[/tex]

Answer:

3. y=2x + 4

Step-by-step explanation:

We know that b is 4 because of the point (0,4)

Now count the slope by using rise over run

We go up 2 and over 1 so the slope is 2

Answer:

L= 90, M=53, K=37

Step-by-step explanation:

Tilt your phone/computer to the right, and you'll see the 90° angle for L. Now you're left with two more, and just compare which angle is bigger, K or M. M is bigger, so you apply the bigger number out of the you got which is 53. Now no doubts, K is 37.

Answer:

97 degrees

Step-by-step explanation:

360 degrees is our total. so:

306 - 60 - 30 - 72 - 46 - 55 = x

x = 97

Answer and Step-by-step explanation:

So, you would do 100 times 31.8, which is 3180, that'll be the area of the rectangle.

Now, the semicircles. They together form a circle.

So, we do pi times d (diameter), which is 3.14 times 31.8 = 99.852

Now we add them together.

99.852 + 3180 = 3279.85 (rounded to the nearest hundredth of a meter)

The rectangle area is 3180.

The Semi circles' combined area is 99.85.

The total area of the figure is 3279.85.

I hope this helps! Have a great day!

#teamtrees #PAW (Plant And Water)

Answer:

Step-by-step explanation:

according to the question

the area of full shape

=[tex]\text{area of the rectangle+the area of the full circle}[/tex]

=(100×31.8)+(π×(31.8/2)²)

=3180+(3.14×(15.9)²

=3180+(3.14×252.81)

=3180+793.8234

=3973.8234

=3973.82

Answer: 79

Step-by-step explanation:

6 ÷ 3 + 9 x² - 4=79

Answer:

The answer is 148 or D

Step-by-step explanation:

The line has 180 degrees total, to find the answer you subtact 32 from 180. This leaves you with 148.

Answer: x = 148°

Step-by-step explanation: All supplementary angles equal 180°. So you subtract 32° from 180° (180°-32°) and get your answer.

Answer:

part A: the warmer the city temp was the more lemonade that was sold so a hotter day will sell more lemonade

part B: i used points 40,8 and 90,20 and got m= 25/6 then i did y=mx+b

90=25/6(1)+b

90/1=25/6+b

25/6   25/6

and then B= 21.6

Step-by-step explanation: im not sure if i did it right so i would check i havent done this since like the 6th grade like 4 years or so ago lol

Answer: Choice D

They should be blocked by pain resistance so the subjects are as similar as possible.

============================================================

Explanation:

The process of blocking in statistics is where we group up people in blocks, and each block is determined by a characteristic of some sort. In this case, we're grouping people up by pain resistance level. Those very resistant to pain will be in one group, while those who easily feel pain will be in another block, and so on. It might be effective to have a pain scale and sort people by that.

Blocking is done so that we eliminate unwanted variability. We are testing the effectiveness of the itching cream, so all we care about is if the itch reduces or not. We aren't worried about the levels of pain. However, it says that "Previous studies have shown the effects of treatment may vary based on a subject's pain resistance". So we group up the people by pain tolerance to help eliminate the variability of pain tolerance levels.

This is why choice D is the final answer.

-------------

Extra info:

Answer:D

Step-by-step explanation:

This is due to the question explicitly stating how the previous studies have shown the effects of treatment may vary based on a subjects pain resistance. This leads to the only option that relates to the study's background, D

Answer:

B

Step-by-step explanation:

5/1 is not equal to 6/2 or 7/3 or 8/4

Given:

The expression is:

[tex]-1(2x+3)-2(x-1)[/tex]

To find:

The simplified form of the given expression.

Solution:

We have,

[tex]-1(2x+3)-2(x-1)[/tex]

Using distributive property, we get

[tex]-1(2x+3)-2(x-1)=-1(2x)-1(3)-2(x)-2(-1)[/tex]

[tex]-1(2x+3)-2(x-1)=-2x-3-2x+2[/tex]

On combining like terms, we get

[tex]-1(2x+3)-2(x-1)=(-2x-2x)+(2-3)[/tex]

[tex]-1(2x+3)-2(x-1)=-4x-1[/tex]

Therefore, the simplified form of the given expression is [tex]-4x-1[/tex].

Note: The correct option is not available.
