(pls help)

Answers

Answer:

A) 70

Step-by-step explanation:

180 - 120 = 60

? = x

x + 50 + 60 = 180

x + 110 = 180

x = 70

So we need it to equal 120
120-50 is 70
So your answer is 70

Remember that the formula is f(x) = a(x-h)^2+k.

1/2: The closer to zero the value, the wider, so this will stretch vertically.

5: Which means that h=5, so the graph is shifting left 5 units.

7: this means that k=7, so the graph is shifted up 7 units.

The answer is stretched vertically, shifted left 5 units, shifted up 7 units.

[tex]2x-7y=9\\x+2y=10[/tex]

Answers

Answer:

x=8 y=1

Step-by-step explanation:

you have first and second equation, YOU MUST FIND THE THIRD EQUATION

SOLUTION

FIND equation 3 from 2

x+2y=10

x=10-2y...........3

Substitute equation 3 from first (not from the equation where you got equation 3)

2 (10-2y)-7y=9

20-4y-7y=9

-11y=9-20

-11y= -11

-11y/-11= -11/-11

y=1

b is directly proportional to a.
b is 10 when a is 8.
Work out b when a is 9.

Answers

Answer:

B=11

Step-by-step explanation:

b=10 a=8

b=? a=9

Either you can cross multiple 10x9=90/8 (11.25, round down to 11), or you can look that 9 is 8+1, so of we do the same process to b then we would find our awnser. 10+1=11.

When a is 9 then, the value of b will be;

⇒ b = 45/4

What is Proportional?

Any relationship that is always in the same ratio and quantity which vary directly with each other is called the proportional.

Given that;

'b' is directly proportional to a.

And, b is 10 when a is 8.

Now,

Since, 'b' is directly proportional to a.

Hence, We get;

⇒ b = ka

Where, k is constant of proportionality.

Here, b is 10 when a is 8.

So, Put b = 10 and a = 8;

⇒ b = ak

⇒ 10 = k × 8

⇒ k = 10 / 8

⇒ k = 5/4

So, When a is 9 and k is 5/4, then;

⇒ b = ak

⇒ b = 9 × 5/4

⇒ b = 45/4

Thus, The value of b = 45/4

Please help! I do not know how to find the unknown variables using the Pythagorean theorem. Any help will be greatly appreciated:))

Answers

Answer:

x=10.247

y=52.02

z=37.98

Step-by-step explanation:

For x you use Pythagorean theorem which, in this situation would be 13^2=8^2+x^2 rearranging this we can figure out x by taking the square root of 13^2-8^2.

For y you can use any trig function but I chose to use cos since that uses info we're given, to find y you just do the inverse cos or cos^-1 of 8/13 to find the angle

For z you can use any trig function but I chose to use sin since that uses info we're given, to find z you just do the inverse sin or sin^-1 of 8/13 to find the angle

y = 20 + 35x or y = 35x + 20

Step-by-step explanation:

Looking at the problem, a cell phone company charges $20 for a new account, and $35/month for phone service. With that information we can quickly form this equation:

y = 20 + 35x

The y is the total cost, 20 is the initial charge, and 35x is the per-month charge.

Step-by-step explanation:

Given

n² + 4n - 12

Consider the factors of the constant term (- 12) which sum to give the coefficient of the n- term (+ 4)

The factors are + 6 and - 2 , since

6 × - 2 = - 12 and 6 - 2 = + 4

Then

Caenorhabditis elegans is an approximately 1 mm long nematode (worm) that lives in the soil and eats bacteria such as Pseudomonas. Scientists have determined that when C. elegans is hunting for food, the worms have different patterns of movement that depend on the location and quality of the food source. Scientists hypothesized that C. elegans might be attracted to certain chemicals produced by Pseudomonas. They tested this hypothesis by placing 100 C. elegans in the center of each of a series of petri dishes containing a layer of agar over which the worms could move. A drop of a test chemical diluted in ethanol was placed at one edge of each dish and an equal-sized drop of ethanol was placed at the opposite edge of the dish. The scientists determined the number of worms to reach each spot over a period of time.(a) Describe why the location and quality of food sources in the soil are sometimes likely to stimulate random movements by C. elegans, but at other times are more likely to stimulate directed movements(b) Justify the scientists use of two different spots on each petri dish and the counting of worms at each of the two spots.(c) Under harsh environmental conditions, C. elegans produces a pheromone, a complex of molecules that affects other C. elegans. One effect of the pheromone is to cause developing larvae to temporarily arrest as larvae rather than mature to reproductive adults. Predict the relative amount of pheromone most likely produced by C. elegans that are only weakly attracted to one of the test chemicals.(d) Provide reasoning to justify your prediction with respect to how the predicted amount of pheromone is beneficial to the worms that are only weakly attracted to the chemical. cash-apping $5 to who ever finishes this correctly TO KILL A MOCKINGBIRD BY HARPER LEE QUESTIONS---Prompt: At the end of Part One, Atticus claims that its a sin to kill a mockingbird (Lee 119). Defending Atticuss statement, Miss Maudie later explains, Mockingbirds dont do one thing but make music for us to enjoy. They dont eat up peoples gardens, dont nest in corncribs, they dont do one thing but sing their hearts out for us. Thats why its a sin to kill a mockingbird (Lee 119).

List which two characters you will be arguing are mockingbird characters:I chose Boo Radley and Tom Robinson1B. Write bullet points on why they are considered "mockingbirds"1C. Cite Evidence + Chapter# Page# + Go back to previous events in the book.2. For the first character you choose, explain why they are a mockingbird character. Make specific reference to the text. (For example, do not simply say, Sally is a mockingbird character because she is nice. You should say, Sally is a mockingbird character because she did X and did not do Y.)3. Repeat step 2 for the second character you chose:4. Now, craft your thesis statement using the information above. (Example: So-and-so and so-and-so are mockingbird characters because [state a succinct summary of the reasons you chose Character 1 and Character 2])5. Your thesis should be a single sentence. Now, for your roadmap (which comes right after the thesis statement) you can explain yourself a bit more, giving specific examples or reasons why you made your claim. Write your roadmap below.Example: [Thesis statement:] Sally and Bert are both mockingbird characters because they fly and enjoy singing. [Roadmap:] Sally routinely flies over the neighborhood in her private jet, while Bert sits on Lucindas kitchen window and croons hits from the 50s.
