Answer:
m=47 n=52
Step-by-step explanation:
To solve this problem you must apply the proccedure shown below:
1. You have that the <span>parabola is 12 meters high at the vertex and at a height of 10 meters, the width is 8 meter.
2. Therefore, you have:
x^2=-4a(y^2-k)
4</span>^2=-4a(10-12)
16=-40a+48
16=8a
a=16/8
a=2
y=0
x^2=-8(0-12)
x^2=96
x=√96
x=9.79x2
x=19.58
3. Therefore, as you can see, the answer is: 19.58 meters.<span>

<u>In sentence 7, the </u><u>phrase</u><u> by all accounts is best replaced by </u><u>however.</u>
Correct option is A
- The sentence that precedes 7 states something that is in contrast with it.
- Therefore 'by all accounts' in sentence should be changed to 'however' as it is generally used to present something that is different from or contrasts with the previous statement.
- Thus A is the best answer. The other options are incorrect because they do not convey the contrast that is required in the given context.
What is a phrase in grammar?
- In syntax and grammar, a phrase is a group of words which act together as a grammatical unit.
- For instance, the English expression "the very happy squirrel" is a noun phrase which contains the adjective phrase "very happy".
- Phrases can consist of a single word or a complete sentence.

To find the answer you must know what 3x - 2y=
Answer:
a = 4 + -1.333333333b
Step-by-step explanation:
Simplifying
3a + 4b = 12
Solving
3a + 4b = 12
Solving for variable 'a'.
Move all terms containing a to the left, all other terms to the right.
Add '-4b' to each side of the equation.
3a + 4b + -4b = 12 + -4b
Combine like terms: 4b + -4b = 0
3a + 0 = 12 + -4b
3a = 12 + -4b
Divide each side by '3'.
a = 4 + -1.333333333b
Simplifying
a = 4 + -1.333333333b
