Answer: A) True because the leading coefficient is negative
Explanation:
The leading term is -x^2 since this term has the largest exponent.
The leading coefficient is -1 as it's the coefficient of the leading term.
It might help to write -x^2 as -1x^2
The negative leading coefficient makes the parabola open downward, so each endpoint goes off to negative infinity. The graph looks like a frowny face. You can think of a negative emotion going with a frowny face, so that negative emotion matches with the negative leading coefficient. There are probably other ways to remember but that's the trick I use.

Find the measure of the exterior angle.
64
76
Using the exterior angles theorem, the measure of the exterior angle(k) is 140 degrees.
How to find the exterior angles of a triangle?The exterior angle theorem states that the measure of an exterior angle is equal to the sum of the measures of the two remote interior angles of the triangle.
The two remote interior angles are 76 degrees and 64 degrees.
Therefore,
76 + 64 = k
k = 140 degrees.

explain how to convert decimal form into fractional form
Answer:
To convert a decimal to a fraction, place the decimal number over its place value. For example, in 0.6, the six is in the tenths place, so we place 6 over 10 to create the equivalent fraction, 6/10. If needed, simplify the fraction.

Answer:
x=45.6
Step-by-step explanation:
(2x-2)+x+45=180
Combine like terms.
3x+43=180
Subtract 43 on both sides.

-43 -43
3x=137
Divide by 3 on both sides.

Answer: 8
Step-by-step explanation: i took the test
1.25 days would be taken for 3 men to complete the same job.
What is Ratio?A ratio is an ordered pair of numbers a and b, written a / b where b does not equal 0.
Given that 12 men 5 days to complete a job
We have to find for how many days three men can complete the same job.
Let x be the time taken by 3 men to complete the job.
Formulate a proportional equation.
12/5=3/x
Apply cross multiplication
12x=15
Divide both sides by 12
x=15/12
both 15 and 12 are multiples of 3
x=5/4
x=1.25
Hence, 1.25 days would be taken for 3 men to complete the same job.

A plot of land is valued at $18,000.Land tax is charged at the rate of 0.70 per $100. What is the total amount of tax paid for the land?
Answer:
The total amount of tax paid for the land was $126
Step-by-step explanation:
Proportions
The land tax charged is 0.7 per each $100 of the land value. For easy calculations, we find the ratio or proportion to be applied to the value of the land as:
0.7 / 100 =0.007
This factor can be used to obtain the tax charged for a given value of the land.
The plot of land of the question is valued at $18,000.
The tax charged is, then:
0.007*18,000 = 126
The total amount of tax paid for the land was $126

Use the formula an = d (n − 1) + aj to write a formula for the arithmetic sequence below.
2, 6, 10, 14, 18,
Answer:
[tex]a_{n}[/tex] = 4n - 2
Step-by-step explanation:
There is a common difference d between consecutive terms in the sequence, that is
6 - 2 = 10 - 6 = 14 - 10 = 18 - 14 = 4
This indicates the sequence is arithmetic with n th term
[tex]a_{n}[/tex] = a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Here a₁ = 2 and d = 4 , thus
[tex]a_{n}[/tex] = 2 + 4(n - 1) = 2 + 4n - 4 = 4n - 2

4. Square ABCD is shown. What is the length of diagonal AC? Round to the nearest tenth, if necessary.
Answer:
hey! You have to use the trigonometric formula because it's a rectangle triangle:
(a^2)+(b^2)=(c^2)
(11^2)+(11^2)=(c^2)
√(242)=√(c^2)
15.56=c
So basically, the answer is D!
The square ABCD has equal sides, and the length of the diagonal AC is 15.6 centimeters
How to determine the length of the diagonal?The side length of the square is given as:
l = 11 cm
The length of the diagonal is calculated using:
Diagonal = l * √2
This gives
Diagonal = 11 * √2
Evaluate
Diagonal = 15.6
Hence, the length of the diagonal AC is 15.6 centimeters
