Given that the zeros of a quadratic function are −2 and −5, what is the standard form of the quadratic function? A) f(x) = x2 + 5x + 10 B) f(x) = x2 + 7x + 10 C) f(x) = x2 − 5x + 10 D) f(x) = x2 − 7x + 10
Step-by-step explanation:
x = -2 and x = -5
x + 2 = 0 and x + 5 = 0
(x + 2)(x + 5) = 0
x² + 5x + 2x + 10 = 0
x² + 7x + 10 = 0

3 less than the quotient of a number and 5 is -7
Answer: The number is -20
Step-by-step explanation:
Take each part of the sentence and write what it is telling us:
3 less than the quotient of a number and 5 is -7
The quotient of a number and 5 is (X/5), where X is the "number."
3 less than is (X/5) - 3
is -7 is = -7
Therefore:
3 less than the quotient of a number and 5 is -7 is: (X/5) - 3 = -7
---
(X/5) - 3 = -7
(X/5) = -4
X = -20
===
See if this works:
3 less than the quotient of -20 and 5 is -7
(-20/5) = -4
Three kless than -4 is -7: It works

Answer:
the three sides are 8, 12 and 16
Step-by-step explanation:
since the ratio is in 2:3:4, we need to work out each side individually so add them=2+3+4=9
9n=36, n=4
2:3:4
2 × 4 = 8
3 × 4 = 12
4 × 4 = 16
A rope is stretched tight between the tops
of two flag poles. One pole is 16 m tall, the
other is 8 m tall and they stand on level
ground 6 m apart. Find the rope's length.
m
Answer:
10 m.
Step-by-step explanation:
We have a triangle with hypotenuse h m (the rope's length) and one leg 16 - 8 = 8 m and the other 6 m.
So h^2 = 8*2 + 6^2 = 100
h = 10 m.

1. Find the x and y intercept for the function 3x-4y=12
Step-by-step explanation:
To easily solve this problem we need to know two facts:
the y-intercept is 'c' when a line is in the slope-intercept form (y = mx + c)the x-intercept occurs when y = 0Slope-intercept form
Since 3x - 4y = 12
3x - 12 = 4y
y = ³/₄ x - 3
∴ y-intercept is (0, -3)
Solve for x when y = 0
Since 3x - 4y = 12
3x - 4(0) = 12
x = 4
∴ x-intercept is (4, 0)
We can check our answer by graphing the line and seeing if it passes through the intercepts we calculated. Since it does (see graph below), then the answers we calculated are correct.

*How much money was in Caroline's account when it was opened? Explain.
*After 2 years, how much money would Caroline have saved? (Hint - convert years to months before solving). To earn full credit, show your work using a method explained in the Orientation.
Answer:
A) $3100
B) $6700
Step-by-step explanation:
A)The first table entry is the value of the opening balance of Caroline's account.
$3100 was in Caroline's account when it was opened.
__
B)After 1 month, the balance in Caroline's account increased by $3250 -3100 = $150. There are 12 months in a year, so after 2 years, Caroline will have made 12×2 = 24 additional deposits of $150. Her account value will be ...
24 × monthly deposit + initial balance
= 24 × $150 + $3100 = $3600 +3100 = $6700
Caroline would have saved $6700 after 2 years.

Answer:
Find the first term:
The first term is 5
Is the sequence arithmetic?
Yes because (5 -7 = -2) (-2 - 7 = -9)
Find the common difference d:
The common difference is -7
Find the general term an:
[tex]a_{n}[/tex] = (first term) + ((nth term) -1) · (common difference)
[tex]a_{n}[/tex] = 5 + (n - 1) · (-7)
Find the 20th term:
[tex]a_{20}[/tex] = 5 + (20 - 1) · (-7)
= -128
Find the sum of the first 50 terms:
[tex]a_{50}[/tex] = 5 + (50 - 1) · (-7)
= -338

The table shows the approximate height of a football after it is kicked. Tell whether the rates of change for successive time intervals are constant or variable.
Answer:
36, 14, -12
variable
Step-by-step explanation:
1st Rate of change is 18 - 0 / 0.5 - 0 = 18/0.5 = 36
2nd rate of change is 32 - 18 / 1.5 -0.5 = 14 / 1 = 14
3rd rate of change is 26 - 32 / 2 - 1.5 = -6/0.5 = -12
so the rates of change are variable

Lucy can type 300 words in 5 minutes. How many words can Lucy type in 27 minutes?
Answer:
1620 wordsStep-by-step explanation:
Given,
Number of words Lucy can type in 5 minutes
= 300 words
So,
Number of words Lucy can type in 1 minute
[tex] = \frac{300}{5} \: words[/tex]
= 60 words
Therefore,
Number of words Lucy can type in 27 minutes
= (60 × 27) words
= 1,620 words
Hence, Lucy can type 1620 words in 27 minutes.
objectivity in the interpretation of data is referred to as
In philosophy, objectivity is a central concept that generally denotes an objective and impartial approach to something. The opposite is subjectivity.
That something is objectively true, an objective truth, means that it is true regardless of subjectivity. Objectivity is usually an ideal in connection with research, as the result is expected to be as independent of the researcher's opinions or ideas as possible.
Objectivity is often also emphasized as a basic ideal in journalistic work. An important question in philosophy is whether it is possible to experience something objectively.

Answer:
$55
Step-by-step explanation:
Since we are not given much information in this problem, we know this must be a pretty simple sequence. If we make a sequence of Natural Numbers and match it up to the prices we've been given, we get
1,2,3,4...
5,10,15...
The price is increasing by five dollars for every "n", so our sequence is just 5n. Extrapolating this out gives us $55 for n=11
