Answer:

[tex]f(x)=x^2+9x-10[/tex]

Step-by-step explanation:

Standard Form of Quadratic Function

The standard representation of a quadratic function is:

[tex]f(x)=ax^2+bx+c[/tex]

where a,b, and c are constants.

The factored form of a quadratic equation is:

[tex]f(x)=a(x-\alpha)(x-\beta)[/tex]

Where [tex]\alpha[/tex] and [tex]\beta[/tex] are the roots or zeros of f.

The question gives the zeros of the function: 1 and -10. This makes our function look like:

[tex]f(x)=a(x-1)[x-(-10)][/tex]

[tex]f(x)=a(x-1)(x+10)[/tex]

Operating:

[tex]f(x)=a(x^2+10x-x-10)[/tex]

Joining like terms:

[tex]f(x)=a(x^2+9x-10)[/tex]

Since we are not given any more conditions, we choose the value of a=1, thus. the required function is:

[tex]\boxed{f(x)=x^2+9x-10}[/tex]

also i took the quiz got 100

Answer:

Its c

Step-by-step explanation:

because 96 divided by 12 equals 8

Answer:

the answer is 700

Step-by-step explanation:

it's 700 because 100% of 700 is 700,therefore 3 percent of 700 equals 21

2(x - 4) + 2x = 18, where x represents the width.

2x - 8 + 2x = 18 (Distribute 2)

4x - 8 = 18 (Add like terms)

4x = 26 (Add 8 to both sides)

x = 6.5 (Divide 4 from both sides)

Length = x - 4 (Length is 4 less m than Width [x - 4])

6.5 - 4 = 2.5 (Substitue in x)

Length = 2.5

The length is 2.5 meters and the width is 6.5 meters.

You can check by adding 2.5 + 2.5 + 6.5 + 6.5 = 18.

The isosceles triangle theorem states that if two sides of a triangle are congruent, then the angles opposite those sides are congruent. That is option D.

An isosceles triangle theorem states that if two sides of a triangle are congruent, then the angles opposite to these sides are congruent.

This is because the two side of the triangle are identical leading to the angles opposite them being equal too.

Therefore, the isosceles triangle theorem states that if two sides of a triangle are congruent, then the angles opposite those sides are congruent.

Answer:

400+4n ≥ 750; The club will need to raise an average of $87.50 or more per month.

Step-by-step explanation:

The inequality will be 400+4n ≥ 750 and the club will need to raise an average of $87.50 or more per month.

When two expressions are connected by a sign like "not equal to," "greater than," or "less than," it is said to be inequitable. The inequality shows the greater than and less than relation between variables and the numbers.

Given that a school chess club needs to raise at least $750 to attend a state competition. The club has already raised $400 and there are 4 months remaining until the competition.

The inequality will be written as,

400+4n ≥ 750

4n ≥ 750 - 400

4n ≥ 350

n ≥  350 / 4

n ≥  $87.5

-51/5 and √64 are rational, the rest are irrational

Step-by-step explanation:

Irrational numbers are numbers that never end; 9.68, line of the 8 means the number would be 9.6888888888... going on forever, meaning its irrational. 2.010010001... goes on forever, and the square root of 6 also goes on forever.

-51/5, however, does not go on forever. The square root of 64 is 8, so these two are rational.

Sampling bias

Step-by-step explanation:

Sampling bias is due to the mistaken manner of selection of the respondents for the survey when conducting market research or similar survey. The sampling bias error is said to have occurred when the sample selection procedure, methodology, or process focuses on part of the population with a particular attribute, rather than being a random sample. Such that a given subset of the of the population are selected for the survey, which results in a biased sample.
