what are the zeros of the expression (x-5)(2x+7)
The zeroes of the expression are 5 and -3.5.
What is an Expression?In mathematics, an expression is defined as a set of numbers, variables, and mathematical operations formed according to rules dependent on the context.
The zeroes of the expression can be found by equating the factors of the given expression with 0. Therefore, the zeroes of the expression are,
x - 5 = 0
x = 5
2x + 7 = 0
2x = -7
x = -7/2
x = -3.5
Hence, the zeroes of the expression are 5 and -3.5.

Find (f g)(x)

g(x)= 3 - 12x
find f(x) • g(x)
please, it’s for tomorrow and i need whit the process
a) for given functions f(x) = 8x and g(x) = 12x + 3,
(f g)(x) = 96x² + 24x
b) for functions f(x)= 14 and g(x)= 3 - 12x,
f(x) • g(x) = 42 - 168x
In this question, we have been given two functions.
We need to find the given function.
a) f(x) = 8x and g(x) = 12x + 3
To find (f g)(x)
We know that, the product of functions f(x) and g(x) is:
(f g)(x) = f(x) . g(x)
(f g)(x) = (8x) (12x + 3)
(f g)(x) = 96x² + 24x
So, for given functions f(x) = 8x and g(x) = 12x + 3,
(f g)(x) = 96x² + 24x
b) f(x)= 14 and g(x)= 3 - 12x
To find f(x) • g(x)
f(x) • g(x) = (14) . (3 - 12x)
f(x) • g(x) = 42 - 168x
So, for functions f(x)= 14 and g(x)= 3 - 12x,
f(x) • g(x) = 42 - 168x
Therefore, a) for given functions f(x) = 8x and g(x) = 12x + 3,
(f g)(x) = 96x² + 24x

Find domain and range
The function of domain is X∈R and the range is [tex]\[\left\{ {f \in \mathbb{R}:f \le \frac{1}{4}(1 + 4\sqrt 2 )} \right\}\].[/tex]
The given function is [tex]\[f\left( x \right) = \sqrt {2 - x - {x^2}} \][/tex]
Domain: The domain of a function is the set of input or argument values for which the function is real.
Use commutative properties to reorder the terms
[tex]\[f(x) = \sqrt { - x + 2} - {x^2}\][/tex]
Separate the function into parts to determine the domain of each part
[tex]\[f\left( x \right) = \sqrt { - x + 2} \]=-x+2= x^{2}[/tex]
Domain is XR (all real numbers)
The function has no undefined points nor domain constraints. Therefore, the domain is X∈R.
Range: The set of values of the dependent variable for which a function is defined
Range of [tex]\[\left\{ {f \in \mathbb{R}:f \le \frac{1}{4}(1 + 4\sqrt 2 )} \right\}\][/tex]
Combine the ranges of all domain intervals to obtain the function range.
Hence, the domain and the range of the function [tex]\[f\left( x \right) = \sqrt {2 - x - {x^2}} \][/tex] are

statistically speaking, the value that describes how far off an average could be is called the error.
The accuracy of a survey estimate refers to the closeness of the estimate to the true population value. Where there is a discrepancy between the value of the survey estimate and the true population value, the difference between the two is referred to as the error of the survey estimate.
The total error of the survey estimate results from the two types of error:
sampling error, which arises when only a part of the population is used to represent the whole population; and
the non-sampling error which can occur at any stage of a sample survey and can also occur with censuses. Sampling error can be measured mathematically whereas measuring non-sampling error can be difficult.
Sampling error is affected by a number of factors including sample size, sample design, the sampling fraction, and the variability within the population. In general, larger sample sizes decrease the sampling error, however, this decrease is not directly proportional.
The most commonly used measure of sampling error is called the standard error (SE). The standard error is a measure of the spread of estimates around the "true value". In practice, only one estimate is available, so the standard error can not be calculated directly.

Harry is saving for the deposit for an apartment. He has 21 350 EUR, but needs at least 30

He compares banks that offer annual interest compounded monthly.
What is the minimum interest rate he requires to meet his needs? Give your answer to three
significant figures.
[Answer format: 00.0%]
We need to know about the concept of compound interest to solve the given problem. The minimum interest rate that Harry needs to meet his need is 11.4%
Compound interest can be described as the interest that you earn on both the principal amount and the interest earned. In this question it is said that the bank offers annual interest compounded monthly, we will be using a formula to solve this problem. Since Harry has 21350 EUR we will take that as the principal amount and the minimum amount that he needs is 30000 EUR we will consider this to be the final amount at the end of 3 years. We need to find out the rate of interest that the bank offers.
A=P[tex](1+\frac{r}{12} )^{12t}[/tex] where A is amount, P is principal, r is the rate of interest and t is time period.
P=21350 EUR
A=30000 EUR
t=3
30000=21350[tex](1+\frac{r}{12}) ^{36}[/tex]
[tex]\frac{600}{427} =(1+\frac{r}{12}) ^{36}[/tex]
1+[tex]\frac{r}{12}[/tex]=1.00949
r/12=0.00949
r=0.1139
r=11.4%
Therefore we found that the minimum rate of interest Harry requires to meet his needs is 11.4%

Write an inequality for the graph.
The inequality for the graph is given by y > | x - 5 | + 1 .
An inequality in mathematics is a relation that compares two numbers or other mathematical expressions in an unequal way.
A graphical representation of an inequality in 2 dimension refers to as the region above or below the graph.
Given the graph of an inequality we write the required inequality using translation properties of a graph.
The parent function of the graph can be written as y > | x |.
the graph of y > | x | is attached below.
The following steps are used to write the inequality:
Now for the vertical shift of 1 unit of the graph we replace the y value with y-1. Therefore the new inequality becomes y-1> |x| or , y = | x | +1Now for the horizontal shift of 5 units of the graph we replace the x with x-5 , Therefore the graph becomes y > | x - 5 | + 1Hence the required inequality for the graph is given by y > | x - 5 | + 1

the set of differentiable real-valued functions f on the interval .0; 3/ such that f 0 .2/ d b is a subspace of r.0;3/ if and only if b d 0.
The condition [tex]f^{\prime}(2)[/tex] = 0 to form a subspace of [tex]\mathbb{R}^{(0,3)}[/tex] is that f ∈ S is that otherwise, S wouldn't be closed under addition and thus would not be a subspace of [tex]\mathbb{R}^{(0,3)}[/tex].
What is additive identity?An identity element (like 0 in the collective of whole numbers under operation of addition) that leaves unaffected any element that it is added in a provided mathematical system.
Now, for the given question.
I'd just like to comment on the paragraph about intuition as well as the additive identity: That instinct is incorrect.
First, we could perhaps define a object that we need to confirm is a subspace of [tex]\mathbb{R}^{(0,3)}[/tex] in a more precise manner than the translation in which it is initially presented. We want to look at a set, S.
Where,
[tex]S=\left\{x, f \mid 0 < x < 3, f \in \mathbb{R}^{(0,3)} \wedge f^{\prime}(x)=0\right\}[/tex]
We are specifically tasked with having to prove the restriction just on derivative of f, which is best accomplished in the manner made reference.
The fact that S, as described above, describes a functional space explains why my initial intuition about problem is ultimately incorrect. I was hindering myself by viewing it solely as a geometric space.
As a result, I missed the fact that zero function (the additive identity in such a functional space) is indeed a natural member of S.

TRUE OF FALSE. A dilation with a scale factor that is not equal to 1 is always used to create
similar figures while it is never used to create congruent figures.
Answer:
False! as long as the the Scale Factor is 1, there is still a possibility that the figure will be congruent or greater! GOOD LUCK!
Answer: True
Step-by-step explanation: This is the difference between using transformations to create similar figures vs using transformations to create congruent figures. Similar figures are figures with the same shape. Congruent figures are figures with the same shape and size. If the scale factor is not equal to 1, then the figures are similar. If the scale factor is equal to 1, then the figures are congruent.
