Write a quadratic function f whose only zero is 7

Mathematics
1 answer:
Snezhnost [94]3 years ago
5 0

well, we know is a quadratic, namely of degree 2, so it has two solutions and namely two factors, and whose only zero is 7, well, we can do that by giving that only zero a multiplicity of 2, so we get two of the same zero.

\begin{cases} x=7\implies &x-7=0\\ x=7\implies &x-7=0 \end{cases}\qquad \implies \qquad \begin{array}{llll} \stackrel{\textit{multiplicity of 2}}{(x-7)(x-7)}=\stackrel{0}{y} \\\\\\ x^2-14x+49=y \end{array}

1. A family is building a circular fountain in the backyard. The yard is rectangular and measures 10x by 15x and the fountain is
sp2606 [1]
1. The remaing area of the yard will be found as follows:
Area of the yard

A1=length*width=10x*15x=150x^2 yd^2

area of the fountain
A2=πr²
A2=π(4x)²
=50.266x^2

The remaining area will be:
A=150x^2-50.266x^2
A=99.735x^2 yd^2


2] Area left for bleachers, restrooms and other parts of the stadium will be as follows:
Area of the lot is:
A1=length*width
A1=8x×12x= 96x^2 

Area of the field
A2=length×width
A2=3x×6x=18x^2

Hence the remaining area will be:
A1-A2
=96x^2-18x^2
=78x^2 sq. units

I need help finishing RT. Please help. I do not know what to do. Any help will be appreciated:))
Advocard [28]

Answer:

RT = 86

Step-by-step explanation:

Here, we want to find the value of RT

looking at the given triangle, we can deduce that the smaller triangle SPQ is half the measure of the bigger triangle SRT

what this mean is that we have to multiply the dimensions on SPQ by 2 to get the equivalent dimensions of similar sides in SRT

Thus, we have it that;

2(15x -17) = 23x -6

30x - 34 = 23x -6

30x -23x = -6 + 34

7x = 28

x = 28/7

x = 4

So, we make a substitution

for RT;

23x-6

= 23(4) - 6 = 92-6 = 86

Ugo [173]
Your answer is going to be D.
In order to find P, you would divide $10.25 by 50, which means the 50p is $10.50.

I WILL GIVE BRAINLIEST Which of the following tables of x– and y–values represents a function? Select all that apply.
Otrada [13]

Answer:

A and C

Step-by-step explanation:

For a table of x and y variables to be a function, each x-value must not have two different y-values assigned or related to it. However, different x-values can have the same y-value.

Therefore, the table in option A and option C are functions because every of their x-value has exactly one y-value that corresponds it.
