Answer:

Answer D:  (-2, 1):  maximum

Step-by-step explanation:

This graph is that of a parabola that opens down.  The graph clearly has a maximum.  

That max is at x = -2 and y = 1:  (-2, 1) (Answer D).

Make a Matlab script to make row 2 of matrix A equal to first row of A multiplied by the negative of the first element of row 2
stira [4]

Answer:

X=\begin{Bmatrix}2& 1 &10 \\-3 & 5 & 4\end{Bmatrix}

Step-by-step explanation:

From the question we are told that

Matrix is given as A=\begin{Bmatrix}2 & -1 & 10\\-3 & 8 & 4\end{Bmatrix}

Generally let the change in matrix be given as X

X_1_2 = 2*(-(-1)) + - 1 = 1X_2_2 = -3 * (-(-1))+ 8 = 5

Matlab output

A=[2 -1 10;-3 8 4]\\a=(A(1,1)*-A(1,2))+A(1,2)\\b=(A(2,1)*-A(1,2))+A(2,2)\\X=[A(1,1) a A(1,3); A(2,1) b A(2,3)]\\

Generally the matrix that makes row 2 of matrix A equal to first row of A multiplied by the negative of the first element of row 2 plus the original row is

X=\begin{Bmatrix}2& 1 &10 \\-3 & 5 & 4\end{Bmatrix}

In triangle PQR, Line QS and line SR are angle bisectors to angle P (74 degrees). How many Degrees are in the angle QSR.
AlexFokin [52]

we know that

<u>in the triangle PQR</u>

m∠PQR+m∠QPR+m∠QRP=180°------> the sum of the internal angles of a triangle is equal to 180 degrees

(m∠PQR+m∠QRP)+74°=180°-------> (m∠PQR+m∠QRP)=106°

we know that

If QS and SR are angle bisectors

then

<u>In the triangle QSR</u>

m∠SQR+m∠QSR+m∠QRS=180°-------> equation 1

and

(m∠SQR+m∠QRS)=106°/2--------> (m∠SQR+m∠QRS)=53°

substitute the value of (m∠SQR+m∠QRS)=53° in the equation 1

53°+m∠QSR=180°

m∠QSR=180°-53°-------->m∠QSR= 27°

therefore

<u>the answer is</u>

The measure of angle QSR is  27 degrees

The talent show committee sold a total of 530 tickets in advance. Student tickets cost $3each and the adult tickets cost $4 each
Serggg [28]
Students = 380
Adults = 150

You can get this by using x = students and y = adults. Then set up a cost equation of:

3x + 4y = 1740

and a total tickets equation of 

x + y = 530

Solve using any method.

1. The population of a town was 5655 in 2010. The population grows at a rate of 1.4% annually.
slava [35]

Answer:

Step-by-step explanation:

b = 5655

r = 1.4% = 1.4/100 = 0.014

Therefore, the equation would be

y = 5655(1 + 0.014)^t

y = 5655(1.014)^t

b) in 2022, t = 2022 - 2010 = 12 years

y = 5655(1.014)^12

y = 6682

Anvisha [2.4K]

Answer:

$2.10

Step-by-step explanation:

To find the total cost, multiply.

12.25*1.20 = 14.7

Tommy and 6 of his friends means 7 people.

Cost per person will be:

14.7/7 = 2.1
