T(x)=70(.80)*+20 where x is the time in minutes and the T is the temperature in degree celsius . What is the initial temperature

Serggg [28]

Answer:

The initial temperature of the coffee was 90°C.

Step-by-step explanation:

The function representing the temperature of the coffee after x minutes is:

$T(x)=70\cdot(0.80)^{x}+20$

T is the temperature in degree Celsius.

The initial temperature of the coffee will be at x = 0.

Compute the value of T (x) at x = 0 as follows:

$T(x)=70\cdot(0.80)^{x}+20$

$T(0)=70\cdot (0.80)^{0}+20$

$=70\times 1+20\\=70+20\\=90$

Thus, the initial temperature of the coffee was 90°C.

In a certain Algebra 2 class of 21 students, 11 of them play basketball and 6 of them play baseball. There are 6 students who pl

Tema [17]

Answer:

Step-by-step explanation:

total number of students=21

students play neither sport=6

students who play at least one sport=21-6=15

Let play basketball=X

and play baseball=Y

n(XUY)=n(X)+n(Y)-n(X∩Y)

15=11+6-n(X∩Y)

n(X∩Y)=17-15=2

Question 9

Ivan

we are given two system of equations

First equation is

$y=2x-1$

we can write as

$-2x+y=-1$

Second equation is

$6x-y=13$

now, we can find augmented matrix

$A=\begin{pmatrix}-2&1&-1\\ 6&-1&13\end{pmatrix}$

now, we can change it into reduced row echelon form

step-1: multiply the 1st row by -1/2

$A=\begin{pmatrix}-1&-1/2&1/2\\ 6&-1&13\end{pmatrix}$

step-2: add -6 times the 1st row to the 2nd row

$A=\begin{pmatrix}-1&-1/2&1/2\\ 0&2&10\end{pmatrix}$

step-3:multiply the 2nd row by 1/2

$A=\begin{pmatrix}-1&-1/2&1/2\\ 0&1&5\end{pmatrix}$

step-4:add 1/2 times the 2nd row to the 1st row

$A=\begin{pmatrix}1&0&3\\ 0&1&5\end{pmatrix}$

so, we will get

$x=3,y=5$

Answer is (3,5)

The Golden Gate Bridge in San Francisco is 220 feet tall. If a model of the bridge is created with a scale of 3 feet = 80 feet,

bazaltina [42]

5866.66 feet

Step-by-step explanation:

Step 1:

Let the Golden gate bridge be 220 feet tall before using scale ratio.

Here the scale ratio given is for 3 feet = 80 feet is the scale ratio.

Step 2:

To convert the 220 feet tall gate bridge in this conversion we have to do following things.

Let 220 feet contains 73.33 × 3 feet.

For every 3 feet it is equal to 80 feet.

220 feet is approx equal to 73.33 × 80 = 5866.66 feet
