If represented in a stem and leaf plot, what would be the leaf of the number 329?​
sdas [7]

Answer:

You can either do a back to back stem and leaf plot, where you would have double the values. In a normal stem and leaf plot you would just have one set of 3's where you would put all the values that start with 3 in that column. A back to back is the same but instead you would have two 3 values, where anything that is higher than 5 would be in the second value of 3, but anything lower would be in that first value of 3.

General form of the equation of a circle with its center at (-2, 1) and passing through (-4, 1)
jonny [76]

 

hello :<span>
<span>an equation of the circle Center at the A(a,b) and ridus : r is :
(x-a)² +(y-b)² = r²
in this exercice : a = -2 and b = 1 (Center at the A(-2,1))
r = AP......P( -4 , 1)
r² = (AP)²
r² = (4+2)² +(1-1)² = 36
an equation of the circle that satisfies the stated conditions.
Center at </span></span> A(-2,1), passing through P(-4, 1) is : (x+2)² +(y-1)² = 36

What is 2A?<br> A= [4 9 13 5]
Ierofanga [76]

Answer:

Multiply each entry by 2!

Step-by-step explanation:

Multiplying a matrix by a constant means to multiply each entry by that constant.

According to that, 2A would be the result of each entry being multiplied by 2.

That is equal to $ 2A = \begin{pmatrix}2(4) & 2(9) \\2(13) & 2(5) \\\end{pmatrix}

$ \implies 2A = \begin{pmatrix}8 & 18 \\26 & 10 \\\end{pmatrix}

Hence, the answer.
