Draw the graph of the line that is perpendicular to Y= 4X +1 and goes through the point (2, 3)
spayn [35]

Given:

\begin{gathered} y=4x+1 \\ \text{ point }(2,3) \end{gathered}

To find:

Draw a graph of a line that is perpendicular to the given line and passing through a given point.

Explanation:

As we know that relation between two slopes of perpendicular slopes of lines:

m_1.m_2=-1

Slope of given line y = 4x + 1 is:

m_2=4

So, the slope of line perpendicular to given line is:

m_2=-\frac{1}{4}

Also, so line equation that is perpendicular to given line is:

y=-\frac{1}{4}x+c...........(i)

Also, the required line is passing thorugh given point (2, 3), i.e.,

\begin{gathered} 3=-\frac{1}{4}(2)+c \\ c=3+\frac{1}{2} \\ c=\frac{7}{2} \end{gathered}

So, line equation that is perpendicular to given line is:

y=-\frac{1}{4}x+\frac{7}{2}

The required graph of line is:

Answer:

Step-by-step explanation:

\left[\begin{array}{ccc}7&31\\142&19\end{array}\right] = 7(19) - 142(31) = <em>- 4269</em>

\left[\begin{array}{ccc}7&11&21\\55&-8&2\\-16&-1&-9\end{array}\right] = 7(- 8)(- 9) + 11(2)(- 16) + 21(55)(- 1) - 21(- 8)(- 16) - 7(2)(- 1) - 11(55)(- 9) = <em>1768</em>

\left[\begin{array}{ccc}9.07&6.02&2.01\\-30.7&2.5&3.5\\3.55&-1.1&2.35\end{array}\right] = 9.07(2.5)(2.35) + 6.02(3.5)(3.55) + 2.01(- 30.7)(- 1.1) - 2.01(2.5)(3.55) - 9.07(3.5)(- 1.1) - 6.02(- 30.7)(2.35) = <em>647.3561</em>

A cube with sides numbered 1 to 6 is rolled 300 times. What is the best prediction for the number of times that a 1 or 2 would b
Leno4ka [110]
The answer is A.

Divide 300 by the number of faces of a cube.

Since there are 6 faces on a cube then we divide it.

300 ÷ 6 = 50.

So exactly 50 times.

Hope this helps :)

Willing to brainlist solve 16-17 please during this exam
ivann1987 [24]

Answer:

16. B

17. B

Step-by-step explanation:

16. The intercept form of the parabola is

y=a(x-x_1)(x-x_2),

where x_1, x_2 are two x-intercepts.

In your case,

x_1=2\\ \\x_2=-8

so

y=a(x-2)(x-(-8))\\ \\y=a(x-2)(x+8)

To find <em>a</em>, substitute coordinates of the point (-6,-4) parabola is passing through

-4=a(-6-2)(-6+8)\\ \\-4=-16a\\ \\a=\dfrac{1}{4}

and

y=\dfrac{1}{4}(x-2)(x+8)

17. The vertex form of the parabola equation is

-2p(y-k)=(x-h)^2,

where <em>(h,k)</em> are the coordinates of the vertex and sign "-" because parabola goes down.

In your case, vertex is (2,3), so

-2p(y-3)=(x-2)^2

The vertex is 3 units from the focus, then

\dfrac{p}{2}=3\\ \\p=6

The equation of the parabola is

-2\cdot 6(y-3)=(x-2)^2\\ \\y=-\dfrac{1}{12}(x-3)^2+3
