Answer:

\overrightarrow{AB }=\begin{bmatrix}-4\\3 \end{bmatrix}

Step-by-step explanation:

<u>Column Vector</u>

Vectors are matrices having only one column or one row. A vector having only one column is called a column vector, and a vector having only one row is called a row vector.

It's required to find the vector AB as a column vector, and we are given the coordinates of A=(6,4) and B=(2,7).

The vector directed from A to B is found by subtracting its corresponding coordinates:

\overrightarrow{AB }=

\overrightarrow{AB }=

Now we express the vector as a one-column matrix as follows:

\overrightarrow{AB }=\begin{bmatrix}-4\\3 \end{bmatrix}

In the figure below, BD and EC are diameters of circle P. What is the arc measure of ADE in degrees? IMAGE BELOW
Pani-rosa [81]

Answer:

The arc measure of ∠ADE is equal to 333 degrees.

Step-by-step explanation:

Please refer to the attached diagram,

Let the unknown angle ∠APE = x

Since BD is the diameter of the circle then

∠APE + ∠DPE + ∠APB = 180°

∠APE + 63° + 90° = 180°

x + 63° + 90° = 180°

Solving for x

x = 180° - 90° - 63°

x = 90° - 63°

x = 27°

Since a circle has 360° then

∠ADE + ∠APE = 360°

∠ADE + x = 360°

∠ADE + 27° = 360°

∠ADE = 360° - 27°

∠ADE = 333°

Therefore, the arc measure of ∠ADE is equal to 333 degrees.

Which system of equations is represented by the graph?
Arlecino [84]

Answer: C

Step-by-step explanation:

y = mx + b

To get ‘b’ look at the y intercepts.

Both y intercepts are 7 and - 1

For this problem it’s all you need, since the only equations with b being - 1 and 7 is C.

Priya has picked 1 1/2 cups of raspberries which is enough for 3/4 of the cake how many cups does she need for the whole cake
Zina [86]

Answer:

So Priya need  2 cups of raspberries for the whole cake.

Step-by-step explanation:

Given data;

1\frac{1}{2}=\frac{3}{2} cups of raspberries which is enough for \frac{3}{4} of the cake.

For making \frac{3}{4} of the cake need \frac{3}{2} cups of raspberries.

For making 1 cake need \frac{\frac{3}{2}}{\frac{3}{4}} cups of raspberries.

For making 1 cake need \frac{3}{2} \times \frac{4}{3}=2 cups of raspberries.

∴ Priya need  2 cups of raspberries for the whole cake.
