Line Segment BC has endpoints B (3,5) and C (7,15). Find the missing coordinates of A (x,9) and D (17,y) such that AB and CD are

o-na [289]

Answer:

x=-7

y=11

Step-by-step explanation:

Perpendicular Vectors

Two vectors defined as their endpoints $\vec u=$ and $\vec v=$ are perpendicular if their dot product a.b is zero. The dot product is

$\vec u.\vec v=ac+bd$

In other words

ac+bd=0

Let's treat all the points as the extremes of vectors, so we can easily find the missing coordinates

B (3,5) and C (7,15) define a segment, the vector

$\overrightarrow{BC}==$

The point A is A (x,9), we need to form a vector with B

$\overrightarrow{AB}==$

this vector must be perpendicular to BC, so, applying the dot product we have

$4(x-3)+40=0$

$4x-12=-40$

$x=-7$

The point D is D(17,y), we need to form a vector with C

$\overrightarrow{CD}==$

this vector must be perpendicular to BC, so, applying the dot product we have

$(4)(10)+(10)(y-15)=0$

$40+10y-150=0$

$10y=110$

$y=11$

The points are

$\boxed{A(-7,9), D(17,11)}$

Analyze each situation. Identify a reasonable domain and range for each situation. Explain.

Dahasolnce [82]

Answer: A The domain is all positive integers, because the bowler could not play a fractional or negative number of games.

The range is multiples of 2.75.

B The domain is all positive real numbers, since a portion of a gallon of gas could be used.

The range is all positive real numbers.

You need 3 1/2 cups of flour for each batch of cupcakes. How many whole batches can make if you have 17 cups of flour? Show two

rosijanka [135]

ANSWER:

4 batches of cupcakes can be made.

SOLUTION:

Given, we need $3\frac{1}{2}$ cups of flour for each batch of cupcakes. And we have 17 cups of flour.

We need to find how many batches can be made.

1st way:

We will get the number of batches when we divide the available cups with cups required for one batch.

Available cups = 17 and required cups for one batch = $3\frac{1}{2}$ = $\frac{7}{2}$ cups

number of batches = $\frac{17}{\frac{7}{2}}$

$=\frac{17}{1} \times \frac{2}{7}$

$=\frac{34}{7}$ = 4.857

As the number of batches can’t be fraction, we will neglect the fractional part.

2nd way:

Let the number of batches be x.

Then, cups of flour required for batches must be less than available flour

(x)( $\frac{7}{2}$ ) < 17

(x)(7) < (2)(17)

7x < 34

x < $\frac{34}{7}$

x < 4.857

As the number of batches must be an whole number, x becomes 4.

Hence, 4 batches of cupcakes can be made.
