i) Draw a point at the bottom corner. From here count 7 right and 3 up. Mark this point aswell. Join these 2 point together to create a line and put an arrow head half way through to show direction.

ii) 2+5 = 7

So the column vector would be 7 over 3 in brackets

Answer:

I believe the answer is p = -7/5

Step-by-step explanation:

Here's the equation and the workthru of my logic:

-5 (p + 3/5) = -4

Divide both sides by -5 to remove the -5 from the left side of the equation,

p + 3/5 = -4/5,

Subtract 3/5 from both sides to solve for p,

p = -4/5-3/5

p = -7/5

Solution is -7/5

Hope this helps.

Why does multiplying the input of a linear function change
only the slope while multiplying the output changes both the slope and the
y-intercept?

Answers

Answer:

Step-by-step explanation:

If we have a linear function and we multiply the input of the function, we aren't really changing the values of the function, we're changing the rate at which those values are reached.

E.g. if you look at the attached picture, we have [tex]f(x) = 2x[/tex] and [tex]f_2(x) = 4x[/tex], which is just [tex]f(2x)[/tex]. The value when the red line is x = 1 is half that of the value of the blue line when x = 1.

The values of the f(2x) line are reaching the values of f(x) twice as fast, meaning it has a slope of twice as much. However, it still grows through the same intercept.

If you're interested in the calculus behind this, look up the chain rule of derivatives.

However, when you start changing the output of the function, you're changing the entire equation. It's not the same line anymore.

The altitude of an isosceles triangle bisects the base and measures 10ft. If the base of the triangle measures 16ft, calculate: a) the area of the triangle b) and one side of the triangle.

Answers

Answer:

Step-by-step explanation:

the formula for calxulating the area if the isosceles triangle is expressed as;

[tex]A = \frac{1}{2}bh[/tex]

b is the base of the triangle

h is the altitude

Given

b = 16ft

h = 10ft

Substitute

A = 1/2 * 16 * 10

A = 8*10

A = 80ft²

Hence the area of the triangle is 80ft²

b) To get the measure of one side of the triangle, we will use the pythagoras theorem. Let s be the slant side

s² = h²+(b/2)²

s² = 10²+(16/2)²

s² = 10²+(8)²

s² =100+64

s² =164

s = √164

s = 12.8ft

Hence one side of the triangle is 12.8ft

Mira has breakfast at a restaurant. She leaves a 20\%20%20, percent tip of \$1.80$1.80dollar

Answers

Answer:

Price of Mira Breakfast = 9 $ before tip

Step-by-step explanation:

Let say Mira's breakfast Price = B $

Tip she left = 20 %

20 % Tip amount =  (20/100) B =  0.2B $

Tip Amount She left = $ 1.8

Equating Tip Amount

0.2B = 1.8

Find the equation of a line that passes through the points (6,7) and (8,3).
Leave your answer in the form
y = mx + c

Answers

Answer:

y=-2x+19

Step-by-step explanation:

For lines like these, the slope is always defined as "the change in y over the change in x" or, in equation form:  m= [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex].

Now we have,

m= 3-7/8-6

m=-2. Since m=-2, the equation is y=-2x+b.

To find b, think about what your (x,y) points mean:

(6,7). When x of the line is 6, y of the line must be 7.

(8,3). When x of the line is 8, y of the line must be 3.

Substitute them to the equation  y=-2x+b.

You can use either (x,y) point you want..the answer will be the same:

(6,7). y=mx+b or 7=-2 × 6+b, or solving for b: b=7-(-2)(6). b=19.

(8,3). y=mx+b or 3=-2 × 8+b, or solving for b: b=3-(-2)(8). b=19.

So, the equation of the line that passes through the points

(6,7) and (8,3)  is  y=-2x+19.

In vesicular transport, __________ transport materials into and out of the cell using _______. Select the correct text in the passage.Read this excerpt adapted from A Brave Lad. This story originally appeared in Chatterbox, a book of stories edited by J. Erskine Clarke.Which line from the story supports the idea that Fred is a courageous boy?It was Saturday afternoon when the boys of Wedderburn School went off as usual to swim their boats on a beautiful lake. Fred Langton had a new boat, which his grandfather had sent to him as a birthday present. It was a larger and better-constructed boat than any of the others. Each boy was, of course, eager that his own boat should win the race. Although all the boys admired Fred's boat and wished that they could have had one as good, they felt no grudge towards Fred himself. In fact, he was a general favorite in the school. He was kind-hearted, unselfish, and always willing to give anything that he had to his companions.I tell you, said Bill Cowan to his own particular chum, Joe Morris, that boat of Fred's will beat ours all hollow! I wish I had one as good!Well, suppose it does win, replied Joe Morris, I shall not grudge it to him, for Fred is no sneak; he is out-and-out the jolliest fellow in Wedderburn School.So he is, said Bill Cowan, and no mistake about it. Well, here we are at the lake, and now for some fun.On this particular Saturday, however, Fred was going to become famous in quite another way. The little boats were all in full sail, and the schoolboys were shouting with glee at the fun. Suddenly a fox-terrier took it into his head to chase the boats and show that he could swim as well as they could. Poor dog! It was quite true that he could swim. Unfortunately he got caught among weeds. He began struggling in the water and barking for help.Oh, I say, I can't stand this! cried Fred Langton; he will be drowned. I must go in and fetch him out!No, no! cried Bill Cowan; the lake is quite deep just at that place.Yes, I know it's deep, added Joe Morris, and, besides, you can't swim, Fred; don't be silly. Who cares for a dog being drowned?I do, for one, cried Fred, and dashing into the water he waded out to where the poor dog was half-standing, half-lying, among the choking weeds. Yes, the water was deep; but stretching out his arms he contrived to catch hold of the poor animal, and he quickly waded back to shore amid ringing cheers from all the people who had now gathered on the bank to watch the plucky lad. And whose was the dog? Nobody knew; it seemed, indeed, to have no owner and no home. But Fred and his companions carried it back with them to the school, and, after having told their tale, they begged the head master to keep it for himself. As Dr. Williams could not discover anything about the dog's ownership, he did keep it. So Fred's brave deed not only saved the animal's life, but procured a good home for it as well.
