Find the y-intercept for the parabola defined by

Maurinko [17]

Answer:

11cm

Step-by-step explanation:

Hi, I can help.

Now to find this it is just simple subtraction but you need to know what to look for.

Let us first imagine that the top rectangle sticking out doesn't exist. Lets focus on the bottom rectangle who has the dimensions of 6 and 18cm. We need to find the ? on the top of the rectangle.

Now lets add the top rectangle. Something important to remember is that the 5cm top lines up with the ? even though it is above it.

Also, the top and bottom of a rectangle is always to going to match up / be equal.

So the 5cm + ? is going to be equal to 16cm.

So how can we use this info to find the answer? We can actually look at the 16cm and 5cm. Since the 16cm and the 5 + ? are equal we can take the 16cm at the bottom and actually take away 5cm away from it to find the ?.

So :

16cm - 5cm = 11cm

So literally that is it.

11cm is your ?

I feel like I didn't do a great job explaining this so if you have any questions AT ALL please comment or message me and I will help you anywhere its needed. :)

baker has 5\dfrac145 4 1 5, start fraction, 1, divided by, 4, end fraction pies in her shop. She cut the pies in pieces that a

kupik [55]

Answer:

The answer is "She cut a total of 42 pieces of pie".

Step-by-step explanation:

Given :

Total pie= $5 \frac{1}{4}$

cut pie = $\frac{1}{8}$

The number of pieces of the pie she has=?

Solve the mixed fraction value:

$\to 5 \frac{1}{4}= \frac{21}{4}$

If she cuts the pieces into the entire pie, that is = $\frac{1}{8}$

So, the equation is:

$\to \frac{21}{4} = \frac{1}{8} \times x$

$\to x= \frac{21 \times 8}{4}\\\\ \to x= 21 \times 2\\\\ \to x=42$

Given f(3)=7 and f(5)=252 write the first 6 terms of the sequence. no decimals

finlep [7]

$\bf \begin{array}{|cl|ll} \cline{1-2} term&value\\ \cline{1-2} f(1)&\\ f(2)&\\ f(3)&7\\ f(4)&7r\\ f(5)&7rr\\ &252\\ \cline{1-2} \end{array}\qquad \qquad 7rr=252\implies 7r^2=252\implies r^2=\cfrac{252}{7} \\\\\\ r^2=36\implies r=\sqrt{36}\implies r=6 \\\\[-0.35em] ~\dotfill\\\\ \begin{array}{|cl|ll} \cline{1-2} term&value\\ \cline{1-2} f(1)&\stackrel{\frac{7}{6}\div 6}{\cfrac{7}{36}}\\ &\\ f(2)&\stackrel{7\div 6}{\cfrac{7}{6}}\\ &\\ f(3)&7\\ f(4)&42\\ f(5)&252\\ f(6)&1512\\ \cline{1-2} \end{array}$

notice, once we know what the common factor "r" is, from the 3rd term we can simply multiply it by "r" to get the next term, and divide the 3rd term by "r" in order to get the previous term, namely the 2nd term, and then divide the 2nd by "r" to get the 1st one.

What is the slope, m, and the y-intercept of the line that is graphed below?

Pepsi [2]

Answer:

Slope: 1

Y-intercept: (0,3)

Step-by-step explanation:

The y intercept is when the slope reaches the y-axis line. In this case, it is given to us. Anything that is formed like this: (0, y) is the y-intercept.

Y intercept: (0, 3)

For slope, you can use the formula rise over run. $\frac{Rise}{Run}$

From the picture, I have drawn the rise over run, which is $\frac{3}{3}$ , which is also 1.

Slope: 1

Hope this helped.
