Answer:

2nd graph (in the attached pics)

Step-by-step explanation:

Graphically, the <em>x-intercepts of the graph of a quadratic function are its zeroes. </em>

There can be

no zeroes (where graph doesn't cut the x-axis at all),
1 zero (where graph touches the x-axis at one point only), and
2 zeros (where the graph cuts the x-axis at 2 points)

Looking at the figures, the 2nd graph has no real zeroes, <em>because the graph doesn't cut the x-axis at all!</em>

<em />

So, the answer is the second graph.

If the cost, C(x), for manufacturing x units of a certain product is given by C(x)=x^2-14x+74, find the number of units manufact

vova2212 [387]

<h2>Steps:</h2>

So for this, since C(x) is the cost, and we are given the cost of $9050, we will plug 9050 into C(x) and solve for x:

$9050=x^2-14x+74$

So for this, I will be completing the square. Firstly, subtract 74 on both sides of the equation:

$8976=x^2-14x$

Next, we want to make the right side of the equation a perfect square. To find the constant of this soon-to-be perfect square, you need to divide the x coefficient by 2, square the quotient, then add the result on both sides of the equation. In this case:

-14 ÷ 2 = -7, (-7)² = 49

$9025=x^2-14x+49$

Next, factor the left side:

$9025=(x-7)^2$

Next, square root both sides:

$\pm\ 95=x-7$

Next, add 7 to both sides:

$7\pm 95=x$

Next, solve the left side twice. Once with the plus symbol, once with the minus symbol:

$102,-88=x$

<h2>Answer:</h2>

Since we cannot have negative units in this context, <u>at the cost of $9050 you can manufacture 102 units.</u>

Word Problem: The point (-6, 1) is on a line that has a slope of 1/3. List three other points on the line.

sergey [27]

The other points on the line are as follows:

(3, 4)(6, 5)(9, 6)

<h3>How to find the point on a line using slope?</h3>

The point (-6, 1) is on a line that has a slope of 1/3.

The equation of a line can be described as follows:

y = mx + b

m = slope
b = y-intercept

Therefore,

y = 1 / 3 x + b

(-6, 1)

Therefore,

y = 1 / 3(-6) + b

1 = -2 + b

b = 1 + 2

b = 3

Therefore,

y = 1 / 3 x + 3

when x = 3

y = 1 / 3 (3) + 3

y = 1 + 3

y = 4

(3, 4)

when x = 6

y = 1 / 3 (6) + 3

y = 2 + 3

y = 5

when x = 9

y = 1 / 3 (9) + 3

y = 3 + 3

y = 6

The other points on the line are as follows:

(3, 4)(6, 5)(9, 6)

What do you notice about your expansions for (u + v)^4 and (u + v)^5? Does your observation hold for other

ipn [44]

Answer:Yes, the observation holds for other powers of (u+v)

Step-by-step explanation:

After the binomial expansion of both functions, it is noted that the function with power of 4 contains summation of 5terms while the function with power of 5 contains summation of 6terms. This is also evident in the terms of the coefficients according to the pascal triangle. Generally, If the power of the function is 'x' then the number of terms and coefficient will be x+1.

This also holds for other powers of (u+v)
