3. Explain why (x – 4)2 = -9 has no real solutions.

Answers

Answer:

an equation is said to have no real solutions when value of x < 0

Step-by-step explanation:

here,

(x-4) 2= -9

2x - 8 = -9

2x = -1

x = -1/2

which is less than 0

The equation (x – 4)² = -9 has no real roots.

What is the solution of a quadratic equation?

The solution of a quadratic equation is the value of the variable for which the expression becomes true.

Given,

          (x – 4)² = -9

The LHS of the equation is either positive or zero.

But, the RHS of the equation is a negative value.

Therefore, RHS and LHS can never be equal.

Hence, the equation (x – 4)² = -9 has no real roots.

Find the 40th term 360,353,346,...

Answers

Answer:

87

Step-by-step explanation:

First method:

- Open Excel and enter 360, 353 and 346 in column A (below each other)

- Select all 3 cells and drag the bottom-right square down to row 40.

Second method:

- Use the equation t(n) = 360-7(n-1)

- Solve for n=40

- t(40) = 360 - 7*39 = 87

I dont understand this question, i did the factor of 36x^2 - 49 but I dont understand the second part

Step-by-step explanation:

Since both 36 and 49 are perfect squares, you can find their square roots which are 6 and 7.

To check to see if it is correct, replace the a with 6 and replace the b with 7, then evaluate the exponents.

Consider the work sample and statements below. Select ALL that apply.

Geometric shapes are mathematical shapes that include squares and triangles

How to prove the shape is a square

The side lengths of a square are congruent, and the adjacent sides are perpendicular.

So, we start by calculating the side lengths using the following distance formula

[tex]d = \sqrt{(x_1 -x_2)^2 + (y_1 -y_2)^2}[/tex]

Using the above formula, we have:

[tex]AB = \sqrt{(3-2)^2 + (4+2)^2} = \sqrt{37[/tex]

[tex]BC = \sqrt{(2+4)^2 + (-2+1)^2} = \sqrt{37[/tex]

[tex]CD = \sqrt{(-4+3)^2 + (-1-5)^2} = \sqrt{37}[/tex]

[tex]DA = \sqrt{(-3-3)^2 + (5-4)^2} = \sqrt{37}[/tex]

The above shows that the side lengths of the square are congruent.

Next, calculate the slope of the sides using:

[tex]m = \frac{y_2 -y_1}{x_2 -x_1}[/tex]

So, we have:

[tex]m_{AB} = \frac{4 +2}{3 -2} = 6[/tex]

[tex]m_{BC} = \frac{-2 + 1}{2+4} = -\frac 16[/tex]

[tex]m_{CD} = \frac{-1 -5}{-4+3} = 6[/tex]

[tex]m_{DA} = \frac{5 -4}{-3-3} = -\frac 16[/tex]

Notice that the opposite slopes are congruent, and the adjacent slopes are opposite reciprocal.

The above highlight, and the equal side lengths show that the figure (1) is a square

How to prove the shape is a right isosceles triangle

The legs of a right isosceles triangle are congruent, and the legs are perpendicular.

So, we start by calculating the lengths of the legs using the following distance formula

[tex]d = \sqrt{(x_1 -x_2)^2 + (y_1 -y_2)^2}[/tex]

Using the above formula, we have:

[tex]XY = \sqrt{(5-4)^2 + (-1-4)^2} = \sqrt{26[/tex]

[tex]XZ = \sqrt{(5-0)^2 + (-1+2)^2} = \sqrt{26[/tex]

The above shows that the legs of the right isosceles triangle are congruent.

Next, calculate the slope of the legs using:

[tex]m = \frac{y_2 -y_1}{x_2 -x_1}[/tex]

So, we have:

[tex]m_{XY} = \frac{5-4}{-1 -4} = -\frac{1}{5}[/tex]

[tex]m_{XZ} = \frac{5-0}{-1+2} = 5[/tex]

Notice that the slopes are opposite reciprocal.

The above highlight, and the equal legs show that the figure (2) is a right isosceles triangle

The radius of the wheel is 11 inches. What is the diameter of the wheel?

Answers

Answer:

22 inches

Step-by-step explanation:

Diameter = 2*radius = 2(11) = 22 inches

11x2=22 so 22 is the diameter of 11

two friends share 1/2 of a pizza equally. What fraction of the pizza does each friend get?

Answers

Answer:

1/4

Step-by-step explanation:

In this equation, from the beginning we know two things, that there are two people, and that the whole is 1/2

So we just have to divide! Use this equation whenever dealing with word problems like these and you’re stuck.

Amount of object (Pizza Size) divided by Number of Groups (People) = Amount of object in group

So our equation is 1/2 divided by 2

Calculate this and we will get our final answer of

1/4!

Answer:

Distributive Property

Step-by-step explanation:

If you multiply first,

6(2 + .03)

6•2 + 6•.03

You must multiply the 6 times BOTH of the terms inside the parenthesis.

This is using the Distributive Property.

PLS HELP!! (40PTS.) (PRE-CALCULUS)

Answers

Step-by-step explanation:

All of these vectors are in DE Moviere Form, so let put them in Vector notation

To this this, multiply the modulus by the exact values of trig functions,

So using this, Vector u

[tex]u= 3j + 3 \sqrt{3} i[/tex]

Vector V

[tex]v = 2 \sqrt{2} j - 2 \sqrt{2} i[/tex]

Vector W

[tex]w = - 6 \sqrt{3}j + 6i[/tex]

So know we can compete the parts.

For Part A:

We first multiply the vector U by -7 then multiply that by v.

[tex] - 7u = - 21j - 21 \sqrt{3} j[/tex]

Know we do cross product

[tex] - 7u(v) = ( - 21j - 21 \sqrt{3} i)(2 \sqrt{2} j \: + 2 \sqrt{2} i[/tex]

First, multiply the j componets.

Then, do the I componets and then add the product together.

[tex] - 42 \sqrt{2} j - 42 \sqrt{6} i[/tex]

So the answer to part A is the vector above.

Part B:

Let first find the dot product of u and w.

First, the cross product of u and w is

[tex] - 18 \sqrt{3} j + 18\sqrt{3} i[/tex]

The magnitudes of each respective vector is

6 and -12. So if we use dot product formula

[tex] \cos( \alpha ) = \frac{xy}{ |x| |y| } [/tex]

So we get

[tex] \cos( \alpha ) = \frac{ - 18 \sqrt{3} + 18 \sqrt{3} }{ - 72} [/tex]

[tex] \cos(a) = \frac{0}{ - 12} [/tex]

[tex] \cos(a) = 0[/tex]

[tex]a = \frac{\pi}{2} [/tex]

Since the angle is pi/2, the vectors are orthogonal.

Find the equation of the line having a slope of 4 and a y-intercept on (0,3)

Answers

[tex]\mathbb{FINAL\:ANSWER:}[/tex]

[tex]\huge\boxed{\sf{y=4x+3}}[/tex]

[tex]\mathbb{SOLUTION\:WITH\:STEPS:}[/tex]

Hi! Hope you are having a nice day!

We are given the slope of the line and its y-intercept.

So, let's find the equation.

The y-intercept is written in the form (0, b).

No worries! b is the y-intercept.

Thus, the y-intercept equals 3.

Now, let's find the equation of the line with a slope of 4 and a y-intercept of 3.

We can write the equation in Slope-intercept form:

y=mx+b, where m stands for the slope and b stands for the y-intercept.

Since we have both m and b, we can just plug the given values:

y=4x+3 ✓

Hope you could understand everything.

A cylindrical vase has a diameter of 6 inches. At the bottom of the vase, there are 7 marbles, each of diameter 3 inches. The vase is filled with water up to a height of 12 inches. Which of the following could be used to calculate the volume of water in the vase?
π(12in)2(3in) − 7(four over threeπ(1.5in)3)
π(3in)2(12in) − 7(four over threeπ(1.5in)3)
π(12in)2(3in) − 1.5(four over threeπ(7in)3)
π(3in)2(12in) − 1.5(four over threeπ(7in)3)

Answers

Answer:

Step-by-step explanation:

Vase:

h = 12 in

r = diameter/2 = 6/2 = 3 in

Volume of vase = πr²h

                            = π(3)²*12

Marbles:

r = 3/2 = 1.5 in

[tex]Volume \ of \ marbles = \dfrac{4}{3}\pi r^{3}\\\\\\Volume \ of \ 7 marbles=7*\dfrac{4}{3}\pi (1.5)^{3}[/tex]

Volume of water = Volume of vase - volume of 7 marbles

                            [tex]= \pi (3)^{2}*12 - 7*\dfrac{4}{3}\pi (1.5)^{3}[/tex]

Answer:

second choice

Step-by-step explanation:

the volume of water in the vase

= volume of the vase up to the height 12 inches - volume of 7 marbles

= π(6/2)²(12) - 7(4/3)π(3/2)³

so answer is the second choice
