==========================================================

Explanation:

When you have a quadratic in the form ax^2 + bx + c = 0, where a,b,c are real numbers, then a negative discriminant leads to having a pair of complex roots. The roots come in conjugate pairs meaning that p+qi is one root while p-qi is the other root. The p,q are real numbers.

In the case of 4+7i being one root, we have p = 4 and q = 7, since it matches with p+qi. The other root must be 4-7i since it matches with p-qi.

In short, we flip the plus to a minus when going from 4+7i to 4-7i. All of this applies when we have a,b,c as real numbers.

If we allowed a,b,c to be complex numbers, then the roots may not necessarily come in conjugate pairs.

30 ft

Step-by-step explanation:

This situation forms a right triangle

a ² +b ²= c ²

50 ² + 40 ²= c ²

2,500 + 1,600 = c ²

900  = c ²

√900 = √c²

30 = c

Answer:

b = 19

Step-by-step explanation:

To make it short and sweet, since one angle is 45 degrees and one angle is 90 degrees, the unknown angle is 45 degrees also. That makes it an isosceles triangle with both legs equal.

b = 19

The area of the rectangle that measures 2 4/5 inches by 2 1/5 inches is: 6.16 inches².

Area of a rectangle = (length)(width).

B1=30°

Step-by-step explanation:

1. O1+O2=360°(revolution)

310°+O2=360°

O2=360°-310°

=50°

O2=2D1(centre theorem)

Answer:

x = -3

Step-by-step explanation:

4(2−4x) − 3x = 65

8 - 16x - 3x = 65

8 - 19x = 65

-19x = 65 - 8

-19x = 57

Answer:

[tex]\boxed {\boxed {\sf 250 \ people}}[/tex]

Step-by-step explanation:

Let's set up a proportion using the following setup.

[tex]\frac {buses}{people}=\frac {buses}{people}[/tex]

We know 30 buses can carry 1,500 people.

[tex]\frac {30 \ buses}{1500 \ people}=\frac {buses}{people}[/tex]

We don't know how many people 5 buses can carry, so we say 5 buses carry x people.

[tex]\frac {30 \ buses}{1500 \ people}=\frac {5 \ buses}{x \ people}[/tex]

[tex]\frac {30 }{1500 }=\frac {5 }{x }[/tex]

Cross multiply. Multiply the numerator of the first fraction by the second fraction's denominator. Then, multiply the first denominator by the second numerator.

[tex]30*x=1500*5\\30x=7500[/tex]

Solve for x. It is being multiplied by 30. The inverse of multiplication is division. Divide both sides by 30.

[tex]30x/30=7500\\x=250[/tex]

5 buses can carry 250 people.

Answer:

Area = 9(7w -1) cm²

Step-by-step explanation:

Area of a triangle is given by the expression,

Area = [tex]\frac{1}{2}(\text{Base})(\text{height})[/tex]

From the picture attached,

Base of the triangle = 18 cm

Height of the triangle = Vertical distance of the third vertex from the base joining other two vertices = (7w - 1)

Area = [tex]\frac{1}{2}(18)(7w-1)[/tex]

        = 9(7w - 1) square cm

Therefore, expression for the area of the given triangle will be,

Area = 9(7w -1) cm²

Answer:

[tex] \displaystyle V_{ \text{pyramid}}= 64 \: {cm}^{3} [/tex]

Step-by-step explanation:

we are given surface area and the length of the square base

we want to figure out the Volume

to do so

we need to figure out slant length first

recall the formula of surface area

[tex]\displaystyle A_{\text{surface}}=B+\dfrac{1}{2}\times P \times s[/tex]

where B stands for Base area

and P for Base Parimeter

so

[tex] \sf\displaystyle \: 144=(8 \times 8)+\dfrac{1}{2}\times (8 \times 4) \times s[/tex]

now we need our algebraic skills to figure out s

simplify parentheses:

[tex] \sf\displaystyle \: 64+\dfrac{1}{2}\times32\times s = 144[/tex]

reduce fraction:

[tex] \sf\displaystyle \: 64+\dfrac{1}{ \cancel{ \: 2}}\times \cancel{32} \: ^{16} \times s = 144 \\ 64 + 16 \times s = 144[/tex]

simplify multiplication:

[tex] \displaystyle \: 16s + 64 = 144[/tex]

cancel 64 from both sides;

[tex] \displaystyle \: 16s = 80[/tex]

divide both sides by 16:

[tex] \displaystyle \: \therefore \: s = 5[/tex]

now we'll use Pythagoras theorem to figure out height

according to the theorem

[tex] \displaystyle \: {h}^{2} + (\frac{l}{2} {)}^{2} = {s}^{2} [/tex]

substitute the value of l and s:

[tex] \displaystyle \: {h}^{2} + (\frac{8}{2} {)}^{2} = {5}^{2} [/tex]

simplify parentheses:

[tex] \displaystyle \: {h}^{2} + (4 {)}^{2} = {5}^{2} [/tex]

simplify squares:

[tex] \displaystyle \: {h}^{2} + 16 = 25[/tex]

cancel 16 from both sides:

[tex] \displaystyle \: {h}^{2} = 9[/tex]

square root both sides:

[tex] \displaystyle \: \therefore \: {h}^{} = 3[/tex]

recall the formula of a square pyramid

[tex]\displaystyle V_{pyramid}=\dfrac{1}{3}\times A\times h[/tex]

where A stands for Base area (l²)

substitute the value of h and l:

[tex] \sf\displaystyle V_{ \text{pyramid}}=\dfrac{1}{3}\times \{8 \times 8 \}\times 3[/tex]

simplify multiplication:

[tex] \sf\displaystyle V_{ \text{pyramid}}=\dfrac{1}{3}\times 64\times 3[/tex]

reduce fraction:

[tex] \sf\displaystyle V_{ \text{pyramid}}=\dfrac{1}{ \cancel{ 3 \: }}\times 64\times \cancel{ \: 3}[/tex]

hence,

[tex] \sf\displaystyle V_{ \text{pyramid}}= 64 \: {cm}^{3} [/tex]
