The discriminant if a quadratic equation is negative. One solution is 4 + 7i. What is the other solution? *
7 - 4i
4 - 7i
- 4 + 7i
7 + 4i
==========================================================
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.

find the eaxct value of b.
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

A right prism has a volume of 65 cubic inches. The prism is enlarged so its height is increased by a factor of 20, but the other dimensions do not change. What is the new volume? A.1000 in .3 B.1300 in .3 C.1200 in. 3 D. 1100 in.3
Answer:
Volume of a right prism = 65 cubic inches
Its height is increased by a factor of 20.
To find:
The new volume of the prism if the other dimensions do not change.
Solution:
The volume of a prism is:
[tex]Volume=Bh[/tex]
Where, B is the base area and h is the height.
A right prism has a volume of 65 cubic inches.
[tex]65=Bh[/tex]
The height of prism is increased by a factor of 20. So, the new volume is:
[tex]Volume=B(20h)[/tex]
[tex]Volume=20(Bh)[/tex]
[tex]Volume=20(65)[/tex]
[tex]Volume=1300[/tex]
The volume of the new prism is 1300 in³.
Therefore, the correct option is B.

If 30 buses can carry 1,500 people, how many people can 5 buses carry? A 200 © 500 B 250 D 750
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.

Question 7: The ratio of M's to A's cat is 5:7. Meg's cat weighs 20 kg. How
much more does Anne's cat weigh?
A) 28 kg
B) 2 kg
C) 8 kg
D) 9.3 kg
Answer: C
Step-by-step explanation: The ratio shows that Anne's cat is 2kg heavier, but Meg's cat weighs 20kg which is 4 times what the ratio shows the weight is, so the difference of the weight is also 4 times greater, which is 8kg!
The value of weight of Anne's cat will be 28 kg. Then the correct option is A.
What is the ratio?The utilization of two or more additional numbers that compares is known as the ratio.
The definition of simplicity is making something simpler to achieve or grasp while also making it a little less difficult.
The ratio of M's to A's cat is 5:7. Meg's cat weighs 20 kg.
Let 'x' be the weight of Anne's cat. Then the equation is given as,
5 / 7 = 20 / x
Simplify the equation, then we have
5 / 7 = 20 / x
1 / 7 = 4 / x
x = 28 kg
The value of weight of Anne's cat will be 28 kg. Then the correct option is A.

Answer:
Slope= 2 ; y intercept= 4
Step-by-step explanation:
Slope: (y2 - y1)/(x2-x1) where x and y indicate the coordinates of two points
Slope = (4-0)/(0-(-2) = 4/2 = 2
y intercept is where the line intercepts the y axis: it happens in (0;4)
Answer:

Answers to questions A and B
Answer:
A. m(arc BC) = 16°
B. m(arc BAC) = 344°
Step-by-step explanation:
From the picture attached,
AB is the diameter of the circle.
Since, measure of an arc is always same as the central angle of arc.
Therefore, m(arc AC) = m(∠ADC) = 164°
m(arc AB) = 180°
m(arc BC) = 360° - m(arc AB) + m(arc AC)
= 360° - (180° + 164°)
= 360° - 344°
= 16°
m(arc BAC) = m(arc AB) + m(arc AC)
= 180° + 164°
= 344°
Round the number 74.054 to the nearest tenth
Answer:
74.054 rounded to the nearest tenth is equivalent to 74.1
Step-by-step explanation:
Since you're rounding 74.054 to the nearest tenth, you need to focus on the hundredths place. If the number on the hundredths place is greater than or equal to 5, then you round up. If not, keep the number in the tenths place the same. In this case, 5 is in the hundredths place, which means you need to round the 0 in the tenths place up by 1. So 74.054 rounded to the nearest tenths is equivalent to 74.1.

Answer:
65
Step-by-step explanation:
<S = <t
x + 50 = 3x + 20
2x = 30, x = 15
. <t = <v
3x + 20 = 45 + 20 = 65
Answer:
b. 65 degrees.
Step-by-step explanation:
m < RST = m < STU (alternate angles), so
x + 50 = 3x + 20
50 - 20 = 3x - x
2x = 30
x = 15.
Now m < RVT = m < RST ( opposite sides of a parallelogram are equal).
So m < RVT = x + 50 = 15 + 50 = 65.
