What are the roots of the equation 4x^2 + 16x + 25 = 0 in simplest a + bi form?
Answer:-2 + 3i/2, and -2-3i/2
Step-by-step explanation:
Apply the quadratic formula.
We have (-16 +-sqrt(16^2-4*4*25))/8.
Simplifying, we have (-16+-12i)/8.
Thus, the roots are -2 + 3i/2, and -2-3i/2
Answer:
The roots are
[tex]x = - 2 + \frac{3}{2} \: i \: \: \: \: or \: \: \: \: x = - 2 - \frac{3}{2} \: i \\ [/tex]Step-by-step explanation:
4x² + 16x + 25 = 0
Using the quadratic formula
That's
[tex]x = \frac{ - b\pm \sqrt{ {b}^{2} - 4ac } }{2a} [/tex]From the question
a = 4 , b = 16 , c = 25
Substitute the values into the above formula and solve
We have
[tex]x = \frac{ - 16\pm \sqrt{ {16}^{2} - 4(4)(25)} }{2(4)} \\ x = \frac{ - 16\pm \sqrt{256 - 400} }{8} \\ x = \frac{ - 16\pm \sqrt{ - 144} }{8} \\ x = \frac{ - 16\pm12 \: i}{8} \\ [/tex]Separate the real and imaginary parts
That's
[tex]x = \frac{ - 16}{8} \pm \frac{12}{8} \: i \\ x = - 2\pm \frac{3}{2} i[/tex]We have the final answer as
[tex]x = - 2 + \frac{3}{2} \: i \: \: \: \: or \: \: \: \: x = - 2 - \frac{3}{2} \: i \\ [/tex]Hope this helps you
Ashley rolls a die, flips a corner, and then roll the die again. What is the probability that he will roll to our numbers And that the coin will land on heads?
Answer:
1/72
Step-by-step explanation:
Given that Ashley rolls a die, flips a corner, and then roll the die again.
Since he rolls a die two times, the number of total possible outcomes for each roll will be equal to 6
Also, the number of possible outcomes for a coin will be equal to 2
What is the probability that he will roll to our numbers And that the coin will land on heads
The probability will be
1/6 ×1/6 × 1/2 = 1/72

Answer:
Correct Answer: Option A
Step-by-step explanation:
cos(x + 25o) = sin 45o
using cos θ = sin(90 - θ)
cos(x + 25o) = cos(90 - 45)
cos(x + 25o) = cos 45
x + 25 = 45
x = 45 - 25
x = 20o

Is 225 a perfect square and a perfect cube?
Answer:
Yes, it is!
Step-by-step explanation:
If 8b-9=b then 7b=?
Please answer if you can!
Also it’s NOT 1.5
Answer:
9 is your answer.
Step-by-step explanation:
Solve for b. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS.
First, add 9 to both sides:
8b - 9 (+9) = b (+9)
8b = b + 9
Next, subtract b from both sides:
8b (-b) = b (-b) + 9
8b - b = 9
7b = 9
Divide 7 from both sides:
(7b)/7 = (9)/7
b = 9/7
Plug in 9/7 for b in the equation given:
7(b) = 7(9/7) = 9
9 is your answer.

7. The island is rich with hot chili peppers. You can collect 1.6 pecks a day. How many liters could you collect in 1 week?
The required liters of hot chili papers collected in a week is 98.56 liters.
What is a unit of measurement?Unit of measurement is defined as every entity having its measures in dimensions, weight, and time. Such as for length we have a meter, for liquid we have liters, and so on.
1 peck = 8.8 liters
1.6 peck = 8.8 × 1.6 liters
1.6 pecks = 14.08 liters
So, in 1-week liter that could be collected is given as,
⇒ 14.08 × 7 [1 week = 7 days]
⇒ 98.56 liters
Thus, the required liters of hot chili papers collected in a week is 98.56 liters.

What is the value of x in the equation LaTeX: \frac{3}{2}\left(4x-2\right)-3x=5-\left(x+2\right) 3 2 ( 4 x − 2 ) − 3 x = 5 − ( x + 2 ) ?
Answer:
x = 3/2
Step-by-step explanation:
x = 3/2
Step-by-step explanation:
Given the equation 3/2(4x-2)-3x = 5-(x+2)
Open the parenthesis
3/2(4x) - 3/2(2) -3x = 5-x-2
6x-3-3x = 3-x
3x-3 = 3-x
Collect like terms
3x+x = 3+3
4x = 6
Divide both sides by
4x/4 = 6/4
x = 3/2
Hence the value of x is 3/2
18x + 3y = -21 slope intercept form
Answer: y=-6x-7
Step-by-step explanation:
Slope-intercept form is y=mx+b. This means, we want to isolate y.
18x+3y=-21 [subtract both sides by 18x]
3y=-18x-21 [divide both sides by 3]
y=-6x-7
Now, our equation is in slope-intercept form.

draw an angular bisector from P to QR in which it intersect wit Qr at point S
now we have two triangle : QPS and RSP
in which angle : QPS=RPS ( PS is angular bisector)
and we have angle Q and angle R are equal
and PS is common side
this makes triangle QPS and RSP are congruent by AAS(angle angle side)
which also means that pQ=PR ( proved)

________________
Answer:
c
Step-by-step explanation:
35/2=17.5 *2= 35+35+35= 105
6.5% of 105 is 6.83, so 105+ 6.83= 111.83

30. When asked his age, the algebra teacher said, "If you
square my age, then subtract 23 times my age, the
result is 50. How old is be?
F. 23
G. 25
H. 27
J. 46
K. 50
Answer:
25 years old
Step-by-step explanation:
Let the teacher's age be a.
Then:
a^2 - 23a = 50
In standard form, this quadratic is
x^2 - 23a - 50 = 0
Factoring this, we get (x - 25)(x + 2) = 0
So a is either 25 or a is -2. Only a = 25 is relevant here.

were the prices of the other two houses? (SHOW WORKING)
Answer:
Step-by-step explanation:

let the total price of houses=x
then
[tex]\frac{3}{13} x=240,000\\x=240,000 \times \frac{13}{3} =1,040,000\\price of first house=1,040,000 \times \frac{6}{13} =480,000\\price~of~second~house=1,040,000 \times \frac{4}{13}=320,000[/tex]
