3. Answer:
x=3/2+1/2√21 or x=3/2+-1/2√21
Step-by-step explanation:
For this equation: a=1, b=-3, c=-3
1x2+−3x+−3=0
Step 1: Use quadratic formula with a=1, b=-3, c=-3.
x=−b±√b^2−4ac/2a
x=−(−3)±√(−3)^2−4(1)(−3)/2(1)
x=3±√21/2
x=3/2+1/2√21 or x=3/2+−1/2√21
Answer:
3: x= 3.7912874, x= 0.79128784

Answer:
I think it is 72%
Step-by-step explanation:
Answer:
A. 12%
Step-by-step explanation:
I counted the number of dots in all, and the number of dots in the columns 7 - 8.
There are 25 dots in allThere are 3 dots in columns 7 - 8.This means that 3/25 of the students in the class have 7 - 8 people in their houses.
Now let's convert the fraction into a decimal, which we'll then convert into a percent.
Let's multiply the numerator and denominator of 3/25 by 4.
We get 12/100!
12/100 as a decimal is 0.12
0.12 as a percent is 12%
Is there a letter which has 12% as an option? Yes, there is! It's A.
The answer is A. 12%

Answer:
x2 = -0.600000
x3 = -0.521600
Step-by-step explanation:
Given the formula;
xn+1 = (xn)³-5/10
x2 = (x1)³-5/10
Given x1 = -1
x2 = (-1)³-5/10
x2 = (-1-5)/10
x2 = -6/10
x2 = -0.600000
x3 = (x3)³-5/10
Given x3 = -0.6
x3 = (-0.6)³-5/10
x3 = (-0.216-5)/10
x3 = -5.216/10
x3 = -0.521600

Round 576.558 to the nearest tenths place
Answer:
576.6
(look at the number by the 10th place and round)
The value of 576.558 after rounding to the nearest tenth-place value is
576.6.
Option A is the correct answer.
What is place value?The place value of a number is given as:
Example:
1234.567
1 = thousand place value
2 = hundred place value
3 = tens place value
4 = ones place value
5 = tenths place value
6 = hundredths place value
7 = thousandths place value
We have,
576.558
The number in the tenth place is 5 bolded underscore.
576.558
Now,
The next value is 5 which is greater or equal to 5 so we will change the tenth place value 5 into 6.
If the next value was 4 or less we will keep the tenth place value 5 as 5.
Now,
The value of 576.558 after rounding to the nearest tenth-place value is
576.6.
Thus,
The value of 576.558 after rounding to the nearest tenth-place value is
576.6.
Option A is the correct answer.

If an = n(an-1) and a1 = 1, what is the value of as?
1) 5
2) 20
3)
120
4) 720
The value of a5 is a5=120.
Here, we have,
given that,
an = n(an-1) and a1 = 1,
now, we have,
a1 = 1
so, we get,
a2 = 2(a1)
= 2
and, a3 = 3(a2) = 6
a4 = 4(a3) = 24
so, we get,
a5 = 5(a4) = 120
Hence, the value of a5 is a5=120.

find the simple interest on each amount 1500 at 11% for two years
Answer:
330.00
Step-by-step explanation:
First, converting R percent to r a decimal
r = R/100 = 11%/100 = 0.11 per year,
then, solving our equation
I = 1500 × 0.11 × 2 = 330
I = $ 330.00
The simple interest accumulated
on a principal of $ 1,500.00
at a rate of 11% per year
for 2 years is $ 330.00.

Gwendolyn placed a 10-foot ladder against the side of her house so that the base of the ladder was 3 feet from the base of the house, as shown in the diagram below. Which measurement in feet is closest to d, the distance from the top of the ladder to the ground?
Answer 9.5
you do the pyragtaham theory thing its A(squared) + B (squared) = C squared
you put the 3 at the A and you put the 10 at the C you sqaure them all up and then subtrct 9 from 100 and you get 91 and then you square root 91 and you get 9.5
The distance from the top of the ladder to the ground is 9.54 ft.
What is a right triangle?"It is a triangle whose one of the angle is 90°"
What is hypotenuse?"The longest side of the right triangle is called as hypotenuse."
What is Pythagoras theorem?"For a right triangle,
c² = a ² + b²,
where c = hypotenuse and a, b are other two sides of right triangle."
For given example,
Gwendolyn placed a ladder against the side of her house.
This means, it makes right triangle with ladder hypotenuse and base of the triangle is the distance between base of the ladder and the base of the house.
Let 'a' be the hypotenuse of triangle, 'b' be the base and 'd' be the distance from the top of the ladder to the ground
⇒ a = 3 ft. and b = 10 ft.
Using Pythagoras theorem,
⇒ b² = a² + d²
⇒ 10² = 3² + d²
⇒ 100 = 9 + d²
⇒ d² = 91
⇒ d = 9.54 ft.
Therefore, the distance from the top of the ladder to the ground is 9.54 ft.
