Answer:
10 √10
Step-by-step explanation:
Answer:
[tex]10\sqrt{10}[/tex]
Step-by-step explanation:
The largest perfect square of the factors of 1000 is 100. We can therefore convert √1000 like this:
√100 × 10
Next, we separate the numbers inside the √ as such:
√100 × √10
√100 is a perfect square that equals 10. We can therefore put 10 outside the radical and get the final answer to square root of 1000 in simplest radical form as follows:
10√10

What are the x-intercepts of the graph of the function f(x) = x^2 + 4x – 12?
(-6,0). (2.0)
(2. -16). (0, -12)
(-6.0), (2, -16), (2, 0)
(0.-12).(-6, 0), (2, 0)
Answer:
(- 6, 0 ) , (2, 0 )
Step-by-step explanation:
To find the x- intercepts let f(x) = 0, that is
x² + 4x - 12 = 0 ← in standard form
(x + 6)(x - 2) = 0 ← in factored form
Equate each factor to zero and solve for x
x + 6 = 0 ⇒ x = - 6
x - 2 = 0 ⇒ x = 2
Thus the x- intercepts are (- 6, 0 ), (2, 0 )

Can you find the cube
root of a negative number if so I’d it positive or negative
Step-by-step explanation:
Yes. The cube root of a negative number will be negative.
For example, (-2)^3 = -8. The cube root of -8 is -2.
Answer:
Yes, it would be negative
Step-by-step explanation:
Yes, the cube root of a negative number can be found without using imaginary numbers to represent it.
The cube of a number is that number multiplied by itself 3 times so:
a^3 = a*a*a
if "a" is negative then the cube of "a" will be negative. Hence the cube root of a negative number will be negative.

Many states assess the skills of their students in various grades. One program that is available for this purpose is the National Assessment of Educational Progress (NAEP). One of the tests provided by the NAEP assesses the reading skills of twelfth-grade students. In a recent year, the national mean score was 289 and the standard deviation was 37. Assume that these scores are approximately Normally distributed, N(289, 37). How high a score is needed to be in the top 25% of students who take this exam (use technology)?
Answer:
A score of 314 is needed to be in the top 25% of students who take this exam.
Step-by-step explanation:
We are given that one of the tests provided by the NAEP assesses the reading skills of twelfth-grade students. In recent years, the national mean score was 289 and the standard deviation was 37.
Let X = scores of the tests provided by the NAEP
The z-score probability distribution for the normal distribution is given by;
Z = [tex]\frac{X-\mu}{\sigma}[/tex] ~ N(0,1)
where, [tex]\mu[/tex] = national mean score = 289
[tex]\sigma[/tex] = standard deviation = 37
Now, we have to find how high a score is needed to be in the top 25% of students who take this exam, that means;
P(X > x) = 0.25 {where x is the required score}
P( [tex]\frac{X-\mu}{\sigma}[/tex] > [tex]\frac{x-289}{37}[/tex] ) = 0.25
P(Z > [tex]\frac{x-289}{37}[/tex] ) = 0.25
In the z table, the critial value of z that represents the top 25% of the area is given as 0.6745, that is;
[tex]\frac{x-289}{37}=0.6745[/tex]
[tex]{x-289}=0.6745\times 37[/tex]
x = 289 + 24.96 = 313.96 ≈ 314
Hence, a score of 314 is needed to be in the top 25% of students who take this exam.
Determine how many solutions the equation has. If one solution, state the value of x. 4(x – 3) = 2x + 2x – 6 – 6
Answer:
infinite solutions
Step-by-step explanation:
Given
4(x - 3) = 2x + 2x - 6 - 6 ← distribute left side and simplify
4x - 12 = 4x - 12
Since both sides are equal then the equation has an infinite number of solutions.

Starting with the number 10, build a sequence of 5 numbers
Answer:
10, 11, 13, 16, 20
Step-by-step explanation:
Any 4 numbers can be added to the sequence starting with 10. Perhaps you're supposed to use a rule to choose the numbers. For any 4 numbers you might add to the sequence, a rule can be determined.
The rules we usually use are ones that require a constant difference or a constant ratio. The sequence shown above uses the rule that the difference from the previous value is 1 more than the difference between the previous two values.

a door with width 4.20 m has an arc as shown in diagram .Find: a) radius of the arc B) length of the arc to the nearest cm
Answer:
Ok, we know that the width of the door is 4.20m.
Then, if the arc is at the top of the door, we will have that the diameter of that "half circle" will be equal to the width of the door.
Then the diameter of the arc is 4.20m
And the radius is defined as half of the diameter, so we have:
radius = 4.20m/2 = 2.10m
And we can write this in cm (because the probelm ask for it)
1m = 100cm
then 2.10m = 2.1*100cm = 210cm
Now, we know that the perimeter of a circle is:
P = 2*pi*r
where pi = 3.14
Then the perimeter (or arc) of half a circle will be half of that:
Arc = (2*pi*r)/2 = pi*r
and r = 210cm, pi = 3.14
Arc = 3.14*210cm = 659.4cm

The perimeter of each polygon created by the coordinates is 15.2 units
How to find the perimeter of each polygon created by the coordinates?The coordinates are given as:
A(-2, 3), B(3, 1), C(-2, -1), D(-3, 1)
Calculate the distance between each point using
d = √(x2 - x1)^2+ (y2 - y1)^2
So, we have:
dAB = √(-2 - 3)^2+ (3 - 1)^2 = 5.4
dBC = √(3 + 2)^2+ (1 + 1)^2 = 5.4
dCD = √(-2 + 3)^2+ (-1 - 1)^2 = 2.2
dDA = √(-3 + 2)^2+ (1 - 3)^2 = 2.2
The perimeter is calculated as:
P = 5.4 + 5.4 + 2.2 + 2.2
Evaluate
P = 15.2
Hence, the perimeter of each polygon created by the coordinates is 15.2 units

(b) If you put $9050 in the ATM each day, what percent of the days in a month should
you expect to run out of cash?
Answer:
23.33%
Step-by-step explanation:
The computation of the percentage of days in a month for running out of cash is shown below:
Percentage of running out of Cash is
= (Relevant Occurrence of an event ÷ Total number of events) × 100%
where,
The Relevant occurrence of an event is 7 (105,94,101,98,94,96,92)
And, the total number of events is 30 i.e. 30 days
So, the percentage is
= 7 ÷ 30 × 100
= 23.33%
