Answer:
If x^n = y, then y is a power of x
Step-by-step explanation:
Take two numbers, x & y
To check whether, y is a a power of x
By hit & trial method, calculate x^n (approximately considered to near y). Try for many such no.s
If at any value x^n = y, then y is a power of x
Ex : Let x = 5, y = 625
By hit & trial, n = 3 or 4,
5^3 = 125 , 5^4 = 625
So, 625 is a power of x

Answer:
Step-by-step explanation:
q in (-oo:+oo)
q/4+7 = 5 // - 5
q/4-5+7 = 0
1/4*q+2 = 0 // - 2

q = -2/1/4
q = -8
q = -8
Which of the following is a quadratic equation that has the roots x = 3 and x = −4?
Answer:
x^2 + x = 12
Step-by-step explanation:
(x - 3)(x + 4) = 0
x^2 + 4x - 3x - 12 = 0
x^2 + x - 12 = 0
x^2 + x = 12
The quadratic equation that has the roots x = 3 and x = −4 will be x²+x-12=0.
Any equation using the formula ax² + bx + c = 0 When x is a variable and a, b, and c are any real values; a quadratic equation is one where a≠0.
It is given that the quadratic equation that has the roots x = 3 and x = −4.
We know that one such equation is provided by x²-(a+b)x+ab=0 if a and b are the roots of a quadratic equation.
x²-(a+b)x+ab=0
Substitute the value of an as 3 and b as -4.
x²-(3-4)x+(3)(-4)=0
x²-(-1)x-12=0
x²+x-12=0
Thus, the obtained quadratic equation will be x²+x-12=0.

DIRECTIONS: Each number if 4 less than 3 times the previous number.
Starting with the number 10, build a sequence of 5 numbers.
Answer:
10, 26, 74, 218, 650
Step-by-step explanation:
n * 3 - 4
Answer:
The sequence of 5 terms is: 10, 26, 74, 218, 650
Step-by-step explanation:
By following the instructions, we can build the sequence by doing:
[tex]a_n= 3\,a_{n-1}-4[/tex]
So, using this formula and starting with 10 we get
[tex]a_1=10\\a_2=3\,(10)-4=26\\a_3=3\,(26)-4= 74\\a_4=3\,(74)-4=218\\a_5=3\,(218)-4=650[/tex]

What is the volume of a rock if it has a density of 1.25g/ml if it has a mass of 7525g?
Answer:
[tex]\boxed{\tt v= 6,020 \ mL}[/tex]
Step-by-step explanation:
The density formula is
[tex]d=\frac{m}{v}[/tex]
Rearrange the formula for v. Multiply both sides of the formula by v, then divide both sides by d.
[tex]d*v=\frac{m}{v}*v[/tex]
[tex]d*v=m[/tex]
[tex]\frac{dv}{d}=\frac{m}{d}[/tex]
[tex]v=\frac{m}{d}[/tex]
The volume can be found by dividing the mass by the density. The mass is 7525 grams and the density is 1.25 grams per milliliter.
[tex]m= 7525 \ g\\d=1.25 \ g/mL[/tex]
[tex]v=\frac{m}{d}[/tex]
[tex]v=\frac{7525\ g}{1.25\ g/mL}[/tex]
Divide. Note that the grams, or "g" will cancel each other out.
[tex]v=\frac{7525 \ }{1.25\ mL}[/tex]
[tex]v=6020 \ mL[/tex]
The volume of the rock is 6,020 milliliters.
Answer:
V = 6020
Step-by-step explanation:
will make it sure and simple
formula of density d = mass / volume
where d = 1.25 g/mL
and mass = 7525 g
plugin values into the formula
1.25 = 7525 / Vol
Vol = 7525 / 1.25
Vol = 6020
Traces of surface x2 + y2 − z2 = 1. Determine the equation for the family of traces in x = n.
Answer:
[tex]\mathbf{y^2 -z^2 =1- n^2}[/tex]
Step-by-step explanation:
Give that:
the surface equation is [tex]x^2 +y^2 -z^2 =1[/tex]
from the family of traces in x = n given that [tex]x^2 +y^2 -z^2 =1[/tex] , the equation can be represented as :
[tex]n^2 +y^2 -z^2 =1[/tex]
[tex]\mathbf{y^2 -z^2 =1- n^2}[/tex]
This represents a family of hyperbola for all values of n expects that n = ± 1
So, if n = ± 1,
Then
[tex]y^2 - z^2 = 0[/tex]
(y-z) (y+z) = 0
y = ± z
So, for n = ± 1, it is a pair of line for y = z, y = -z

The model represents an equation. What value of X makes the equation true?
A) -15
B) -3
C) 15
D) 3
Answer:
D) 3
Step-by-step explanation:
-3x+6=2x-9
subtract 6 from both sides
-3x=2x-15
subtract -2x from both sides
-5x = -15
divide both sides by -5

In triangle ABC, the measure of angle B is 29 more than three times the measure of angle A. The measure of angle is 01" more than the measure of angle A. Find the measure of onch angle
Anglo Ameasures
Angle C is 31, Angle A is 30, and Angle B is 119.
Step-by-step explanation:
The measures of each of the angles in triangle ABC are
A = 18
B = 83
C = 79
Calculating the measure of anglesFrom the question, we are to determine the measure of each of the angles in triangle ABC
From the given information,
The measure of angle B is 29 more than three times the measure of angle A
That is,
B = 3A + 29 ------- (1)
Also, the measure of angle C is 61 more than the measure of angle A
That is,
C = 61 + A --------- (2)
We can also write that
A + B + C = 180 ----- (3) (Sum of angles in a triangles)
Put equations (1) and (2) into equation (3)
A + 3A + 29 + 61 + A = 180
5A + 90 = 180
5A = 180 - 90
5A = 90
A = 90/5
A = 18
Put the value of A into equation (1)
B = 3A + 29
B = 3(18) + 29
B = 54 + 29
B = 83
Put the value of A into equation (2)
C = 61 + A
C = 61 + 18
C = 79
Hence, the measures of each of the angles are
A = 18
B = 83
C = 79

How much will a person pay for 1.4 pounds of bananas at a price of $2.34 per pound
Answer:
$3.276
Step-by-step explanation:
From the question, we are told that the price of banana is
1 pound = $2.34
1.4 pounds = $ y
Cross Multiply
1 pounds × $y = 1.4 pounds × $2.34
$y = 1.4 pounds × $2.34/1 pounds
$y = $3.276
Therefore, a person will pay $3.276 for 1.4 pounds of banana

Determine the slope for a line that passes through points (2,5) and (3, 1).
Answer: -4
Step-by-step explanation:
To find the slope, you want to use the formula [tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex].
[tex]m=\frac{1-5}{3-2} =\frac{-4}{1}=-4[/tex]

It is said that a student’s college GPA (grade point index) can be predicted by his/her HOCS (higher- order cognitive skills) such as problem identification, analytical reasoning, and content integration skills. What other potential predictor variables, numerical and categorical, would you want to use that might lead to the development of a multiple regression model for predicting a student’s college GPA? Briefly describe the direction of the slope that each of these variables should have.
Answer:
apart from using the hoc to predict the college students gpa, some other variables can be used
1. the students intelligent quotient
2. ability to remember
3. study time
4. gym practice
Step-by-step explanation:
1. the students intelligent quotient
gpa has a positive relationship with iq. they are both directly related. The more the iq of a a student, the greater is his ability to understand and have a good gpa. the slope will therefore be positive and be in an upward direction.
2. ability to remember
the gpa of students who have a good ability to remember but do not have a good grasp of the subject may not be high. the slope would be in a slightly upward direction
3. study time
gpa and practice have a positive relationship. the more a student studies, the more likelihood exists of having a better gpa. the slope would be upward bound.
4. gym practice
gpa and gym practice are not related so the slope would be in a downward direction.
when interpreting the direction of relationship after carrying out such an analysis, it is useful to watch out for the accompanying signs of the variables. if the sign of the beta coefficient is positive then a positive relationship with the dependent variable exists.

Step-by-step explanation:
A and B are alternate exterior angles and alternate exterior angles are equal when the lines are parallel
A = B
6x-2 = 4x+48
Subtract 4x from each side
6x-4x-2 = 4x+48-4x
2x-2 = 48
Add 2 to each side
2x-2 +2 = 48+2
2x = 50
Divide by 2
2x/2 = 25
We want to find angle A
A = 6x-2
= 6*25 -2
150 -2
= 148
Answer:
Solution given:
<A=<B{alternate exterior angle are equal}
6x-2=4x+48
6x-4x=48+2
2x=50
x=50/2
x=25
