Answer:
y ≥ 2
Step-by-step explanation:
The range is all of the values that f(x) can have. In order to find the range, let's first find the vertex. That's pretty easy to do since f(x) is already written in vertex notation (vertex notation is f(x) = a(x - c)² + d where (c, d) is the vertex). Since c = -5 and d = 2, the vertex is (-5, 2). Because the value of a is positive (a = 3 in this case, which is positive) we know that the parabola opens upward, therefore the vertex is the minimum. This means that the y-coordinate of the vertex is the smallest possible y-value of the function, therefore, since the y-coordinate of the vertex is 2, the range is y ≥ 2. Note that we use ≥ and not >, this is because y can be 2, therefore, it is included in the solution set.
Answer:
Hey there!
First, we must understand what range is. Range is just another word for all the possible y values of the equation.
This equation, f(x) = 3(x+5)² +2 is in vertex form. We see that this creates a parabola with a vertex at (-5, 2) and opens up.
Thus, the range of this graph would be: [2,∞) in interval notation. Note, the [ is used for greater than or equal to, or less than or equal to, and the ")" is used for less than or greater than.
We use ) for ∞, because ∞ is just a concept, not a real number.
Finally, all functions are defined for all values of x means that this is an f(x) function, and the f(x) is equal to something that can be written in terms of x.

A manufacturer drills a hole through the center of a metal sphere of radius R = 8. The hole has a radius r. What value of r will produce a ring whose volume is exactly half the volume of the sphere? (Round your answer to two decimal places.)
Answer:
New radius(r) = 3.65 (Approx)
Step-by-step explanation:
Given:
Radius of sphere(R) = 8
Find:
New radius(r)
Computation:
Volume of sphere = (4/3)πR³
Volume of sphere = (4/3)π(6)³
Volume of sphere = 288π
Volume of ring = (4/3)π(R²-r²)³/²
Half volume of sphere = Volume of ring
288π / 2 = (4/3)π(R²-r²)³/²
144 = (4/3)(6²-r²)³/²
108 = (6²-r²)³/²
New radius(r) = 3.65 (Approx)
How do I solve for y in this equation? 3xy-28=15x
Answer:
x = 28/(3y -15)
Step-by-step explanation:
Put the x-terms on the same side of the equal sign and everything else on the other side. Divide by the coefficient of x.
3xy -28 = 15x . . . . . . given
-28 = 15x -3xy . . . . . subtract 3xy
-28 = x(15 -3y) . . . . . factor out x
-28/(15 -3y) = x . . . . . . divide by the coefficient of x
We prefer to have a positive sign where possible, so we can multiply this by -1/-1 to get ...
x = 28/(3y -15)

Answer:

Step-by-step explanation:
62 = angle BAC since they are vertical angles
angle ABC is a right angle since KL is perpendicular to FG
Adding the angles in triangle ABC
BAC + ABC + BCA = 180
62 + 90 + BCA = 180
152 + BCA = 180
BCA = 180-152
BCA = 28
BCA = x since they are vertical angles
28 = x

Use the number line below, where RS = 7y +5, ST = 2y + 7, and RT = 14y - 28.
a. What is the value of y?
b. Find RS, ST, and RT.
Answer:
a. 8
b. 61, 23, 84
Step-by-step explanation:
As we can see, point S is between points R and T, therefore:
RS + ST = RT7y + 5 + 2y + 7 = 14y - 289y + 12 = 14y - 2814y - 9y = 12 + 285y = 40y = 40/5y = 8------------
RS = 7y+5 = 61ST = 2y + 7= 23RT = 14y - 28 = 84A van can travel 18 miles on each gallon of gasoline. At that rate, how many miles can the van travel on 15 gallons of gasoline? -33 miles -83 miles -120 miles -270 miles

Identify the number that does not belong with the other three. Explain your reasoning (24 points)
Answer:
See explanation
Step-by-step explanation:
The number that would not belong is [tex]\sqrt{48}[/tex] since it is irrational
Answer:
[tex]\sqrt{48}[/tex]
Step-by-step explanation:
Looking at the numbers, we can see that the first number, third, and fourth number are all rational numbers since they either repeat or terminate.
On the other hand, let's try and simplify the square root of 48:
[tex]\sqrt{48}=\sqrt{16\cdot3}=\sqrt{16}\cdot\sqrt3=4\sqrt3[/tex]
The square root of 3 is irrational. Therefore, 4 times the square root of 3 is also irrational. All of the given numbers are rational instead of the second one. So, the second number does not belong .

What is the Subtraction operation?Subtraction is a mathematical operation that deducts the right-hand operand from the left-hand operand.
for example 4 -2 = 2
In mathematics, adding a negative number and a positive number involves combining two quantities with opposite signs. When we add a negative number and a positive number, we can think of it as "subtracting the absolute value of the negative number from the positive number."
For example, if we have -3 + 5, we can rewrite it as 5 - 3, which equals 2. In this case, we are subtracting the absolute value of the negative number (3) from the positive number (5).
Similarly, if we have -7 + 2, we can rewrite it as 2 - 7, which equals -5. In this case, we are subtracting the absolute value of the negative number (7) from the positive number (2), but since the negative number has a larger absolute value, the result is negative.
So, the result of adding a negative number and a positive number will depend on the magnitude of the two numbers and which one is larger.

Peter withdrew 1000 dollars from his bank account today. He uses 500 to fix his car. Then, he divided the money into 5 equal parts and gave away 4 parts and kept 1 part for himself. Finally, he took his wife to the restaurant and spent 60 dollars on meals. Write a numerical expression to represent this situation and then find how much money Peter has now?
Answer:
ok he has $40 left
Step-by-step explanation:
1000-500 = 500
500 - 400 = 100
100-60 = 40
Answer:
Money with Peter = $ 40
Step-by-step explanation:
Let 'x' be the money left with Peter
Money left with Peter after fixing his car = 1000 - 500 = 500
500 is divided into 5 equal parts and 4 parts he gave away. 500 - 400 = 100
x = (1000 - 500) - 400 - 60
= 500 - 400 - 60
= 100 - 60
x =$ 40
25b +15b combine like terms
Answer:

25 + 15 = 40
Answer:
40b
Step-by-step explanation:
We are given the expression:
25b+15b
and asked to simplify.
To simplify, we must combine like terms. Let's analyze the terms.
25b ⇒ has a variable "b"
15b ⇒ also has a variable "b"
The like terms in this expression are the terms with a variable, b.
To combine like terms, add the coefficients and leave a b on the end.

Step-by-step explanation:
Given:
Number of calories everyday = 5120 calories
Number of days = 21
Find:
Total calories eat
Computation:
Total calories eat = Number of calories everyday × Number of days
Total calories eat = 5120 × 21
Total calories eat = 107,520 calories
What is the term, coefficient, constant, and factor of 1/2(base1 + base2)h? (Formula used to find area of trapezoid)
Answer:
i. Term = [tex]\frac{b_{1}h }{2}[/tex] + [tex]\frac{b_{2}h }{2}[/tex]
ii. Coefficient = [tex]\frac{1}{2}[/tex]
iii. Constant = [tex]\frac{1}{2}[/tex]
iv. Factor = [tex]\frac{h}{2}[/tex]
Step-by-step explanation:
A trapezoid is a quadrilateral which has its base parallel to the opposite side. It's area can be determined by;
Area of trapezium = [tex]\frac{1}{2}[/tex] ([tex]b_{1}[/tex] + [tex]b_{2}[/tex])h
Where [tex]b_{1}[/tex] is the measure of length of its fist base, [tex]b_{2}[/tex] is the measure of its second base and h is its height.
Considering the given question,
Term = [tex]\frac{b_{1}h }{2}[/tex] + [tex]\frac{b_{2}h }{2}[/tex]
Coefficient = [tex]\frac{1}{2}[/tex]
Constant = [tex]\frac{1}{2}[/tex]
Factor = [tex]\frac{h}{2}[/tex]

[tex]2.\ 3x = 1[/tex]
For the first expression, we multiply both sides by 3
[tex]3 * \frac{x}{3} = 1 * 3[/tex]
[tex]x = 1 * 3[/tex]
[tex]x = 3[/tex]
For the second; divide both sides by 2

After 3 years, he paid Rs. 70700 and gave a buffalo to clear off the debt. What is the
cost of the buffalo?
Answer:
Rs. 112000
Step-by-step explanation:
Borrowed money = Rs. 126000Interest rate = 15% PA simpleTime = 3 yearsHari is due to pay after 3 years:
126000* (1+ 3*15/100) = 182700He pays Rs. 70700, remaining money is cleared by giving buffalo.
Cost of buffalo:
182700 - 70700= Rs. 112000Answer is: Rs. 112000
Answer:
Solution,
principal(P)= Rs. 126000
Rate(R)=15%
Time(T)=3 years
Money paid=Rs.70700
Cost of buffalo=?
We know that,
Interest=P*T*R
100
= Rs. 126000*3*15
100
= Rs. 56700
Now,
Amount(A)=P+I
=Rs. ( 56700+126000)
= Rs.182700
Again,
by the question,
Cost of buffalo= Amount- Money paid
= Rs.(182700- 70700)
= Rs. 112000
Therefore, the cost of buffalo is Rs. 112000.
