Please help me with the question below
Answer:
4
Step-by-step explanation:
If Judge is x years old and Eden is 6 years older, then Eden is x + 6 years old.
The second part tells us that Eden will be twice as old as Judge in two years.
This means that in two years: (Eden's age) = 2 * (Judge's age).
Since we know that Eden's age can be represented as x + 6 and Judge's age can be represented as x, we can write this: x + 6 = 2 * x
Simplify the equation:
x + 6 = 2x
6 = x = Judge's age (in two years)
If Judge is 6 two years later, then he must be 4 now.
To check our work, we can just look at the problem. Judge is 4 years old and Eden is 6 years older than Judge (that means Eden is 10 right now). Two years later, Eden is 12 and Judge is 6, so Eden is twice as old as Judge. The answer is correct.
Write a triple integral including limits of integration that gives the volume of the cap of the solid sphere x2+y2+z2≤34 cut off by the plane z=5 and restricted to the first octant. (In your integral, use theta, rho, and phi for θ, rho and ϕ, as needed.) What coordinates are you using? (Enter cartesian, cylindrical, or spherical.) With a= , b= , c= , d= , e= , and f= , Volume = ∫ba∫dc∫fe
Answer:
a = 0
b = [tex]\frac{\pi }{4}[/tex]
c = 0
d = 3
e = 5
f = [tex]\sqrt{34-r^2}[/tex]
Step-by-step explanation:
Equation of the solid sphere = x^2 + y^2 + z^2 ≤ 34 ------- (1)
at Z = 5
since the bottom of the sphere(z) is flat = 5 we will use cylindrical coordinates
concentrating in the first octant as mentioned in the question
at Z = 5 , equation 1 becomes :
x^2 + y^2 + 25 ≤ 34 = x^2 + y^2 = 9
hence the radius around the xy axis = [tex]\sqrt{9}[/tex] = 3
that means the radius is : 0 ≤ r ≤ 4 , 0 ≤ ∅ ≤ [tex]\frac{\pi }{4}[/tex]
next we have to find the upper bound of: Z = ±[tex]\sqrt{34-r^2}[/tex] we will pick out only the positive
5 ≤ z ≤ [tex]\sqrt{34 - r^2}[/tex]
therefore for the Volume = ∫ba∫dc∫fe
a = 0
b = [tex]\frac{\pi }{4}[/tex]
c = 0
d = 3
e = 5
f = [tex]\sqrt{34-r^2}[/tex]

If 5(x-4)+2= -173 what is the value of x?
Answer:
38.2
Step-by-step explanation:
5 (x-4) + 2 = 173
=> 5x - 20 + 2 = 173
=> 5x - 18 = 173
=> 5x - 18 + 18 = 173 + 18
=> 5x = 191
=> 5x/5 = 191/5
=> x = 38.2
So, x is 38.2
Because of the rainy season, the depth in a pond increases 3% each week. Before the rainy season started, the pond was 10 feet deep. What is the equation that best represents the depth of the pond each week? Hint: Use the formula y = P(1 + r)x. y = 10(0.03)x y = 10(0.3)x y = 10(1.3)x y = 10(1.03)x
Answer:
y = 10(1.03)^x
Step-by-step explanation:
In the formula y = p(1 + r)^x, p is the starting amount and r is the growth rate.
In this problem, the starting amount is 10. So, p = 10.
The growth rate is 3% each week, which is the same as 0.03 as a percentage. So, r = 0.03.
Plug these into the equation:
y = 10(1.03)^x will be the equation for this situation
The equation that best represents the depth of the pond each week is y = 10(1.03)× option (D) is correct.
What is an exponential function?It is defined as the function that rapidly increases and the value of the exponential function is always positive. It denotes with exponent y = a×
where a is a constant and a>1
We have:
A pond increases 3% each week.
The exponential growth is represented by:
y = p(1 + r)×
p = 10 feet
r = 3% = 0.03
y = 10(1 + 0.03)×
y = 10(1.03)×
Thus, the equation that best represents the depth of the pond each week is y = 10(1.03)× option (D) is correct.

How do I solve this question? Rayne sold 3 desks at a local trade show. he payed $4.00 to rent the booth. he gave half of his revenue to the carpenter and was left with $185.50. at what price did Rayne sell each desk
Answer:
$125
Step-by-step explanation:
I suspect there's an error in the problem statement. Revenue is the money made from selling the desks. Profit is the revenue from the desks minus the cost of the booth rental.
If Rayne gives half of his profit to the carpenter, and x is the price per desk, then:
185.50 = ½ (3x − 4)
371 = 3x − 4
375 = 3x
x = 125

compare the following fraction
4/3 and 5/2
-3/2. -4/5
Answer:
Step-by-step explanation:
to compare them, we need to convert them into like fractions
4/3 and 5/2
lcm of 3 and 2 is 6
4/3 × 2/2 = 8/6
5/2 × 3/3 = 15/6
15/6 is greater than 8/6
so 5/2 is greater than 4/3
similarly,
-3/2 and -4/5
we need to convert them into like fractions
lcm of 2 and 5 is 10
-3/2 × 5/5 = -15/10
-4/5 × 2/2 = -8/10
-8/10 is greater than -15/10
so -4/5 is greater than -3/2

"Find an equation for the family of linear functions with slope 4. (Use the standard coordinate variables x and y. You may use m for the slope and b for the y-intercept as needed.)"
Answer:
Y= 4x +y1-4x1
4 represent the slope m
+Y1 - 4x1 represent the intercept b
Step-by-step explanation:
Formula for the equation of the linear function
(Y-y1)/(x-x1) = m
We will transform it into the equation form
Y= mx + b
Where m = slope=4
b = intercept
(Y-y1)/(x-x1) = m
(Y-y1)/(x-x1) = 4
(Y-y1)= 4(x-x1)
Y-y1= 4x -4x1
Y= 4x +y1-4x1
4 represent the slope m
+Y1 - 4x1 represent the intercept b
An equation for the family of linear functions with slope 4 is; y = 4x +b
Equation of a straight lineThe equation of a line can be determined by means of the slope as follows;
slope,m = (y-y1)/(x-x1)Therefore, for this scenario;
Slope,m = 4 = (y-y1)/(x-x1)By Cross-product, we have;
4x - 4x1 = y -y1Since, the y-intercept, b is the value of y for which x= 0.
Hence;
4x - 0 = y-by = 4x +bRead more on slope-intercept form;

A survey team is trying to estimate the height of a mountain above a level plain. From one point on the plain, they observe that the angle of elevation to the top of the mountain is 32 ∘ . From a point 2000 feet closer to the mountain along the plain, they find that the angle of elevation is 34 ∘ . How high (in feet) is the mountain?
Answer: 3528.25
Step-by-step explanation:Make a sideview sketch
you should have 2 triangles, one right-angled containing the height and a scalene triangle with angles 24° , 153° (the supplement of 27°) and 3°
the side opposite the 3° angle is 1000
by let the side opposite the 24° be x, (also the hypotenuse of the right-angled triangle)
x/sin24 = 1000/sin3
x = 1000sin24/sin3
let the height of the mountain be h
sin 27 = h/x
h = x sin27 = (1000sin24/sin3)(sin27)
= 3528.25

= 18
-----------------------------------------------------------
Now,let's find out using another method i.e division method
Steps for finding G.C.F by using division method:
Step 1 : Divide the larger number by smaller one.
Step 2 : In case of remaining remainder, divide the first division by that remainder.
Step 3 : Again if remainder leaves, divide the second divisor by the remainder.
Step 4 : Repeat the process until the remainder becomes the zero. So , that the last divisor is the G.C.F
