What is the measure of the angle formed by the minute hand and the hour hand of a clock when the clock shows 4:00?

Answers

Answer 1
The answer to this is 120. 
Answer 2

Answer:

[tex]120^o[/tex]

Step-by-step explanation:

We are asked to find the measure of the angle formed by the minute hand and the hour hand of a clock when the clock shows 4:00.

Since we know that clock is a circle made of 360 degrees.

Angle described by minute hand in one minute equals to 6 degrees (360/60). Angle described by hour hand in 1 hour equals 30 degrees (360/12).

At 4:00 minute hand will be at 12 and hour hand will be at 4. So we will multiply 4 by 30 to find the measure of angle formed when the clock shows 4:00.

[tex]\text{Measure of angle}=4\times 30^o[/tex]

[tex]\text{Measure of angle}=120^o[/tex]

Therefore, the measure of the angle formed by the minute hand and the hour hand of a clock, when the clock shows 4:00 is 120 degrees.

Lars deposited $50 into a savings account. According to the rule of 72, what interest rate will cause his money to double in approximately 29 years?

Answers

The rate that will double Lars deposit of $50 in 29 years will be calculated as follows:
Suppose the account used was using compound interest. Thus to determine his future value we shall use the formula:
FV=P(1+r)^n
where:
FV is future value
p=principle
r=rate
n=periods
from the information given
FV=$100
p=$50
n=29 years
we are required to find r
thus
100=50(1+r)^29
100/50=(1+r)^29
2=(1+r)^29
2^(1/29)=1+r
1.02419=1+r
hence:
r=0.02419~2.419%

A probability experiment consists of rolling a a 6 6​-sided die. find the probability of the event below. rolling a number with exactly 2 not necessarily unique prime factors number with exactly 2 not necessarily unique prime factors

Answers

The probability of rolling a number with exactly two prime factors on a six-sided die is 1/3, as there are two outcomes (4 and 6) with exactly two prime factors and six possible outcomes in total.

The student is asking about the probability of an event in a probability experiment involving rolling a single six-sided die. The specific event of interest is rolling a number with exactly two, not necessarily unique, prime factors. On a standard six-sided die, the faces are labeled with the numbers 1 through 6. When considering the numbers on a die with two prime factors, we must first identify which of these numbers have exactly two prime factors. The numbers are:

4 has two prime factors: 2 and 2 (2 squared).6 has two prime factors: 2 and 3.

The other numbers (1, 2, 3, and 5) have fewer than two prime factors. Since 4 and 6 are the only outcomes with exactly two prime factors, we have two favorable outcomes out of six possible outcomes on a six-sided die.

Thus, the probability of rolling a number with exactly two prime factors is:

Probability = Number of favorable outcomes / Total number of possible outcomes

Probability = 2 / 6 = 1 / 3

Therefore, the probability of the event is 1/3, or approximately 0.3333 (repeating).

Find f(1/4) when f(x)=2x^2+9x-7

Answers

Final answer:

To find f(1/4) when f(x)=2x^2+9x-7, substitute x=1/4 into the function and simplify.

Explanation:

To find f(1/4) when f(x) = 2x² + 9x - 7, we substitute x = 1/4 into the function.

Plugging in the value of x, we have f(1/4) = 2(1/4)² + 9(1/4) - 7.

Simplifying the expression, we get f(1/4) = 2/16 + 9/4 - 7. Evaluating the fractions and subtracting, we find that f(1/4) = -45/16.

Use the inverse of the function y = x2 − 18x to find the unknown values. y=+/= square root of bx+c+d

Answers

y = x2 - 18x

 We look for the inverse of the function.
 To do this, let's determine the value of x:
 y = x2 - 18x
 y = (x + (-18/2)) ^ 2 - ((-18) ^ 2/4) + 0
 y = (x - 9) ^ 2 - 81
 y + 81 = (x - 9) ^ 2
 +/- root (y + 81) = (x - 9)
 +/- root (y + 81) + 9 = x
 We return the change:
 f (x) ^ - 1 = +/- root (x + 81) + 9
 Therefore, the values sought are:
 b = 1
 c = 81
 d = 9
 Answer: 
 f (x) ^ - 1 = +/- root (x + 81) + 9 
 b = 1
 c = 81
 d = 9

The inverse of a function is its opposite

The values of the unknown are: b = 1, c = 81 and d = 9

The function is given as:

[tex]y = x^2 - 18x[/tex]

Rewrite the equation in vertex form as:

[tex]y = (x - 9)^2 - 81[/tex]

Swap the positions of x and y

[tex]x = (y - 9)^2 - 81[/tex]

Add 81 to both sides

[tex](y - 9)^2 = x + 81[/tex]

take the square roots of both sides

[tex]y - 9 = \pm\sqrt{x + 81}[/tex]

Add 9 to both sides

[tex]y = \pm\sqrt{x + 81} + 9[/tex]

By comparison, the values of the unknown are:

b = 1, c = 81 and d = 9

Sean tried to drink a slushy as fast as he could. He drank the slushy at a constant rate. There were originally 275 milliliters of slushy in the cup. After 13 seconds, 210 milliliters remained. How long did it take Sean to drink all the slushy?

Answers

Answer: It took Sean 55 seconds to drink all the slushy


Solution:

Original Volume: Vo=275 milliliters

After t1=13 seconds, 210 milliliters remained: V1=210 milliliters

He drank the slushy at a constant rate: r

Sean drank V=Vo-V1=275 milliliters-210 milliliters→V=65 milliliters

r=V/t1

r=65 milliliters / 13 seconds

r=5 milliliters/second

Sean will drink the remained volumen in a time t2:

t2=V1/r

t2=210 milliliters / (5 milliliters/second)

t2=42 seconds

Total time to drink: t

t=t1+t2

t=13 seconds + 42 seconds

t=55 seconds

Clayton wants to make a cylindrical case that will fit a bass drum with a height of 14 inches and a diameter of 24 inches. With is the surface area of the case? Use 3.14 \pi[tex] \pi [/tex]

Answers

1. You can solve this problem and calculate the surface area of the case, by applying the formula for calculate the surface area of a cylinder, which is:

 A=2πr²+2πrh

 "A" is the surface area of the cylinder.
 "r" is the radius.
 "h" is the height of the cylinder (h=14 inches).

 2. You need to calculate the radius. So, you have:

 r=Diameter/2
 r=24 inches/2
 r=12 inches.

 3. You already have the height and the radius, so you can substitute these values into the formula (A=2πr²+2πrh) for calculate the surface area of the case:

 A=2πr²+2πrh
 A=2(3.14)(12 inches)²+2(3.14)(12 inches)(14 inches)
 A=904.32 inches²+1055.04 inches²
 A=1959.36 inches²

What is the trigonometric ratio for sin S?

Enter your answer, as a simplified fraction, in the boxes.


Answers

Answer:  [tex]\frac{8}{17}[/tex] or 8:17

Step-by-step explanation:

For any angle x (other than right angle) in a right triangle ,the trigonometric ratio of sin x is given by :-

[tex]\sin x=\frac{\text{side opposite to x}}{\text{Hypotenuse}}[/tex]

Given: A right triangle with hypotenuse = 68 units

The side adjacent to S =  60

Let h be the side opposite to S, then using Pythagoras in the given right triangle, we get

[tex](68)^2=60^2+h^2\\\\\Rightarrow\ h^2=68^2-60^2\\\\\Rightarrow\ h^2=1024\\\\\Rightarrow\ h=\sqrt{1024}=32[/tex]

Thus, the side opposite to S = 32 units

Now,  the trigonometric ratio for sin S is given by :-

[tex]\sin S=\frac{\text{side opposite to S}}{\text{Hypotenuse}}\\\\\Rightarrow\sin S=\frac{32}{68}=\frac{8}{17}[/tex]

Hence, the  trigonometric ratio for sin S =[tex]\frac{8}{17}[/tex] or 8:17

Find the volume of the tetrahedron having the given vertices. (3, −1, 1), (5, −2, 4), (1, 1, 1), (0, 0, 1)

Answers

Given four vertices of a tetrahedron, we need to find its volume.
A(3,-1,1), B(5,-2,4), C(1,1,1), D(0,0,1)

The simplest method is to use vectors.

Here, we calculate the volume of a parallelepiped defined by vectors AB, AC, AD.  The volume of a tetrahedron is one-sixth of the volume of the parallelepiped, V, given by AB.(ACxAD).
Here are the steps:
1. Choose a vertex, say A.  Calculate vectors AB, AC and AD
AB=(5-2,4)-(3,-1,1) = <2, -1, 3>
AC=(1,1,1)-(3,-1,1) = <-2, 2, 0>
AD=(0,0,1)-(3,-1,1) = <-3, 1, 0>
2. Calculate vector cross product ACxAD = <-2,2,0>x<-3,1,0>
  i   j   k
-2 -2  0
-3, 1, 0
=<0-0, 0-0, -2-(-6)>
= <0, 0, 4>
3. Calculate volume of parallelepiped, equal to the dot product AB.(ACxAD), ignore sign, which is arbitrary.
V = |<2, -1, 3>.<0,0,4>| = |12| = 12
4. Calculate volume of tetrahedron, which is one-sixth of volume of parallelepiped
V(tetrahedron) = V/6= 12/6 = 2
