Given: △EIJ, k(O, r)
EI = EJ = r=10 cm
EP ⊥ IJ
Find: JP
Answer:
[tex]JP=5\sqrt{3}\ cm[/tex]
Step-by-step explanation:
Connecting points O and E and points O and J, we get triangle EOJ. This triangle is equilateral triangle, because OJ=OE=JE=r=10 cm.
Since EP⊥IJ, then segment JP is the height of the triangle EOJ.
The height of the equilateral triangle can be found using formula
[tex]h=\dfrac{a\sqrt{3}}{2},[/tex]
where a is the side length.
So,
[tex]h=\dfrac{10\sqrt{3}}{2}=5\sqrt{3}\ cm.[/tex]
Determine whether the function f(x) = -2x - 5x is even, odd, or neither.
Answer: odd
Step-by-step explanation:
A function is even if for any input value x and -x there is the same output value y. In other words, a function is even if:
[tex]f (-x) = f (x)[/tex]
A function is odd if it is true that:
[tex]f (-x) = -f (x)[/tex]
Then we must test if [tex]f(-x) = f(x)[/tex] for the function: [tex]f(x)=-2x - 5x[/tex]
[tex]f(-x)=-2(-x) - 5(-x)[/tex]
[tex]f(-x)=2x + 5x[/tex]
So [tex]f(-x) \neq f(x)[/tex]
The function is not even
Now we must test if [tex]f (-x) = -f (x)[/tex] for the function.
[tex]f(-x)=-2(-x) - 5(-x)[/tex]
[tex]f(-x)=2x + 5x[/tex]
[tex]f(-x)=-(-2x -5x)[/tex] and [tex]f(x)=-2x - 5x[/tex]
So [tex]f(-x) = -f(x)[/tex]
Finally the function is odd

Answer: $360
Step-by-step explanation:
Let Mp the manufacturing price.
First step:
Manufacturer sells at a profit of 25% = Mp + Mp·0.25 = Mp·1.25
Second step:
Agency sells at a profit of 10% = 1.25Mp + 1.25Mp·0.10 = Mp·1.375
Third step:
Shopkeeper sells at a profit of 20% = 1.375Mp + 1.375Mp·0.20 = Mp·1.65
Then the final price = 1.65·Mp
1.65Mp = $594
Mp = $594/1.65 = $360 ►Manufacturer price
Answer: $360
Verification
Manufacturer sells at a profit of 25% = 25/100 = 0.25:
$360 + $360·0.25 = $360(1 + 0.25) = $360 + $90 = $450
Agency sells at a profit of 10% = 10/100 = 0.10:
$450 + $450·0.10 = $450(1 + 0.10) = $450 + $45 = $495
Shopkeeper sells at a profit of 20% = 20/100 = 0.20
$495 + $495·0.20 = $495(1 + 0.20) = $495 + $99 = $594 Checked!

write the slope intercept inequality (0,2) (-1,-2)
Hey there! :)
(0, 2) & (-1, -2)
Slope-intercept form is : y=mx+b , where m=slope, b=y-intercept
First, we must find the slope using the slope formula, which is :
m = y2-y1/x2-x1
Where y2 = -2 ; y1 = 2 ; x2 = -1 ; x1 = 0
Now, let's plug and chug! :)
m = (-2 - 2) / (-1 - 0)
Simplify.
m = -4/-1 --> Therefore, our slope is : m = 4
Now that we have the slope, we can plug this (and our original coordinates) into point-slope form, which is : y - y1 = m(x - x1) -> use the coordinates (0, 2)
y - 2 = 4(x - 0)
Simplify.
y - 2 = 4x
Add 2 to both sides.
y = 4x + 2

Step-by-step explanation:
Answer:
The amount of money David spent is $115.
Step-by-step explanation:
Consider the provided information.
David had $350. After shopping, he was left with $235.
Let the money spent by David is c.
As some money are spent from the total amount, So use a "-" sign and put the equation equals to 235, as this is the amount he left with.
The equation can be represented as:
350 - c = 235
Now simplify the above equation in order to find the money spent by David.
Isolate the variable by adding c and subtracting 235 from both sides.
350 - c + c -235 = 235 + c -235
115 = c
Hence, the amount of money David spent is $115.
BC is tangent to circle A at point B. What is m2ACB if mZCAB = 22° ?
Answer:
68°
Step-by-step explanation:
We know that sum of 3 angles in a triangle is 180°.
In ΔBAC, there are angles B, A, and C. Thus we can say:
B + A + C = 180
Since, BC is tangent to circle, the point of tangency, B is a 90 degree angle. So angle B is 90.
Also, given angle CAB is 22, which, in other word, is angle A is 22.
Thus, we can write:
B + A + C = 180
90 + 22 + C = 180
112 + C = 180
C = 180 - 112 = 68
Measure of angle ACB = 68°
The measure of angle ACB is 68°.
We know that sum of 3 angles in a triangle is 180°.
In ΔBAC, there are angles B, A, and C. Thus we can say:
B + A + C = 180
Since, BC is tangent to circle, the point of tangency, B is a 90 degree angle. So angle B is 90.
Also, given angle CAB is 22, which, in other word, is angle A is 22.
Thus, we can write:
B + A + C = 180
90 + 22 + C = 180
112 + C = 180
C = 180 - 112 = 68

Which binomial is equivalent to (xy + z)(xy − z)?
Final answer:
The binomial equivalent to (xy + z)(xy - z) is found by applying the difference of squares formula, resulting in x²y² - z².
Explanation:
The question asks which binomial is equivalent to the expression (xy + z)(xy - z). This can be simplified using the difference of squares formula, which is a² - b² = (a + b)(a - b). In this case, a is xy and b is z.
Applying the formula, we have:
First, square a: (xy)² = x²y²
Then, square b: z²
Subtract the square of b from the square of a to get the answer: x²y² - z²
Therefore, the binomial equivalent to (xy + z)(xy - z) is x²y² - z².

A pot of stew is placed on a stove to heat. The temperature of the liquid reaches 170°F, and then the pot is taken off the burner and placed on a kitchen counter. The temperature of the air in the kitchen is 76°F.
If k = 0.34, the temperature of the liquid after 7 hours will be
ºF. (Hint: Use Newton’s cooling model.)
Final answer:
To calculate the temperature of the liquid after 7 hours, you can use Newton's cooling model. By plugging in the initial temperature, the surrounding temperature, and the cooling constant into the equation T = T0 + (T1 - T0) * e(-kt), you can calculate the temperature after 7 hours. In this case, the temperature after 7 hours is approximately 152.85°F.
Explanation:
In this problem, we can use Newton's cooling model to determine the temperature of the liquid after 7 hours. Newton's cooling model states that the rate of heat loss or gain is directly proportional to the temperature difference between the object and its surroundings. Using the equation T = T0 + (T1 - T0) * e(-kt), where T is the temperature at time t, T0 is the initial temperature, T1 is the surrounding temperature, k is the cooling constant, and e is the base of the natural logarithm, we can calculate the temperature after 7 hours.
Convert the initial temperature, the surrounding temperature, and the time to Kelvin.
Plug the values into the equation and calculate the temperature after 7 hours.
Using the given values of T0 = 170°F, T1 = 76°F, and k = 0.34, we can calculate the temperature after 7 hours.
T0 = 170°F + 459.67 = 629.67 K
T1 = 76°F + 459.67 = 535.67 K
T = 629.67 + (535.67 - 629.67) * e⁻°³⁴*⁷
T ≈ 152.85°F

What is the domain of y= 2x - 4/x^2 - 4?
Answer:
{x while x ≠2, -2}
Step-by-step explanation:
First let's define domain,
Domain is the set of all values on which the function is defined i.e. the function doesn't approach to infinity.
Given function is:
[tex]y = \frac{2x-4}{x^{2} -4}[/tex]
We will look for all the values of x on which the function will become undefined:
We can see that x= 2 and x=-2 will make the denominator zero as there is x^2 involved. The denominator zero will make the function undefined.
So, the domain of the function is set of all real numbers except 2 nd -2 {x while x ≠2, -2} ..
Answer:
[tex](-\infty,-2)\cup (-2,2)\cup (2,+\infty)[/tex]
Step-by-step explanation:
The given rational expression is:
[tex]y=\frac{2x-4}{x^2-4}[/tex]
We factor this expression to obtain:
[tex]y=\frac{2(x-2)}{(x-2)(x+2)}[/tex]
We can see that, this rational function has a hole at x=2 and a vertical asymptote at x=-2
Therefore the domain is
[tex]x\ne 2\: and\:x\ne -2[/tex]
Or
[tex](-\infty,-2)\cup (-2,2)\cup (2,+\infty)[/tex]
You select a card from a standard shuffled deck of 52 cards. Without replacing, you select another card. Find the probability that you select a black card, then a red card.
In a standard shuffled deck of 52 cards, half of the cards are black and half of the cards are red: (26 black cards, 26 red cards).
Since we are interested in pulling a black card first, the probability is 26/52.
Without replacing the card we have chosen, we are left with 51 total cards in the entire deck (25 black cards, 26 red cards).
Now that we want to pull a red card, we know that the probability will be 26/51.
Since we are interested in both events occurring simultaneously, we must multiply the probability of the first by the probability of the second, aka: (26/52) * (26/51)
The answer we are given is 0.2549
The probability of picking a black card and then a red card from a standard deck without replacement is 13/51.
To calculate the probability of selecting a black card and then a red card from a standard deck without replacement, we need to consider the sequence of the two events. Initially, the deck contains 26 black cards (spades and clubs) and 26 red cards (diamonds and hearts). The probability P(A) of picking a black card first is 26/52 or 1/2.
After one black card has been removed, there are now 51 cards left in the deck with 26 red cards remaining. The probability P(B) of then picking a red card is 26/51. To find the overall probability of both events happening in sequence, we multiply the probabilities:
[tex]P(A and B) = P(A) \times P(B) = (\frac{1}{2}) \times (\frac{26}{51})[/tex]
This simplifies to P(A and B) = [tex](\frac{26}{102})[/tex] which can be further simplified to [tex](\frac{13}{51}).[/tex]

If f(x) = 4x + 5, which of these is the inverse of f(x)?
Answer:
A
Step-by-step explanation:
y=4x+5
x=4y+5
4y+5=x
4y+5-5=x-5
4y=x-5
4y/4= x/4 - 5/4
y= x-5/4
To find the inverse of the function f(x) = 4x + 5, switch x and y in the equation, then solve for y to get the inverse function, which is f-1(x) = (x - 5) / 4.
Explanation:To find the inverse of the function f(x) = 4x + 5, you would follow these steps:
Replace f(x) with y: y = 4x + 5.Switch the roles of x and y: x = 4y + 5.Solve the equation for y to find the inverse function:Subtract 5 from both sides: x - 5 = 4y.Divide by 4: y = (x - 5) / 4.The inverse function is: f-1(x) = (x - 5) / 4.This inverse function will satisfy the condition that f(f-1(x)) = x and f-1(f(x)) = x, which is the defining property of an inverse function.
