how to find the hypotnuse
Final answer:
To find the hypotenuse of a right triangle, apply the Pythagorean theorem: a² + b² = c². After squaring the lengths of the two other sides and adding them together, take the square root of the sum to get the length of the hypotenuse, which is approximately 10.3 units in the example provided.
Explanation:
To find the hypotenuse of a right triangle, you can use the Pythagorean theorem, which states that the square of the hypotenuse (c) is equal to the sum of the squares of the other two sides (a and b). This can be written as the equation a² + b² = c². To solve for the hypotenuse, you would rearrange the equation to c = √(a² + b²).
For example, if the legs of a right triangle measure 9 and 5 units:
First, square both of the leg lengths: 9² = 81 and 5² = 25.Add these two values together: 81 + 25 = 106.Take the square root of the sum: √106 ≈ 10.3 units.Thus, the hypotenuse would measure approximately 10.3 units, where we use three significant figures for precision in measurement.

Solve for x: -4 [x 5] = -16
The solution to the equation -4[x + 5] = -16 is x = -1.
To solve the equation -4[x + 5] = -16 for x, we will follow these steps:
First, we need to isolate the term with the variable. We can start by dividing both sides of the equation by -4 to get rid of the coefficient:
-4[x + 5] / -4 = -16 / -4
Simplifying both sides, we get:
x + 5 = 4
Next, solve for x by subtracting 5 from both sides:
x + 5 - 5 = 4 - 5
Simplifying this, we find:
x = -1

What fraction is £1 of 13p?
The function h(x) is quadratic and h(3) = h(–10) = 0. Which could represent h(x)?
h(x) = x2 – 13x – 30
h(x) = x2 – 7x – 30
h(x) = 2x2 + 26x – 60
h(x) = 2x2 + 14x – 60
Answer:
h(x) = 2x2 + 14x – 60 (D)
Step-by-step explanation:
The quadratic function that represents h(x) with roots at 3 and -10 is h(x) = x^2 - 7x - 30 since it correctly reflects the sum and product of its roots.
The question asks us to find which function could represent h(x), given that h(3) = h(–10) = 0. This means the quadratic function has roots at x = 3 and x = -10. A quadratic function with these roots can be written as h(x) = a(x - 3)(x + 10), where a is a non-zero coefficient.
By expanding this expression, we would get h(x) = a(x^2 + 7x - 30). We can then see if any of the given options matches this form upon factoring out the leading coefficient.
Comparing the given options:
h(x) = x^2 - 13x - 30 does not match because the sum of the roots should be -7 based on the roots 3 and -10.h(x) = x^2 - 7x - 30 matches the expected roots since the sum of the roots (-7) and the product of the roots (-30) align with the roots 3 and -10.h(x) = 2x^2 + 26x - 60 does not match because the coefficient of x is positive, while the sum of the roots derived from the roots of the function is negative.h(x) = 2x^2 + 14x - 60 does not match for similar reasons to the previous one and also the coefficients do not align.Therefore, the correct function that could represent h(x) is h(x) = x^2 - 7x - 30.

Two numbers are in a ratio of 3:6 their sum is 63 find the bigger number
To find the bigger number in the given ratio of 3:6 with a sum of 63, simplify the ratio to 1:2, assign a variable to the smaller number, and solve for the larger one. The bigger number is found to be 42.
Explanation:To find the bigger number when two numbers are in a ratio of 3:6 and their sum is 63, first simplify the ratio to its lowest terms. The ratio 3:6 simplifies to 1:2, since both terms can be divided by 3. Let's assign the variable x to the smaller number, which corresponds to the '1' part of the ratio. Therefore, the bigger number is twice the smaller one, so it can be represented as 2x.
The sum of the two numbers is given by the equation x + 2x = 63. Combine like terms to get 3x = 63. Dividing both sides by 3 gives x = 21. Since 2x represents the bigger number, we have 2x = 2 imes 21 = 42.
Hence, the bigger number in this ratio is 42.
What is the explicit rule for this geometric sequence? 2, 6, 18, 54, …
Answer:
A term at position n can be expressed as \[2*3^{n-1}\]
Step-by-step explanation:
The given geometric sequence is 2, 6, 18, 54, …
Starting term = 2
Second term = 6
So second term is 3 times the first term.
Similarly, Third term = 18
This is 3 times the second term, that is , 3 * 6
Fourth term is is 54.
This is 3 times the third term, that is , 3 * 18
Generalizing, a term in the sequence can be expressed as \[2*3^{n-1}\]
where n represents the position of the term in the sequence.
what is 7x10^-5 in decimals
7x10^-5 as a decimal is 0.00007, achieved by multiplying 7 by 0.00001, which represents 10^-5.
To convert 7x10^-5 into decimal form, you can use the concept that a negative exponent indicates the inverse. This means that 10^-5 is the same as 1/10^5 or 1 divided by 100,000. Thus, to find 7x10^-5 in decimal form, you multiply 7 by 0.00001.
Here's the calculation:
7 x 0.00001 = 0.00007
Therefore, 7x10^-5 in decimal form is 0.00007.

Final answer:
The correct system of equations modeling Jenna's purchase of tropical fish, where x is the number of parrotfish and y is the number of triggerfish, is x + y = 280 and y = 4x, which is option A.
Explanation:
The problem given is about modeling a real-world situation with a system of equations where x represents the number of parrotfish Jenna bought and y represents the number of triggerfish she bought. Jenna bought 280 tropical fish for a museum display, and she bought 4 times as many triggerfish as parrotfish. The system of equations that models this situation is:
x + y = 280
y = 4x
This matches option A from the given choices. The first equation represents the total number of fish Jenna bought, while the second equation represents the relationship between the number of triggerfish and parrotfish, with the triggerfish being four times the number of parrotfish. To solve, substitute the second equation into the first to find the values of x and y.

If you were to place $5,000 in a savings account that pays 6% interest compounded continuously, how much money will you have after 4 years? Assume you make no other deposits or withdrawals.
A. $6,356.25
B. $11,821.07
C. $5,024
D. $6,312.38
...?
Answer:
Option D - $6312.38
Step-by-step explanation:
Given : If you were to place $5,000 in a savings account that pays 6% interest compounded continuously.
To find : How much money will you have after 4 years?
Solution :
Using compound interest formula,
[tex]A=P(1+r)^t[/tex]
Where A is the amount,
P is the principle P=$5000
r is the rate r=6%=0.06
t is the time t= 4 years
Substitute the value,
[tex]A=P(1+r)^t[/tex]
[tex]A=(5000)(1+0.06)^4[/tex]
[tex]A=(5000)(1.06)^4[/tex]
[tex]A=5000\times 1.262[/tex]
[tex]A=6312.38[/tex]
The money he have after 4 years is $6312.38
Therefore, Option D is correct.
Answer:
A. $6,356.25
Step-by-step explanation:
To calculate the amount of money you will have after 4 years in a savings account with continuous compounding, we can use the formula:
A = P * e^(rt)
Where:
A = the amount of money accumulated after t years
P = the initial principal amount (in this case, $5,000)
e = the base of the natural logarithm (approximately 2.71828)
r = the annual interest rate (in decimal form, so 6% becomes 0.06)
t = the number of years (in this case, 4)
Plugging in the values, we get:
A = 5000 * e^(0.06 * 4)
Using a calculator, we can evaluate this expression:
A ≈ 5000 * 2.71828^(0.24)
A ≈ 5000 * 1.276281
A ≈ 6381.405
Rounding to the nearest cent, the amount of money you will have after 4 years is approximately $6,381.41.
Therefore, the closest answer option is A. $6,356.25.

What is the length of the conjugate axis?
(x-1)^2/25-(y+3)^2/9=1 ...?
Answer:
Length of the conjugate axis is 6 units.
Step-by-step explanation:
Given Equation is ,
[tex]\frac{(x-1)^2}{25}-\frac{(y+3)^2}{9}=1[/tex]
To find: Length of the conjugate axis.
We know that given equation is Equation of Hyperbola.
First Transverse Axis: Axis passing through the vertices is called the transverse axis. Length of the transverse axis is 2a.
Now, Conjugate Axis: Axis which is perpendicular to the transverse axis through the center is called the conjugate axis. Length of the Conjugate axis is 2b.
Equation in standard form is written as ,
[tex]\frac{(x-h)^2}{a^2}-\frac{(y-k)^2}{b^2}=1[/tex]
So, Comparing with Standard equation,
we get, a² = 25 ⇒ a = 5 and b² = 9 ⇒ b = 3
Thus, Length of the conjugate axis = 2 × 3 = 6 unit
Therefore, Length of the conjugate axis is 6 units.
For the given equation of hyperbola:
[tex]\dfrac{(x-1)^2}{25}-\dfrac{(y+3)^2}{9}=1[/tex]
The length of the conjugate axis is 6 units.
In analytic geometry, a hyperbola is a conic section created when a plane meets a double right circular cone at an angle that overlaps both cone halves.
The standard equation of the hyperbola is,
[tex]\dfrac{(x-h)^2}{a^2}- \dfrac{(y-k)^2}{b^2} =1[/tex]
Where,
a is half of the transverse axis.
b is the half of the conjugate axis.
The given equation is,
[tex]\dfrac{(x-1)^2}{25}-\dfrac{(y+3)^2}{9}=1[/tex]
Comparing it with the above standard equation, we get:
a² = 25
⇒ a = ± 5
b² = 9
⇒ b = ± 3
Since, the length of the conjugate axis of hyperbola = 2b
Therefore,
The length of the conjugate axis:
= 2x3
= 6 units.
Hence,
The required length of the conjugate axis is 6 units.
