A triangle is a three-edged polygon with three vertices. The length of the sides of the triangle is 5, 5, and 5√2.
What is a triangle?A triangle is a three-edged polygon with three vertices. It is a fundamental form in geometry. The sum of all the angles of a triangle is always equal to 180°.
Since the two angles are equal, therefore, the length of the two legs of the isosceles right triangle will be equal and will be less than the hypothenuse.
Hence, the length of the sides of the triangle is 5, 5, and 5√2.

Use the function to predict the minimum target heart rate for a person 20 years old. beats per minute
The minimum target heart rate for a person 20 years old is 120 beats per minute
How to predict the minimum target heart rate?The equation of the function is given as:
y = -0.6x + 132
Where x represents the age, and y represents the minimum target heart rate
From the question, we have:
x = 20
Substitute x = 20 in y = -0.6x + 132
This gives
y = -0.6 *20 + 132
Evaluate
y = 120
Hence, the minimum target heart rate for a person 20 years old is 120 beats per minute

Grayson is preheating his oven before using it to bake. The initial temperature of the oven is 65° and the temperature will increase at a rate of 15° per minute after being turned on. What is the temperature of the oven 6 minutes after being turned on? What is the temperature of the oven tt minutes after being turned on?
Answer:
155 Degrees
Step-by-step :
(Time x Rate of Temp) + Initial Temp = Final Temperature
Ex. (6 * 15) + 65 = 155 Degrees
Answer:
The temperature of the oven 6 minutes after being turned on is 155°
The temperature of the oven t minutes after being turned on is 15t + 65
Step-by-step explanation:
y=mx + b
y = y coordinate
m = slope
x = x coordinate
b = y intercept
The y intercept is when x = 0, so the initial temperature
b = 65°
The slope is increase at a rate of per minute after being turned on.
m = 15°
The y coordinate will represent the temperature of the oven after a certain amount of minutes after being turned on
y
The x coordinate will represent the amount of minutes after the oven being turn on
x = t
combine:
What is the temperature of the oven tt minutes after being turned on?
y = 15t + 65
What is the temperature of the oven 6 minutes after being turned on?
t = 6 minutes
y = 15t + 65
y = 15(6) + 65
y = 90 + 65
y = 155

If .111... = 1/x, what is x?
Correct answer will get brainliest
Answer:
x = 9
Step-by-step explanation:
When 1 is divided by 9, we understand it is a non-terminating decimal number because the denominator consists of other number other than 2 and 5.
Now, let's get into how to solve for x :
Divide both sides by .111... :
1/.111... x .111... = 1/.111 x 1/x
1 = 1/(x)(.111....)
Multiply both sides by x :
1(x) = (x)/(x)(.111...)
x = 1/.111...
x = 9 (nearest whole number)
Answer:
[tex]\sf 0.\dot{1}=\dfrac{1}{9}[/tex]
Therefore, x = 9
Step-by-step explanation:
To convert 0.11111... to a fraction:
Equation 1
Let: y = 0.11111...
Equation 2
Multiply both sides by 10:
⇒ y · 10 = 0.11111... · 10
⇒ 10y = 1.11111...
Subtract Equation 1 from Equation 2 to eliminate the recurring digits after the decimal:
⇒ 10y - y = 1.1111... - 0.11111...
⇒ 9y = 1
Divide both sides by 9
[tex]\implies \sf y=\dfrac{1}{9}[/tex]
Therefore,
[tex]\sf 0.\dot{1}=\dfrac{1}{9}[/tex]
So if:
[tex]\sf 0.\dot{1}=\dfrac{1}{x}[/tex]
Then x = 9

There are no horizontal asymptotes and the range is [tex](- \infty,\infty)[/tex].
The end behaviors of the parent function are:

[tex]\textsf{As } x \rightarrow \infty, f(x) \rightarrow \infty[/tex]
To determine the attributes of the given function, compare the given function with the parent function.

[tex]f(x)=- \log_2(x)+5[/tex]
The given function is reflected in the x-axis. Therefore, the end behaviors are a reflection of those of the parent function:
[tex]\textsf{As } x \rightarrow 0^+, f(x) \rightarrow \infty[/tex]
[tex]\textsf{As } x \rightarrow \infty, f(x) \rightarrow - \infty[/tex]
As the given function is translated vertically (5 units up) only, the domain, range and asymptote will not change, since the function has not been translated horizontally.

The range of the function is [tex]\boxed{(- \infty, \infty)}[/tex], and it is [tex]\boxed{\sf decreasing}[/tex] on its domain of [tex]\boxed{(0, \infty)}[/tex].
The end behavior on the LEFT side is as [tex]\boxed{x \rightarrow 0^+}[/tex], [tex]\boxed{f(x) \rightarrow \infty}[/tex], and the end behavior of the RIGHT side is [tex]\boxed{x \rightarrow \infty}[/tex], [tex]\boxed{f(x) \rightarrow -\infty}[/tex].

here is huw's working. 9 days is incorrect. work out the correct answer.
Huw's answer of 9 days is incorrect because more guests would finish the food in less time so the number of days for 30 guests is less than 6 days.
The number of days that the food can last 30 guests is 4 days.
How long will Seaview Hotel's food feed 30 guests?More guests would eat the food faster which means that it would be finished in less days than the 6 days used by 20 guests.
To find the days the food would last 30 guests, use the inverse proportion formula:

= (20 x 6) / 30

Abcd is a trapezoid. = 1 cm and = 5 cm, and the area = 7.5 cm2. what is the altitude of the trapezoid? 1.5 cm 2.5 cm 3 cm 2 cm
Answer:
2.5cm
Step-by-step explanation:
hope it helps. if there's any question feel free to ask me I be ready to respond appropriately bye.
The altitude of the trapezoid is approximately 2.5 cm.
Here, we have,
To find the altitude of the trapezoid, we can use the formula for the area of a trapezoid:
Area = (1/2) * (sum of the bases) * altitude
Given that
one base (a) is 1 cm, the other base (b) is 5 cm, and the area is 7.5 cm², we can plug these values into the formula and solve for the altitude:
7.5 cm² = (1/2) * (1 cm + 5 cm) * altitude
Simplifying:
7.5 cm² = (1/2) * 6 cm * altitude
7.5 cm² = 3 cm * altitude
Now, we can isolate the altitude by dividing both sides of the equation by 3 cm:
altitude = 7.5 cm² / 3 cm
altitude ≈ 2.5 cm
Therefore, the altitude of the trapezoid is approximately 2.5 cm.

If $3700 is invested at a rate of 2.4% that is compounded annually, how much will it be worth after 4 years?
The amount the money will be worth in 4 years is $4072.41
Compound interestThe formula for calculating the compound interest is expressed as;
A = P(1+r/n)^nt
Given the following
P = $3700
rate r = 2.4% = 0.024

Substitute
A = 3700(1+0.024/12)^12(4)
A = 3700(10.024/12)^48
