Answer:
The first graph.
Step-by-step explanation:
An exponential function has a graph that is a smooth curve; it either increases at an ever increasing rate or decreases at an ever increasing rate.
The only graph that fits these characteristics is the first one.
Answer:
First graph is the exponential function
Step-by-step explanation:
The x value of exponential function is all real numbers
x can take any value positive or negative numbers
In the first graph , as x value increases the graph goes down
The first graph is an exponential function .
Second graph is the cubic function as the graph goes from left and it goes down on the right .
Third graph is an rational function because we have two graph on both sides of vertical asymptote
The fourth graph is not an exponential function as the domain is not all real numbers.

To rationalize the denominator of 2/square 13+ squared 11 , you should multiply the expression by which fraction?
Answers
Answer:
You should multiply the expression by [tex]\frac{\sqrt{13}-\sqrt{11}}{\sqrt{13}-\sqrt{11}}[/tex]
Explanation:
To rationalize any expression, you must multiply it by its conjugate. A conjugate is defined as a similar expression to the original one but with an opposite sign
This means that:
The conjugate of a + b would be a - b
Now, the given expression is [tex]\frac{2}{\sqrt{13}+\sqrt{11}}[/tex]
Consider the denominator:
From the above, we can conclude that the conjugate of [tex]\sqrt{13}+\sqrt{11}[/tex] is [tex]\sqrt{13}-\sqrt{11}[/tex]
And, remember that we need to keep the value of the expression unchanged. This means that we must multiply both the numerator and the denominator by the same value
Therefore:
You should multiply the expression by [tex]\frac{\sqrt{13}-\sqrt{11}}{\sqrt{13}-\sqrt{11}}[/tex] in order to rationalize the denominator
Hope this helps :)
Answer:
[tex] \frac { \sqrt { 13 } - \sqrt { 11 } } { \sqrt { 13 } - \sqrt { 11 } } [/tex]
Step-by-step explanation:
We are given the following expression and we are to determine the expression that we need to multiply it with in order to rationalize the denominator:
[tex] \frac { 2 } { \sqrt { 13 } + \sqrt { 11 } } [/tex]
To rationalize its denominator, we must multiply it with its conjugate.
For the denominator of the given expression, its conjugate would be [tex] \sqrt { 13 } - \sqrt { 11 } [/tex].
So to rationalize the expression, we would multiply it with:
[tex] \frac { \sqrt { 13 } - \sqrt { 11 } } { \sqrt { 13 } - \sqrt { 11 } } [/tex]

you are making a fresh fruit salad using cantaloupe how much cantaloupe (AP) would you have to order if you needed 15 pounds (EP) and if canaloupe has a 55 percent yield?
Answers
Answer:
You would need to order 28 pounds. (27.27...)
Step-by-step explanation:
Let x be the number of cantaloupe. Then, 0.55x-=15.
0.55x=15
55x=1500
11x=300
x=300/11
x=27.27...
To make fruit salad using cantaloupe, you would need to order 28 pounds (AP) if you only need 15 pounds (EP) and the cantaloupe has a 55% yield.
Explanation:To determine how much cantaloupe (AP) you would need to order, you need to consider the yield percentage. If the cantaloupe has a 55% yield, it means that 55% of the cantaloupe will be usable. So, you need to order more than 15 pounds (EP) to account for the reduced yield.
To calculate the amount of cantaloupe (AP) to order, you can use the formula:
AP = EP / Yield Percentage
Using the given values, the calculation would be:
AP = 15 pounds / 55% = 27.27 pounds
Rounded up to the nearest whole number, you would need to order 28 pounds of cantaloupe (AP) to obtain 15 pounds (EP) with a 55% yield.

The graph models which linear equation?
3x + 5y = 10
v-2x-2
3x - 5y = 10
Answers
Answer:
a
Step-by-step explanation:
Based on the slope and y-intercept, the graph most closely models the linear equation 3x + 5y = 10.
Out of the three choices you provided, the graph most closely resembles the equation 3x + 5y = 10. Here's why:
Slope: The slope of the line in the graph is positive. This means that as x increases, y also increases. The equation 3x + 5y = 10 has a positive slope of [tex]$\dfrac{3}{5}$[/tex], which matches the slope of the line in the graph.Y-intercept: The y-intercept of the line in the graph is 2. This means that the line passes through the point (0, 2). When you plug x = 0 into the equation 3x + 5y = 10, you get 5y = 10, which means y = 2.So, the equation 3x + 5y = 10 also has a y-intercept of 2.
The other two equations do not match the graph as well:
The equation v - 2x - 2 does not have a positive slope.The equation 3x - 5y = 10 has a negative slope and a different y-intercept.Write an algebraic expression for “12 less than the quotient of 12 and a number z.”

If the sum of two congruent lengths equal the length of a third side,then the triangle created is isosceles. Is this a true statement?
Answers
Answer:
False
Step-by-step explanation:
To form a triangle, the sum of any two sides must be LARGER than the length of the third side.
This question says the sum of two sides are equal to the length of the third side. This wouldn't form a triangle.
Final answer:
Yes, the statement is true. If the sum of two congruent lengths is equal to the length of a third side in a triangle, then the triangle is isosceles.
Explanation:
Yes, the statement is true. If the sum of two congruent lengths is equal to the length of a third side in a triangle, then the triangle is isosceles.
In an isosceles triangle, two sides have the same length (congruent sides) and the remaining side is different (non-congruent side).
For example, if we have a triangle ABC where AB = BC (congruent sides) and AC is a different length (non-congruent side), then the triangle ABC is isosceles.

Solve. 90^x = 27. Explain every step.
Answers
Answer:
The answer is ⇒ x = 0.73244
Step-by-step explanation:
∵ 90^x = 27 ⇒ insert log in both sides
∴ [tex]log(90)^{x}=log(27)[/tex]
∵ 90 = 9 × 10 , 27 = 3³
∵ log(a)^b = b log(a)
∴ log(9 × 10)^x = x log(9 × 10)
∴ [tex]xlog(9*10)=log(3^{3})[/tex]
∵ log(a × b) = log(a) + log(b)⇒log(9 × 10) = log(9) + log(10)
∴ [tex]x[log(9)+log(10)]=3log(3)[/tex]
∵ log(10) = 1 , 9 = 3²
∴ [tex]x[log(3)^{2}+1]=3log(3)[/tex]
∴ [tex]x[2log(3)+1] = 3log(3)[/tex]
∴ x = (3log3)/[2log(3)+1]
∴ x = 0.73244
ANSWER

EXPLANATION
The given exponential equation is
[tex] {90}^{x} = 27[/tex]

[tex] ln( {90}^{x} ) = ln(27) [/tex]
Recall and the following property of logarithms.
[tex] ln( {a}^{n} ) = n \: ln(a) [/tex]
This implies that;
[tex]x ln(90) = ln(27) [/tex]
Solve for x.

See an algebraic equation to solve the problem. The sides of a triangle are in the ratio 3 : 4 : 5. What is the length of each side if that perimeter of the triangle is 90 cm?
Answers
Answer:
22.5
30
37.5
Step-by-step explanation:
You have to multiply each ratio part by x to get them properly set up to add to 90.
3x + 4x + 5x = 90 Combine the left side
12x = 90 Divide by 12
12x/12 =90/12 Do the division
x = 7.5
3x = 3*7.5 = 22.5
4x = 4*7.5 = 30
5x = 5*7.5 = 37.5
Total 90
Final answer:
The lengths of the sides of the triangle with a perimeter of 90 cm and sides in the ratio 3:4:5 are 22.5 cm, 30 cm, and 37.5 cm. This is found by setting up an equation with variable x representing the common multiplier for the ratio, solving for x, and then calculating each side's length.
Explanation:
To solve the problem of finding the length of each side of a triangle with sides in the ratio 3:4:5 and a perimeter of 90 cm, we first set up an algebraic equation. Let the sides of the triangle be 3x, 4x, and 5x, respectively. The perimeter is the sum of these sides, so we have the equation 3x + 4x + 5x = 90 cm. Simplifying this gives us 12x = 90 cm. To find the value of x, we divide both sides of the equation by 12, resulting in x = 90 cm / 12, which simplifies to x = 7.5 cm. Subsequently, the lengths of the sides are 3x = 22.5 cm, 4x = 30 cm, and 5x = 37.5 cm.
