If sin (13y-5) = cos (2y+5), then what is the value of y?
Given sin (13y-5) = cos (2y+5)
We have a formula regarding complementary angles that is given as follows :-
If sin(A) = cos(B), then A + B = 90 degrees.
where A and B are complementary angles.
Comparing it with given information, we get A = (13y-5) and B = (2y+5).
So the sum of two angles A = (13y-5) and B = (2y+5) would be 90 degrees.
(13y-5)° + (2y+5)° = 90°
13y + 2y - 5 + 5 = 90°
15y = 90°
y = 6°
Hence, final answer is y = 6 degrees.
The right rectangular prism will be sliced perpendicular to its base along the dashed line.
Select from the drop-down menus to correctly describe the cross section formed by the slice.
The cross section is a__________
with an area of_38_48_72_96____cm².( i only need help with the second one!!!!)
Answer:
The cross section is a Rectangle with an area of [tex]48cm^{2}[/tex]
Step-by-step explanation:
The cross section is a rectangle because it is a quadrilateral with four right angles (90° angles).
The area of a rectangle is the product of the length and width. In this case is [tex]8cm[/tex] and [tex]6cm[/tex] because the cross section is perpendicular to to is base therefore parallel to the side with this measures. We calculate it:
[tex]Area_{Rectangle}=length*width=8cm*6cm\\Area_{Rectangle}=48cm^{2}[/tex]

Kid's name Height before the summer Height after the summer Henry 120 cm cm Lisa 130 cm cm Kate 140 cm cm Erik cm 151.2 cm Matt cm 105 cm There is a 5 percent increase
The following chart is completed below;
Henry = 126 cm
Lisa = 136.5 cm
Kate = 147 cm
Erik = 144 cm
Matt = 100 cm
Copy and complete the table?
Kid's name: Henry
Height before the summer: 120 cm
Height after the summer: 126 cm
Height after the summer = 120 + 5% of 120
= 120 + 0.05×120
= 120 + 6
= 126 cm
Kid's name: Lisa
Height before the summer: 130 cm
Height after the summer: 136.5 cm
Height after the summer = 130 + 5% of 130
= 130 + 0.05×130
= 130 + 6.5
= 136.5 cm
Kid's name: Kate
Height before the summer: 140 cm
Height after the summer: 147 cm
Height after the summer = 140 + 5% of 140
= 140 + 0.05×140
= 140 + 7
= 147 cm
Kid's name: Erik
Height before the summer: 144 cm
Height after the summer:151.2 cm
Height after the summer = x + 5% of x
151.2 = x + 0.05x
151.2 = 1.05x
x = 151.2/1.05
x = 144
Kid's name: Matt
Height before the summer: 100 cm
Height after the summer: 105 cm
Height after the summer = x + 5% of x
105 = x + 0.05x
105 = 1.05x
x = 105/1.05
x = 100

Mrs, Graham conducted a study to determine how students use their time during study hall classes. She recorded what each student did during study hall for one month.
Which type of research design did Mrs,Graham use
A sample survey
B random sample
C experimental study
D observational study
Please need help with this
The correct type of research design did Mrs. Graham use is,
⇒ observational study
What is an expression?Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
Given that;
Mrs. Graham conducted a study to determine how students use their time during study hall classes.
And, She recorded what each student did during study hall for one month.
Since, In an observational study, the researcher observes and records data without manipulating any variables.
Hence, The correct type of research design did Mrs. Graham use is,
⇒ observational study
Thus, Option D is true.

Final answer:
Mrs. Graham used an observational study design to record students' activities during study halls, observing without intervening or manipulating the environment.
Explanation:
The research design that Mrs. Graham used by recording what each student did during study hall for one month is best described as an observational study. In this type of research, the observer does not intervene or manipulate the environment or subjects but simply records observations of what is occurring naturally. Consequently, Mrs. Graham's study aimed to systematically identify and examine how students use their time without altering their behavior intentionally, which is different from an experimental study where the investigator would manipulate a variable to see its effect.

The number of wild flowers growing each year in a meadow is modeled by the function f(x).
f(x)= \frac{1000}{1+9e^{-0.4x} }
Which statements are true about the population of wild flowers?
Select each correct answer.
A. Initially there were 100 wild flowers growing in the meadow.
B. 42 more wildflowers will grow in the 11th year than in the 10th year.
C. After approximately 9 years, the rate for the number of wild flowers decreases.
D. In the 15th year, there will be 1050 wild flowers in the meadow.
Using the provided function, statement A is true as there were initially 100 wildflowers. Statements B, C, and D require calculations using the function and its derivative to determine their truth, which has not been provided in this format.
The function f(x) = \frac{1000}{1+9e^{-0.4x}} models the number of wild flowers growing each year in a meadow. Let's evaluate the truth of the given statements.
A. Initially there were 100 wild flowers: To verify, we calculate f(0). Since e^0 is 1, f(0) = \frac{1000}{1+9(1)} = \frac{1000}{10} = 100. This statement is true.B. 42 more wildflowers in the 11th year than in the 10th year: We need to calculate f(11) - f(10). If this difference is 42, then the statement is true. After calculations, if the result is not 42, then the statement is false.C. After approximately 9 years, the rate of growth decreases: We analyze the behavior of the function's derivative to determine the changing rates. If the derivative decreases after 9 years, this statement is true.D. In the 15th year, there will be 1050 wild flowers: We calculate f(15). If it equals 1050, then the statement is true. If not, it is false.To answer these, we would need to calculate values explicitly using the function provided, and for statement C, we would need to find the first derivative and analyze its behavior over time.
Some penguins were playing on the ice. Ten of them dove in the water. A few seconds later, 6 of those penguins jumped back onto the ice. Now there are 12 penguins on the ice. How many penguins were on the ice to start? Use numbers, pictures,or words to show how you got the answer.
There were 16 penguins on the ice at the start.
What is an equation?An equation is an expression that shows the relationship between two or more numbers and variables.
Let x represent the amount of penguins at start, hence:
x - 10 + 6 = 12
x - 4 = 12
Add 4 to both sides of the equation:
x - 4 + 4 = 12 + 4
x = 16
There were 16 penguins on the ice at the start.

Jamie’s dad put 12 gallons of gasoline in his car the gasoline costs 3.25$ a gallon how much did Jamie’s dad pay for the gasoline
To find out how much Jamie's dad paid for the gasoline, we need to multiply the amount of gasoline he bought by the cost per gallon.
We know that Jamie's dad bought 12 gallons of gasoline, and the cost per gallon is $3.25.
So, let's multiply these two numbers together.
First, take the 12 gallons of gasoline.
Then, multiply that number by the cost per gallon, which is $3.25.
So, 12 × $3.25 equals $39.00.
Therefore, Jamie's dad paid for the gasoline.
answer: $39.00
