Answer:
Sine of C=?
Among the given options which is the correct one.
Step-by-step explanation:
Consider a right-angle triangle ABC.
[tex]angle B=90^{0}[/tex]
In a right angle triangle, one angle [tex]90^{o}[/tex].
The sum of all the angles is [tex]180^{o}[/tex].
[tex]angle A +angle B+angleC=180^{0}angleA+90^{0} +angle C=180^{0}\\angleA+angleC=180^{0} -90^{0} \\angleA+angleC=90^{0} \\angleA=90^{0} -angle C[/tex]
Consider the trigonometric ratios and use the traingle ABC.
[tex]SinC=\frac{AB}{AC}[/tex]
[tex]CosA=\frac{AB}{AC}[/tex]
[tex]angleA=angle(90-C)\\Hence,\\SinC=Cos(90-C)[/tex]
Answer:
OptionF).[tex]Sine of C=Cos(90^{0} -C)[/tex]
What is the value of x?
Answer:
x = 12 degree
Step-by-step explanation:
3x + 19 + 5x = 115 degree (sum of two interior opposite angles are equal to the third side)
8x + 19 = 115
8x = 115 - 19
x = 96 /8
x = 12

Consider a function that describes how a particular car gas mileage depends on its speed. What would appropriate domain for this function?
A. 0 to 100 per hour
B. 0 to 50 miles per gallon
C. Times from 0 to 10 minutes
D. Times from -10 to 10 minutes
Answer: A. 0 to 100 per hour
==================================================
Explanation:
The phrasing "Depends on its speed" tells us that the speed is the independent variable, and therefore it's the x variable.
The domain is the set of allowed x values of a function, or allowed inputs. In this case, it appears the car's max speed is 100 mph.
Answer:
0 to 100 miles per hour
how many square feet are there in a blanket 3 feet wide and 8 feet long?
Answer:
24 sq ft
Step-by-step explanation:
Its simple! multiply length x width
length x width = area in sq ft
8 x 3 = 24 sq ft
The square feet of blanket 3 feet wide and 8 feet long is 24 sq ft.
What is the difference between length and width?When we multiply the length, width, and height of a cuboid, we obtain its volume.
Volume of Cuboid = Length x Width x Height
In other words, the capacity or volume of a cuboid or any rectangular box can be estimated if we multiply these three dimensions together.
Volume of rectangle = length x width
Area in square feet = length [tex]*[/tex] width
= 8 [tex]*[/tex] 3
= 24 sq ft
Therefore, 24 square feet are there in a blanket 3 feet wide and 8 feet long.

The distance far up the side of the house will the ladder reach now will be 15.2 feet.
The distance far up the side of the house will the ladder reach now will be 15.2 feet.
A 40 foot ladder is set against the side of a house so that it reaches up 24 feet.
What is the Pythagoras theorem?The Pythagoras theorem which is also referred to as the Pythagorean theorem explains the relationship between the three sides of a right-angled triangle. According to the Pythagoras theorem, the square of the hypotenuse is equal to the sum of the squares of the other two sides of a triangle.
Let the distance between the base of house and ladder foot is x feet.
By using Pythagoras theorem;
40² = 24² + x²
⇒ 1600 - 576 = x²
⇒ x² = 1024
⇒ x = 32 feet
If Lily grabs the ladder at its base and pulls it 4 feet farther from the house.
Then, the distance between the base of house and ladder foot = x + 5
Height of house is h feet
40² = h² + (x + 5)²
⇒ 1600 = h² + (32 + 5)²
⇒ 1600 = h² + 1369
⇒ h² = 1600 - 1369
⇒ h² = 231
⇒ h = √231
⇒ h = 15.19 feet
Therefore, the distance far up the side of the house will the ladder reach now will be 15.2 feet.

Answer: [tex]C(t) = 120(1-0.30)^t[/tex]
Step-by-step explanation:
Exponential equation for decay:[tex]y= A(1-r)^t[/tex], where A = initial value, r= decay rate , t= time.
As per given, A = 120ml , r= 0.30
[tex]C(t) = 120(1-0.30)^t[/tex]
Hence, the required function that gives the medicine's concentration in milligrams per liter, C(t), t hours after the medicine was injected.
