Answer:
BC ≈ 15.01
Step-by-step explanation:
Using the tangent ratio in the right triangle
tan65° = [tex]\frac{opposite}{adjacent}[/tex] = [tex]\frac{BC}{AC}[/tex] = [tex]\frac{BC}{7}[/tex] ( multiply both sides by 7 )
7 × tan65° = BC , then
BC ≈ 15.01 ( to the nearest hundredth )

By definition of exponential function, The function y = (1/5)ˣ is an exponential decay.
What is mean by Function?A relation between a set of inputs having one output each is called a function. and an expression, rule, or law that defines a relationship between one variable (the independent variable) and another variable (the dependent variable).
We have to given that;
The function is,
⇒ y = (1/5)ˣ
Now, We have;
The general form of the exponential function is,
⇒ y = a bˣ
If b < 1 , function is an exponential decay.
If b > 1, function is an exponential growth.
Here, The function is,
⇒ y = (1/5)ˣ
And, b = 1/5 < 1
Hence, By definition of exponential function, The function y = (1/5)ˣ is an exponential decay.
Therefore, By definition of exponential function, The function y = (1/5)ˣ is an ''exponential decay.''

The length of other leg of a right triangle is 6.633 cm
What is a right triangle?A triangle in which one of the interior angles is 90° is called a right triangle. The longest side of the right triangle, which is also the side opposite the right angle, is the hypotenuse and the two arms of the right angle are the height and the base.
To find the length of hypotenuse the formula is c² =a² + b² , where c is hypotenuse and a, b are sides of triangle
From the question hypotenuse(c)= 12 cm and one of its leg(b) =10cm
12² =a² +10²
144= a² + 100
44= a²
a= 6.633
Thus the length of other leg of a right triangle is 6.633 cm

Dakota paid $48.60 for a new backpack, and this included an 8% sales tax. What is the price before tax.
Answers
Answer:
The price before sales tax was added was $9.72.
Step-by-step explanation:
48.60 x 0.8 = 38.88 (Sales tax price)48.60 - 38.88 = 9.72 (Price before sales tax)find the angles of a cyclic quadrilateral ABCD in Angle A = (4x+20 )^0 , Angle B = (3x+5 )^0 , Angle C =(4y)^0 , Angle D = (7y-5)^0
Answers
Answer:
<A = 120degrees
<B = 80degrees
<C = 60degrees
<D = 100degrees
Step-by-step explanation:
For a cyclic quadrilateral, the sum of the adjacent angle of the quadrilateral are equal, hence;
<A + <C = 180
<B + <D = 180
Substitute the given values
4x+20+4y = 180
4x+4y =1 60
x + y = 40 ...1
Similarly;
3x+5+7y - 5 = 180
3x+7y = 180 ....2
Solving simultaneously
x + y = 40 ...1 .....* 3
3x+7y = 180 ....2 ...... *1
__________
3x + 3y = 120 ...1 .
3x+7y = 180 ....2
Subtract
3y - 7y = 120 - 180
-4y = -60
y = 15
Since x+y = 40
x + 15 = 40
x = 40 - 15
x = 25
<A = 4x+20
<A = 4(25)+20
<A = 120degrees
<C = 180 - <A
<C = 180 - 120
<C = 60degrees
<B = 3x+5
<B = 3(25)+5
<B = 80degrees
<D = 180 - <B
<D = 180 - 80
<D = 100degrees
