cot^2x-csc^2x=
please include the steps thank you !!
will give branliest
Answer:
Step-by-step explanation: One of the fundamental identities is #1+cot^2(x) = csc^2(x)#.
Starting with your given:
#cot^2(x)-csc^2(x)#
Replace #csc^2(x)# with #1+cot^2(x)#:
#cot^2(x)-(1+cot^2(x))#
#=cot^2(x)-1-cot^2(x))#
#=-1#

Is y = 5(1.04)* A. growth or B. decay?
Answer:
growth
Step-by-step explanation:
Answer:
A. Growth
Step-by-step explanation:
There is a 1 in front of 0.04, which also means 104%, so it's an increase, therefore growth. Decay would be below 100%.

One week, seventy-two percent of the animals that came to a veterinary hospital were dogs. If there were 230 animals total, how many were dogs?
Answer:
166 dogs were at the veterinary hospital
Step-by-step explanation:
Here, we want to know the number of dogs that were at the veterinary hospital
From the question, 72% of these animals are dogs
72% of a total of 230
Mathematically, the number of dogs are as follows;
dogs = 72% of 230
dogs = 72/100 * 230 = 165.6
since we cannot have a fractional dog, we round off to the nearest whole number which is 166 dogs

Answer:
-15 + -3 = -18
Rob owes his father $18.
Step-by-step explanation:
Rob has to pay back the same amount of money that he took. Since he took 15 dollars, he has to give back 15 dollars which makes the 15 negative. The same goes for the 3 in the equation.
To find out the total amount Rob has to pay back, we have to add -15 and -3, which is -18.
Which graph shows a linear function?
Answer:
There is no graph but the graph that would have a straight line
Answer:
Whichever line is straight and does not have x repeat itself is considered linear.
Step-by-step explanation:
A linear function can be shown by using the equation y=mx+b, in which m is the slope and b is the y-intercept. A linear function must be able to follow this formula in order to be considered linear. An exponential equation, quadratic equation, or other equation will not work.
Chances are, if the line is straight and the points plotted can be connected within a straight line and not overlap, they are a linear function.
[A function being an equation in which x does not repeat itself, therefore a vertical line up and down is not considered a linear function, however, a horizontal line is.]

Answer:
$13.76
Step-by-step explanation:
Cost at store A = $29.35
Cost at store B = $32.79
Difference in price at both stores :
Difference = store B - store A
Difference in price = $32.79 - $29.35 = $3.44
Extra cost to f purchasing 4 video games at store B:

The figure is made up of two cones and a cylinder. Both cones and the cylinder have a 10 mm diameter. What is the exact volume of this figure? What is the volume of this figure? A.250(pi)mm³
B.4007(pi)mm³
C.6257(pi)mm³
D.2500(pi)mm³
Answer:
Step-by-step explanation:
The answer choices don’t make sense. The volume of a cylinder of height 45mm and radius 5mm = π5²*45 = 1125π mm³.
Three of the answer choices are larger than 1125π.
:::::
volume of one cone = πr²h* ⅓
Volume of cylinder section = πr²h
Total volume = πr²h*⅔ + πr²h = πr²h*5/3 = π5²*15*5/3 = 625π

Find the value of x.
Answer:
50
Step-by-step explanation:
The upper left hand arc is also 130
The lower right hand arc is also x
A circle all the way around from some starting point is 360 degrees.
x + x + 130 + 130 = 360 Equation. Combine like terms.
2x + 260 = 360 Subtract 260 from both sides
2x = 360 - 260
2x = 100 Divide by 2
x = 100/2
x = 50
