Step-by-step explanation:
a) A robot can complete 7 tasks in 3/5 hours.
This means ;
7 tasks = 3/5 hours
1 task = ?
perform cross- multiplication as;
{1*3/5} /7
3/35 hours
b)
3/5 hours = 1 task
1 hour = ?
{1*1} / 3/5
1 / 3/5

Which expression is equivalent to cos(3x) sin x?
Answer:
[tex]\frac{1}{2} [sin(4x)-sin(2x)][/tex]
Step-by-step explanation:
Use the Product-Sum identity to turn cos(3x) sin x into a sum.
Formula: cos(u) + sin(v) = [tex]\frac{1}{2}[sin(u+v)-sin(u-v)][/tex]
Plug 4x and 2x for u and v into the formula: [tex]\frac{1}{2}[sin(3x+x)-sin(3x-x)][/tex]
Simplify: [tex]\frac{1}{2}[sin(4x)-sin(2x)][/tex]
:)
The expression is equivalent to cos(3x) sin x will be 1/2 [sin (4x ) - sin (2x)].
What are equivalent expressions?Those expressions who might look different but their simplified forms are same expressions are called equivalent expressions.
Formula we will use;
cos(u) + sin(v) = 1/2 [sin (u +v ) - sin (u - v)]
Now, Plug 4x and 2x for u and v into the formula:
1/2 [sin (3x + x ) - sin (3x - x)]
Simplify:
1/2 [sin (4x ) - sin (2x)]

Solve the linear equation 2.25 - 11j - 7.75 + 1.5j = 0.5j - 1
2.25 - 11j - 7.75 + 1.5j = 0.5j - 1
(2.25 - 7.75) + (-11j + 1.5j) = 0.5j - 1
-5.5 -9.5j = 0.5j - 1
-9.5j -0.5j = -1 + 5.5
-10j = 4.5
j = 4.5/-10
j = -0.45
Answer:
A. j=-0.45

A)x= -5,3
B)x= 5,3
C)x= -5 -3
D)x= 5,-3
Answer:
The answer is A.
Step-by-step explanation:
Let's solve your equation step-by-step.
x2+2x−15=0
Step 1: Factor left side of equation.
(x−3)(x+5)=0
Step 2: Set factors equal to 0.
x−3=0 or x+5=0
x=3 or x=−5
Answer:
x=3 or x=−5
The solutions of the given quadratic equation are x=-5 and x=3. Therefore, option A is the correct answer.
What is the solution of a quadratic equation?The solutions to the quadratic equation are the values of the unknown variable x, which satisfy the equation. These solutions are called roots or zeros of quadratic equations. The roots of any polynomial are the solutions for the given equation.
The given quadratic equation is x²+2x-15=0.
By using splitting middle term method, we get
x²+5x-3x-15=0
x(x+5)-3(x+5)=0
(x+5)(x-3)=0
x+5=0 and x-3=0
x=-5 and x=3

Anyoneee?? Mean Median and mode
Answer:
mode is the most occuring number which is in this case 11
you get the median by putting them in order from least to greatest and them marking them out until you get to the middle but if there are two numbers in the middle you add them and then divide by two and that is your median but in this case your median is 11
you get the mean by adding all the numbers together and dividing by how many numbers there are so in this case you are dividing by 9 and when you add oall of these numbers together you get 98 and 98/9 is 10.8888888889 which you would round and get 10.9

Answer:
The ranges of the value can be from 12-24
Step-by-step explanation:
Hope this helps <3
Tell me if you want an explanation.
Answer:
17cm
Step-by-step explanation:
We are given two sides, so we can use the Pythagorean theorem [ a² + b² = c² ] to solve for the third side. Let a = 6 and c = 18.
6² + b² = 18²
36 + b² = 324
b² = 288
√b² = √288
b ≈ 17cm

Bill can make 400 sandwiches in 2 ½ hours. What is his unit rate?
Answer:
160 sandwiches/hour
Step-by-step explanation:
To find his unit rate, divide 400 by 2.5, since he can make 400 sandwiches in 2.5 hours:
400/2.5
= 160
This means he can make 160 sandwiches in 1 hour.
So, his unit rate is 160 sandwiches/hour
