The value of acos(-7/6) is not a real number, we can conclude that the angle θf,g does not exist in this case.
Using the inner product =∫01f(x)g(x)dx in the vector space c0[0,1], we can find the norm of f(x) and g(x) as:
[tex]||f|| = sqrt( < f,f > ) = sqrt(∫0^1 (10x^2 - 6)^2 dx) = sqrt(680/35) = 4||g|| = sqrt( < g,g > ) = sqrt(∫0^1 (-6x - 9)^2 dx) = sqrt(405/2) = 9/2[/tex]
To find the angle θf,g between f(x) and g(x), we first need to find <f,g>:
[tex]< f,g > = ∫0^1 (10x^2 - 6)(-6x - 9) dx = -105/5 = -21[/tex]
Then, using the formula for the angle between two vectors:
cos(θf,g) = <f,g> / (||f|| ||g||) = -21 / (4 * 9/2) = -21/18 = -7/6
Taking the inverse cosine of both sides gives:
θf,g = acos(-7/6)
Since the value of acos(-7/6) is not a real number, we can conclude that the angle θf,g does not exist in this case.

Answer:
y=-9/2x-10
Step-by-step explanation:
m=(y2-y1)/(x2-x1)
m=(-1-8)/(-2-(-4))
m=-9/(-2+4)
m=-9/2
y-y1=m(x-x1)
y-8=-9/2(x-(-4))
y-8=-9/2(x+4)
y=-9/2x-36/2+8

The ratio of containers of orange juice to containers of grape juice in a store is 5 orange juices to 4 grape juices. If there are 405 containers in the store, how many are grape juice?
Answer: There are 180 grape juice in the store
Step-by-step explanation:
The ratio of containers of orange juice to containers of grape juice in a store is 5 orange juices to 4 grape juice which can be expressed as 5:4
Total number of containers = 405
total ratio = 4+5 =9
The number of containers that are orange juice = 5/9 x 405
=5 x 45=225
The number of containers that are grape juice will now be = 4/9 x 405
=4 x 45= 180.
Find the roots of the equation: f(x)=64x2+6=31
Answer:
5/8, -5/8
Step-by-step explanation:
64x^2 = 25
divide both sides by 64
x^2 = 25/64
take the square root of both sides, and the negative square roots
Answer:
x = 5/8=0.625 and x = -5/8=−0.625
Step-by-step explanation:
f(x)=64x^2+6=31
Subtract 6 from both sides.
64x^2+6=31
Subtract 6 from 31 to get 25.
64x^2=25
Divide both sides by 64.
x^2=25/64
Take the square root of both sides of the equation.
x=5/8=0.625
x=-5/8=−0.625

Please help explain. I’ve came up with 3 wrong answers
Answer:
step 1. The volume of a cylinder (V) = (pi)R^2(h).
step 2. if the volume of a similar cylinder is 88ft^3 with R =2ft
step 3. then the cylinder with R = 5 would be (5/2)^2 bigger.
step 4. the volume of figure A is 88(5/2)^2
step 5. V = 88(5/2)^2 = 550ft^3.
A 1kg book is lifted 2m. How much work was done?
Answer:
work= force ×distance
force= mass × acceleration due to gravity
mass= 1kg
acceleration=10
Force=1×10=10N
Work=10×2=20joules
The work done is 20 joule.
What is Work done?
It should be converted to energy in order to move an object. Energy can be transferred by the use of force. Work done refers to the amount of energy used by a force to move an object.
Given:
mass, m= 1 Kg
So, force = mg = 1 x 10 = 10 N
and, displacement = 2m
Now, work done= force x displacement
= 10 x 2
= 20 Joules.
Hence, the work done is 20 joule.

can someone help me find the area and perimeter please?
Answer:
Step-by-step explanation:
Remember that the formula to get the area of a right triangle is base times height divided by 2, so to find the area:
5 x 12 = 60/2 = 30
Area of this triangle is 30.
To find the perimeter, add all the sides:
5 + 12 + 13 = 30.
Perimeter of this triangle is 30.
A dealer of electric oven sold an induction heatet at Rs.4,200 with 13% VAT to a retailer. The retailer added transportation cost of Rs.250, profit 15% and local tax Rs.150 and sold to a costumer. How much will be paid for that heater if he/she has to pay 13% VAT
Answer:
$6,619.42.
Step-by-step explanation:
Since a dealer of electric oven sold an induction heater at Rs. 4,200 with 13% VAT to a retailer, and the retailer added transportation cost of Rs. 250, profit 15% and local tax Rs. 150 and sold it to a costumer, To determine how much will be paid for that heater if the consumer has to pay 13% VAT, the following calculation must be performed:
((4,200 x 1.13) x 1.15 + 250 + 150) x 1.13 = X
((4,746 x 1.15) + 250 + 150) x 1.13 = X
(5,457.9 + 400) x 1.13 = X
5,857.9 x 1.13 = X
6,619.42 = X
Thus, the price to be paid by the consumer will be $ 6,619.42.

what exactly is standard deviation? and pls gimme an example
Answer:
The standard deviation is the average amount of variability in your data set. It tells you, on average, how far each score lies from the mean.
The standard deviation measures the spread of the data about the mean value. It is useful in comparing sets of data which may have the same mean but a different range. For example, the mean of the following two is the same: 15, 15, 15, 14, 16 and 2, 7, 14, 22, 30. However, the second is clearly more spread out.
