Find the perimeter of this shape
Answer:
the answer is 58
Step-by-step explanation:
first rectangle is 6 by 10
and second rectangle is 7 by 16
perimeter (2*(16+7))+(2*(10+6))=78 ××
edite:
sorry i made a mistake the real answer is 58 because we add all the sides together 16+13+10+6+6+7=58
have a nice day :)
Hello!
The perimeter is sum of all sides of a figure. In this figure, we have unknown sides. To find the unknown sides, we have to use the sides that we know. By adding and subtracting numbers, you can find the other sides. See the image below, to see how I did it.
I also have another practice problem, for you to practice on your own if you want to.
Also, mishap on picture, The answer is 58.
If the point (3,5)is on the graph of a function f, then f(…….)=
Answer:
Step-by-step explanation:
A point (a,b) is on the graph of y = f(x) whenever we plugin x = a and y = b to the equation we have a true statement.
Since (3,5) is on the graph then f(3) = 5.
SImilarly since g (-6) =2 , then (-6, 2) is on the graph of g.

A survey of 1,095 tourists visiting Orlando was taken. Of those surveyed:
295 tourists had visited the Magic Kingdom
290 tourists had visited LEGOLAND
280 tourists had visited Universal Studios
66 tourists had visited both the Magic Kingdom and LEGOLAND
68 tourists had visited both the Magic Kingdom and Universal Studios
51 tourists had visited both LEGOLAND and Universal Studios
18 tourists had visited all three theme parks
How many tourists had not visited any of these three theme parks?
Answer:
27 tourists didn't visit those theme parks
Step-by-step explanation:
Add them all together and the sum will be 1068. Now take 1095 and subtract that 1068. The answer will be 27, meaning 27 tourists didn't go to those parks.

Thirteen less than twice a number is seventeen more than half the number. What is the number?
Answer:
20
Step-by-step explanation:
2x-13 = x/2 +17
add -x/2
2x-x/2-13=x/2-x/2+17
2x-x/2 -13=17
add 13
2x-x/2 -13+13 =17+13
3x/2 = 30
multiply by 2
3x=2*30
divide by 3
x= 60/3
x=20
Answer:
Number is 4
Step-by-step explanation:
Let the number be x
2x - 13 = x/2 + 17
2x - 13 = x + 34/2
2(2x - 13) = x + 34
4x - 26 = x + 34
4x - x = 34 - 26
3x = 12
x = 12/3
x = 4
Determine the distance between the two points (-1,4) and (7,10).
The distance between the points is
Answer:
10
Step-by-step explanation:
The formula for distance is [ √(x2 - x1)^2 + (y2 - y1)^2 ]
√(7 - (-1))^2 + (10 - 4)^2
√(8)^2 + (6)^2
√64 + 36
√100

Answer:
C. angle 7
Step-by-step explanation:
...............
dados os vetores u = (2, -3, -1) e v = (1, -1, 4) o resultado de (u + v) x ( u - v) é igual a?
The cross product distributes over sums, so we have
[O produto cruzado distribui somas, então temos]
(u + v) × (u - v) = (u × u) + (v × u) + (u × (-v)) + (v × (-v))
(u + v) × (u - v) = (u × u) + (v × u) - (u × v) - (v × v)
The cross product of a vector with itself is the zero vector, so
[O produto vetorial de um vetor com ele mesmo é o vetor zero, então]
(u + v) × (u - v) = 0 + (v × u) - (u × v) - 0
(u + v) × (u - v) = (v × u) - (u × v)
The cross product is anticommutative, meaning that for two vectors u and v,
[O produto vetorial é anticomutativo, o que significa que para dois vetores u e v,]
u × v = - (v × u)
So we end up with
[Então acabamos com]
(u + v) × (u - v) = (v × u) + (v × u)
(u + v) × (u - v) = 2 (v × u)
Given that u = (2, -3, -1) and v = (1, -1, 4), compute the cross product as follows:
[Dados esses vetores, calcule o produto vetorial:]
(1, -1, 4) × (2, -3, -1)
= ((1, 0, 0) - (0, 1, 0) + 4 (0, 0, 1)) × (2 (1, 0, 0) - 3 (0, 1, 0) - (0, 0, 1))
= 2 (1, 0, 0) × (1, 0, 0) - 2 (0, 1, 0) × (1, 0, 0) + 8 (0, 0, 1) × (1, 0, 0)
… … - 3 (1, 0, 0) × (0, 1, 0) + 3 (0, 1, 0) × (0, 1, 0) - 12 (0, 0, 1) × (0, 1, 0)
… … - (1, 0, 0) × (0, 0, 1) + (0, 1, 0) × (0, 0, 1) - 4 (0, 0, 1) × (0, 0, 1)
Recall the definition of the cross product:
[Lembre-se da definição de produto vetorial:]
(1, 0, 0) × (0, 1, 0) = (0, 0, 1)
(0, 1, 0) × (0, 0, 1) = (1, 0, 0)
(0, 0, 1) × (1, 0, 0) = (0, 1, 0)
The product reduces to
[O produto se reduz a]
(1, -1, 4) × (2, -3, -1)
= -2 (0, 1, 0) × (1, 0, 0) + 8 (0, 0, 1) × (1, 0, 0)
… … - 3 (1, 0, 0) × (0, 1, 0) - 12 (0, 0, 1) × (0, 1, 0)
… … - (1, 0, 0) × (0, 0, 1) + (0, 1, 0) × (0, 0, 1)
= 2 (0, 0, 1) + 8 (0, 1, 0) - 3 (0, 0, 1) + 12 (1, 0, 0) + (0, 1, 0) + (1, 0, 0)
= - (0, 0, 1) + 9 (0, 1, 0) + 13 (1, 0, 0)
= (13, 9, -1)
Finally,
[Finalmente,]
(u + v) × (u - v) = 2 (13, 9, -1) = (26, 18, -2)

If (5^4)m = 5^12, what is the value of m? (4 points)
A. 2
B. 3
C. 5
D. 8
Answer:
The value of m is 3
Step-by-step explanation:
(5^4)m =5^12
M = 3
(5^4)3 =5^4*3=12
(5^4)3 = 5^12
Answer:
(5 ^4)^m = (5)^12
625^m = (5)^12
Taking logs of both sides
log(625) *m = log (5) *12
m = log (5) *12 / log(625)
m = 0.69897000434 * 12 / log (625)
m = 0.69897000434 * 12 / 2.7958800173
m = 0.69897000434 * 12 / 2.7958800173
m = 3 answer is B

midpoint is (2, -3 )
Step-by-step explanation:
The midpoint can be found with the formula {(x1+ x2 )/2, (y1 + y2.)/2.} ( x1 , y11 ), and (x2 , y 2 ) are the coordinates of two points, and the midpoint is a point lying equidistant and between these two points.
