Two cables are securing a kayak to a roof rack. The forces are represented by vectors Vector u = LeftAngleBracket negative 5, 6, 3 RightAngleBracket. and Vector t = LeftAngleBracket negative 8, negative 2, 1 RightAngleBracket.. If both cables are replaced by a single cable, what vector would represent the cable?
LeftAngleBracket 3, 8, 2 RightAngleBracket.
LeftAngleBracket negative 13, 4, 4 RightAngleBracket.
LeftAngleBracket negative 3, negative 8, negative 2 RightAngleBracket.
LeftAngleBracket 13, negative 4, negative 4 RightAngleBracket.
Answer:
< –13, 4, 4 >
Step-by-step explanation:
Vector u = < –5, 6, 3 >
Vector t = < –8, –2, 1 >
-5 6 3
+ -8 -2 1

A table showing Tickets Sold, Cost, and Total. The first row shows Child, with the entries, c, 3, and 3 c. The second row shows Adult, with entries, x, 5, 5 x. The last row shows Total, with all three entries blank.
Tickets to a baseball game cost $3 for a child’s ticket and $5 for an adult ticket. At the last game, $521 was collected when 139 people attended the game. Which value could replace x in the table so that a single-variable equation can be written and solved to determine the number of child’s tickets, c, sold?
Answer:
x = 52, c = 87
Step-by-step explanation:
Set up and then solve this system of equations:
3c + 5x = 521--->3c + 5x = 521
c + x = 139 --->3c + 3x = 417
-------------------
2x = 104
x = 52, c = 87
Answer: the answer is 139-c

if you help it would be appreciated
#learning with brainly
Answer:
25 fl oz
Step-by-step explanation:
1 pint is equivalent to 16 fl oz, so we're left with 25 fl oz and 16 fl oz. As you can see, 25 is greater than 16, making 25 fl oz the correct answer.
Distance between -3,-2 and 5,2
We can find the distance between two points by using distance formula,
[tex] \qquad \: D = \sf \red{\sqrt{ {(x_2 -x_1)}^{2} + {(y_2 -y_1)}^{2} }}[/tex]
Here,
x₁ = -3
x₂ = 5
y₁ = -2
y₂ = 2
Therefore,
[tex] : \implies \: D = \sf \red{\sqrt{ {(x_2 -x_1)}^{2} + {(y_2 -y_1)}^{2} }} \\ \\ : \implies \: D = \sf \sqrt{ {(5-( - 3))}^{2} + {(2 -( - 2))}^{2} }
\\ \\ : \implies \: D = \sf \sqrt{ {8}^{2} + {4}^{2} } \\ \\ : \implies \: D = \sqrt{64 + 16}
\\ \\ : \implies \: D = \sqrt{80} [/tex]
Hence the √80 = 8.94 approx is the distance between the two points (-3,-2) and (5,2).
To find :-
The distance between 2 points
Given :-Here we have been provided 2 points
(-3, -2) and (5, 2)
Solution :-[tex] (x_1,y_1) = (-3,-2) \\ (x_2,y_2) = (5,2) [/tex]
Formula to find distance is
[tex] = \sqrt{ {(x_2 - x_1)}^{2} + {(y_2 - y_1)}^{2} } [/tex]
[tex] = \sqrt{ {(5 - ( - 3))}^{2} + {(2 - ( - 2))}^{2} } \\ = \sqrt{ {(8)}^{2} + {(4)}^{2} } \\ = \sqrt{64 + 16} \\ = \sqrt{80} \\ = 4 \sqrt{5} [/tex]
Result :-The distance between 2 points is 4√5.

There are 114 cans of soup in a grocery store. The ratio of large cans of soup to small cans of soup is 12:7. A customer buys 2 large cans of soup. What is the new ratio of large cans of soup to small cans of soup in the grocery store? Choose all the correct answers. A. 3:5 B. 5:3 C. 8:5 D. 10:7 E. 35:21 F. 37:21
The ratio of the large cans to small cans shows the distribution of both cans
The new ratio of large cans of soup to small cans of soup in the grocery store is (b) 5 : 3 and (e) 35: 21
How to determine the ratio?The given parameters are:
Ratio = 12 : 7
Rewrite as:
Large : Small= 12 : 7
The number of cans is given as:
Can = 114
So, the distribution of the cans are:
Large = 12/(12 + 7) * 114
Large = 72
Small = 7/(12 + 7) * 114
Small = 42
When 2 large cans are purchased, the remaining number of cans are:
Small = 42
Large = 70
Express as ratio
Large : Small = 70 : 42
Simplify
Large : Small = 35 : 21
Large : Small = 5 : 3
Hence, the new ratio is (b) 5 : 3 and (e) 35: 21

4. 2[tex]x^{7}[/tex] + [tex]x^{6}[/tex] - 28[tex]x^{5}[/tex] + 3x + 12
Step-by-step explanation:
To multiply polynomials, simply distribute whatever's outside the largest set of parenthesis, then combine like terms.
1) Distribute the parenthesis (x + 6):
x(4x² + 2x - 8) + 6(4x² + 2x - 8)
4[tex]x^{3}[/tex] + 2x² -8x + 6(4x² + 2x -8)
4[tex]x^{3}[/tex] + 2x² -8x + 24x² + 12x - 48
Combine like terms:
4[tex]x^{3}[/tex] + 26x² + 4x - 48
2) Distribute the parenthesis (x - 8):
x(2x² - 7x + 4) + (-8)(2x² - 7x + 4)
2[tex]x^{3}[/tex] - 7x² + 4x + (-8)(2x² - 7x + 4)
2[tex]x^{3}[/tex] - 7x² + 4x + -16x² + 56x - 32
Combine like terms:
2[tex]x^{3}[/tex] - 23x² + 60x - 32
3) Distribute the parenthesis (x + 2):
x([tex]x^{4}[/tex] + 7x² - 4) + 2([tex]x^{4}[/tex] + 7x² - 4)
[tex]x^{5}[/tex] + 7[tex]x^{3}[/tex] - 4x + 2([tex]x^{4}[/tex] + 7x² - 4)
[tex]x^{5}[/tex] + 7[tex]x^{3}[/tex] - 4x + 2[tex]x^{4}[/tex] + 14x² - 8
No like terms to combine, so:
[tex]x^{5}[/tex] + 7[tex]x^{3}[/tex] - 4x + 2[tex]x^{4}[/tex] + 14x² - 8
4) Distribute the parenthesis (x + 4):
x(2[tex]x^{6}[/tex] - 7[tex]x^{5}[/tex] + 3) + 4(2[tex]x^{6}[/tex] - 7[tex]x^{5}[/tex] + 3)
2[tex]x^{7}[/tex] - 7[tex]x^{6}[/tex] + 3x + 4(2[tex]x^{6}[/tex] - 7[tex]x^{5}[/tex] + 3)
2[tex]x^{7}[/tex] - 7[tex]x^{6}[/tex] + 3x + 8 [tex]x^{6}[/tex] - 28[tex]x^{5}[/tex] + 12

graph of F(x), shown below, has the same shape as the graph of G(x) = x4, but it is shifted 4 units to the right. What is its equation?F(x) = _____
Answer:

Step-by-step explanation:
The equation of the graph of f(x) which is formed by shifting 4 units to the right of g(x) is f(x) = (x - 4)⁴
What is Translation of Functions?Translation of functions is defined as the when each point in the original graph is moved by a fixed units in the same direction.
There are horizontal translation and vertical translation of functions.
Given a function G(x).
G(x) = x⁴
A function F(x) is formed by shifting the graph of G(x) to the right by 4 units.
A function h(x) when shifted to the right by k units becomes h(x - c).
So the graph of G(x) when shifted to the right by 4 units becomes G(x - 4).
G(x - 4) = (x - 4)⁴
So, F(x) = (x - 4)⁴
Hence the function is F(x) = (x - 4)⁴.
