Determine whether the vectors in each pair are normal to each other. (8,-4) and (-2,4)
Since their dot product is not equal to zero, then (8,-4) and (-2,4) are not normal to each other.
Two vectors are said to be normal or perpendicular to each other if the result of their dot product is equal to zero.
These two vectors are also called orthogonal to each other.
Let u = (u₁, u₂) and v = (v₁, v₂), then the dot product u . v is defined as:
u . v = u₁v₁ + u₂v₂
To check whether the vectors are normal to each other, let us check their dot product.
The given vectors are: (8,-4) and (-2,4)
Let u = (8,-4) and v = (-2,4), then,
u . v = 8 . (-2) + (-4) . 4
= -16 + (-16) = -32 (not equal to zero)
Since u.v ≠ 0, then (8,-4) and (-2,4) are not normal to each other.

Sam has three times as many crayons as Thabo. If he gives Thabo 17 crayons he will have twice as many crayons as Thabo. How many crayons did Thabo have to start with?
Answer:
Thabo had 51 crayons at the start.
Step-by-step explanation:
Sam has three times as many crayons as Thabo. Then
x = 3y.
If Sam gives 17 crayons to Thabo, then he will have twice as many crayons as Thabo. Then
(x-17) = 2(y+17).
Thabo had 51 crayons to start with.
Given that Sam has three times more crayons than Thabo does. He will have twice as many crayons as Thabo if he gives him 17 of them.
We need to determine the number of crayons Thabo had in starting.
Let's use algebra to solve this problem step-by-step.
Let's assume that Thabo starts with "x" crayons.
According to the given information:
Sam has three times as many crayons as Thabo, which means Sam has 3x crayons.
If Sam gives Thabo 17 crayons, he will have (3x - 17) crayons left.
Thabo will have (x + 17) crayons after receiving the 17 crayons from Sam.
Now, the second condition states that if Sam gives Thabo 17 crayons, he will have twice as many crayons as Thabo.
Mathematically, it can be expressed as:
2(x + 17) = 3x - 17
Let's solve this equation to find the value of x:
2x + 34 = 3x - 17
Subtract 2x from both sides:
34 = x - 17
Now, add 17 to both sides:
x = 51
So, Thabo had 51 crayons to start with.

Becuse
Answer:
80 (Estimate, we'll get to the exact result at the end.)
Step-by-step explanation:
[tex]\mathrm{(Round)~If~x < 5,~x=y.0}[/tex]
→ y is the number, for instance, 60.0 since 63.0 in the ones/tenths place is less than 5 or 0.5
[tex]20 \times 70 = 1,400[/tex]
→ imagine the newly rounded 73 as 2 × 7 which is 140, but it's 2 more 0's, so it's 1,400.
[tex]\bold{77}\\18|1,400\\18 \times 7 = 126\\140 - 126 = 14\\18 \times 7 = 126\\140 - 126 = 14[/tex]
→ long division was performed. for each time a 0 appeared in 14 when 140 was subtracted by 126(18 • 7), a zero was either borrowed from 1,400 or dropped from 1,400 which became our remainder of 14 both ways around.
→ 77 is close to 75 but not below 5, so it round to 80. therefore, your estimate result is 80.
(The exact result is 81.1)

A contractor purchases 6 dozen pairs of padded work gloves for $89.28 . He incorrectly calculates the unit price at $14.88 per pair for the expense report. What is the correct unit price? Why is the contractor's unit price incorrect?
The correct unit price is $1.24 per pair of padded gloves such that the contractor's unit price is incorrect because total cost was divided by number of dozens bought instead of the number of units in 6 dozens
How many units are in a dozen?
The dozen of pairs of padded gloves contains 6 pairs of padded gloves, in other words, the number of units in 6 dozens is 6 dozens multiplied by 12 units in a dozen
number of units in 6 dozens=6*12

The required factor for the given expression is (x + 4)(3x - 1).
In mathematics, factorization or factoring refers to the process of composing a number or other mathematical object from numerous factors, usually smaller or simpler counterparts.
The given expression is 3x² + 11x - 4.
To factor a general quadratic expression of the form ax² + bx +c, we need to consider the product "ac" and find two factors for this number such that their sum is equal to b. during this case, a = 3, b = 11, and c = -4..
Therefore we need to consider the product ac = 3 × (-4) = -12.
Consider the 2 factors 12 and -1 for the product -12.
Then we have the sum is equal to 12 + (-1) = 12 - 1 = 11.
Therefore the expression 3x² + 11x - 4= 3x² + 12x + (-1)x -4= 3x² +12x - x - 4= 3x(x + 4) - (x + 4)= (x + 4)(3x - 1)

Center = (6,15)
Radius = 2
The equation of the circle where the given parameters are Center = (6, 15) and Radius = 2 is (x - 6)^2 + (y - 15)^2 = 4
How to determine the equation of the circle?The given parameters are
Center = (6, 15)
Radius = 2
Rewrite the above parameters properly as
Center, (h, k) = (6, 15)
Radius, r = 2
The equation of the circle is represented as
(x - h)^2 + (y - k)^2 = r^2
Substitute the known values in the above equation

find the next four terms of the geometric sequence given the a1=2x r=x³
Answer: [tex]2\text{x}^4, \ 2\text{x}^7, \ 2\text{x}^{10}, \ 2\text{x}^{13}[/tex]
===========================================================
Explanation:
The first term is [tex]a_1 = 2\text{x}[/tex] and the common ratio is [tex]r = \text{x}^3[/tex]
To get the second term, we multiply the first term by that common ratio
[tex]a_2 = a_1*r = 2\text{x}*\text{x}^3 = 2\text{x}^4[/tex]
Repeat a similar idea for the third term
[tex]a_3 = a_2*r = 2\text{x}^4*\text{x}^3 = 2\text{x}^{4+3} = 2\text{x}^7[/tex]
and the fourth term is
[tex]a_4 = a_3*r = 2\text{x}^7*\text{x}^3 = 2\text{x}^{7+3} = 2\text{x}^{10}[/tex]
The fifth term is
[tex]a_5 = a_4*r = 2\text{x}^{10}*\text{x}^3 = 2\text{x}^{10+3} = 2\text{x}^{13}[/tex]
Something to notice: The exponents of the first five terms are: 1, 4, 7, 10, 13. The sequence of exponents is arithmetic even though the original underlying sequence is geometric.
The reason why the exponent sequence is arithmetic is because we keep multiplying by [tex]\text{x}^3[/tex], and hence we keep adding 3 to each exponent to get the next exponent.
-----------------------------------------
To summarize, the first five terms are:
[tex]2\text{x}, \ 2\text{x}^4, \ 2\text{x}^7, \ 2\text{x}^{10}, \ 2\text{x}^{13}[/tex]
We will ignore the first term 2x since your teacher wanted you to find the next four terms after that first term (i.e. term2 through term5).
