Sin 40=w/28
Tan 40=w/28
Cos 40 = w/28
Sin 40 = 28/w
Answer:
As we know that
tanФ = opposite ÷ adjacentTherefore, the correct ratio is:
tanФ = opposite ÷ adjacent
= w ÷ 28
= w/28
i.e.
tanФ = w/28Step-by-step explanation:
As we know that
tanФ = opposite ÷ adjacentGiven the triangle with an angle of 40°.
As the opposite of an angle 40° is the length 'w', and adjacent to the angle
40° is the length '28'.
As we know that
tanФ = opposite ÷ adjacentTherefore, the correct ratio is:
tanФ = opposite ÷ adjacent
= w ÷ 28
= w/28
i.e.
tanФ = w/28Answer:As we know that tanФ = opposite ÷ adjacentTherefore, the correct ratio is:tanФ = opposite ÷ adjacent = w ÷ 28 = w/28i.e.tanФ = w/28Step-by-step explanation:As we know that tanФ = opposite ÷ adjacentGiven the triangle with an angle of 40°.As the opposite of an angle 40° is the length 'w', and adjacent to the angle 40° is the length '28'.As we know that tanФ = opposite ÷ adjacentTherefore, the correct ratio is:tanФ = opposite ÷ adjacent = w ÷ 28 = w/28i.e.tanФ = w/28

A banner company sells 5-foot banners to retailers for x dollars. The St. James Sign Shop marks them up 90%. Express the retail price at the St. James store algebraically.
Answer:
$1.9x
Step-by-step explanation:
Given that :
Cost of banner = x dollars
Markup percentage at st. James store = 90%
Retail price at st. James store :
Initial cost + markup
Cost of banner + 90% of cost
x + 0.9x
= 1.9x
Hence, retail.price at st. James store is $1.9x
Jasmin's dog weighs 55 pounds. Her vet told her that a healthy weight for her dog would be less than or equal to 41 pounds.
Jasmin's dog can lose an average of 0.5 pounds every week. Write the solution to an inequality that describes all possible number of
weeks 2 for which her dog can be at a healthy weight.
Answer:
55-0.5x ≤ 41 (x will represent the weeks)
Step-by-step explanation:
i made x represent the weeks and we know that jasmin's dog can lose about 0.5 pound a week. and the base is 55 lbs since that is what jasmin's dog weighs. 55 minus all the weight that jasmin's dog will lose in a certain amount of weeks is the first part. then we know jasmin's dog has to be less than or equal to 41 lbs. so put that there with the less than or equal to sign.

Which is the equation of the parabola that
opens to the right, has a focus at (3.0), and
has a directrix at x=-3?
Answer:
The equation of the parabola will be:
[tex]\:y^2=12x[/tex]Step-by-step explanation:
The vertex (h, k) is halfway between the directrix and focus.
Find the x coordinate of the vertex using the formula
x = (x-coordinate of focus + directrix)/2
= (3-3)/2
= 0/2
=0
The y -coordinate will be the same as the y-coordinate of the focus.
so the vertex will be: (0, 0)
Finding the distance from the focus to the vertex
The distance from the focus to the vertex and from the vertex to the directrix is |p|.
Subtract the x coordinate of the vertex from the x -coordinate of the focus to find p .
[tex]p=3-0[/tex]
[tex]p=3[/tex]
Substitute in the known values for the variables into the equation
[tex]\left(y-k\right)^2=4p\left(x-h\right)[/tex]
[tex]\left(y-0\right)^2=4\left(3\right)\left(x-0\right)[/tex]
[tex]\:y^2=12x[/tex]
Therefore, the equation of the parabola will be:

Consider the table that includes the input and output values of a function. Which answer classifies the function using finite differences? The function is quadratic with a constant second difference of –96. The function is quadratic with a constant second difference of 96. The function is cubic with a constant third difference of –96. The function is cubic with a constant third difference of 96.
Answer:
b, quadratic with constant second difference of 96
Step-by-step explanation:
The function is cubic with a constant third difference of 96.
What is Function?A function is defined as a relation between a set of inputs having one output each. In simple words, a function is a relationship between inputs where each input is related to exactly one output.
Using differences:
X f(x) first difference second difference third
3 39 - - -
5 187 (187-39)/2= 74 - -
7 551 (551-187)/7-5 = 182 182 - 74/2 = 54 -
9 1227 (1227-551)/(9-7)=338 338-182/2=78 78-54/2 = 12
11 2311 (2311-1227)/2=542 542-338/2=102 102-78/2 = 12
According to table,
The function is cubic, because the third average change rate is constant of 12.
12>0, so the third difference is >0 then -96 is false.
Thus, the function is cubic with a constant third difference of 96.
