Convert 0.1 lb/day to oz/week
1 pound = 16 ounces
1 week = 7 days
0.1 x 7 = 0.7 pounds per week
0.7 x 16 = 11.2 ounces
0.1 lb/ day converts to 11.2 ounces / week
Is this a function please help I’m failing
Answer:
No
Step-by-step explanation:
This relation is not a function. This line has repeating x-values, it only has one so each y-value cannot have a unique x-value. For this reason, no vertical line will ever be a function.

Solve the equation in the interval [0,360). Use an algebraic method.
Answer:
70.9,109.1,204.0,336.0
Step-by-step explanation:
The solution set for the equation 6sin² θ - 7 sinθ - 5 = 0 in the interval [0,360)is {θ∈ [0,360)∣θ = 230.48 ,309.521}
What is Trigonometry?Trigonometry is a branch of mathematics that studies relationships between side lengths and angles of triangles.
The given equation is 6sin² θ - 7 sinθ = 5
Lets arrange in an order
6sin² θ - 7 sinθ - 5 = 0
a=6, b=-7 and c = -5
sinθ = 7±√49+120/12
Simplifying under the square root:
sinθ =7±17/12
Taking the positive solution first
sinθ =24/12
sinθ =2 (Not valid)
Now let's try the negative solution:
sinθ =7-17/12
sinθ =-10/12
sinθ =-5/6
θ= sin⁻¹(-5/6)
θ= −50.48⁰ ,−129.52⁰
we need to restrict our solution to the given interval [0,360), so we add 360 degrees to the negative angle:
θ=360−50.48 = 309.52 and 360 −129.52 =230.48
Therefore, the solution set for the equation 6sin² θ - 7 sinθ - 5 = 0 in the interval [0,360)is {θ∈ [0,360)∣θ = 230.48 ,309.521}

5. Mrs. Hoskins is going to plant her new
gorden. She purchases 4 tomato plants for
$2.59 each, a package of watermelon seeds
for $1.87, and adapeno plant for $3.88. How
much will Mrs. Hoskins spend on seeds and
plants for her new garden?
The solution is $ 16.11
The total amount of money spend by Mrs.Hopkins on seeds and plants is given by the equation A = $ 16.11
What is an Equation?
Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the equation be represented as A
Now , the value of A is
Let the cost of each tomato plant be = $ 2.59
The number of tomato plant = 4
The cost of 4 tomato plant = 4 x 2.59
The cost of 4 tomato plant = $ 10.36
Now ,
The cost of watermelon seeds = $ 1.87
The cost of adapeno plant = $ 3.88
So , the equation will be
The total amount of money A = cost of 4 tomato plant + cost of watermelon seeds + cost of adapeno plant
Substituting the values in the equation , we get
The total amount of money A = 10.36 + 1.87 + 3.88
The total amount of money A = $ 16.11
Therefore , the value of A is $ 16.11
Hence , the total amount of money is $ 16.11

A shop owner can buy two televisions and three DVD players for $1750 or four televisions and one DVD players for $1250. Find the cost of one of each
Answer:
Television = $200 and DVD player = $450
Step-by-step explanation:
→ Make 2 equations
Televisions = t and DVD players = d
2t + 3d = 1750
4t + d = 1250
→ Multiply the bottom equation by 3 to make the same variable of d
2t + 3d = 1750
12t + 3d = 3750
→ Minus the two equations to isolate the d variable
-10t = -2000
→ Divide both sides by -10 to find the cost of one television
t = 200
→ Substitute t = 200 back into 4t + d = 1250
800 + d = 1250
→ Minus 800 from both sides to isolate d
d = 450
