Answer:
f(3) = -41
Step-by-step explanation:
f(x) = x³-9x²+5x-2
now,
f(3) = 3³-9×(3)²+5×3-2
= 27-9×9+5×3-2
= 27-81+15-2
= -41

Answer:
Relation 1: Not a function
Relation 2: Not a function
Relation 3: Function
Relation 4: Not a function
Step-by-step explanation:
Recall: a relation can only be a function if and only if each domain value has only 1 range value mapped to it or related to it. This means that a domain value can only have exactly one range value for the relation to be qualified a function.
✔️Relation 1 is NOT A FUNCTION.
Rationale: Two of the domain values (star and sky) is having more than 1 range value assigned to each.
✔️Relation 2 is NOT A FUNCTION:
Rationale: domain value, 9, has several range values assigned to it.
✔️Relation 3 is A FUNCTION:
Rationale: each domain value do not have more than one range values assigned to it.
✔️Relation 4 IS NOT A FUNCTION:
Rationale: the domain value, 6, has two range values, m and d, assigned to it.
if a graph shows no solution what is the inequality
If the number on the other side of the inequality sign is negative, your equation either has no solution or all real numbers as solutions. Use the sign of each side of your inequality to decide which of these cases holds. If the number on the other side of the inequality sign is positive, proceed to step 3.

What is the slope of the following graph?
Suppose that the store manager of a small rural pharmacy is doing a linear regression of daily sales of over-the-counter (OTC) decongestant nasal sprays on forecasted pigweed pollen count. He would like to determine if he can use a straight ine equation to predict OTC decongestant nasal spray sales from the allergy forecast for pigweed pollen. The store manager records the data for five random days. The pollen forecast is for pigweed only and is given in parts per square meter (ppm )2
Pollen forecast OTC decongestant sales (dollars)
14 $101
19 $89
13 $48
6 $21
9 $47
The store manager calculates the regression equation for the data as 5.514x-6.073.
Determine the standard error of the slope of the regression line, SEb, for the data. Give your answer precise to at least three decimal places SE=______.
Answer:
3.83
Step-by-step explanation:
Mean of x = Σx / n
Mean of x = (14 + 19 + 13 + 6 + 9) / 5 = 12.2
Sum of square (SS) :
(14-12.2)^2 + (19-12.2)^2 + (13-12.2)^2 + (6-12.2)^2 + (9-12.2)^2 = 98.8
Mean of y = Σy / n
Mean of y = (101 + 89 + 48 + 21 + 47) / 5 = 61.2
Σ(y - ybar)² = (101-61.2)^2 + (89-61.2)^2 + (48-61.2)^2 + (21-61.2)^2 + (47-61.2)^2 = 4348.8
df = n - 2 = 5 - 2 = 3
Σ(y - ybar)² / df = 4348.8 / 3 = 1449.6
√(Σ(y - ybar)² / df) = √1449.6 = 38.074
Standard Error = √(Σ(y - ybar)² / df) / √SS
Standard Error = 38.074 / √98.8
Standard Error = 3.83

What is the value of 0.5–0.05? Write your answer as a fraction in lowest terms.
Answer:
Heyaaa!!! I'm Pinky!! And i'm here to inform you that you're answer is...
Step-by-step explanation:
!!!
0.5–0.05= 0.45
0.45 In fraction form is Simply:
9/20 (And that's on lowest terms!)
If you would want it in percentage form to that would simply be:
45%
Have A Nice Day!!!!
~Pinky~
The value of 0.5–0.05 is a fraction in the lowest terms = 9/20.
Use the concept of fraction defined as:
A fraction is a part of the whole number and a way to split up a number into equal parts. Or, A number which is expressed as a quotient is called a fraction. It can be written as the form of p: q, which is equivalent to p / q.
The given expression is: 0.5–0.05
Subtract 0.05 from 0.05
0 . 5 0
-0. 0 5
0 . 4 5
So, 0.5–0.05 = 0.45
Multiply and divide by 100 we get,
[tex]0.45\times \dfrac{100}{100} = \dfrac{45}{100}[/tex]
Divide both the numerator and denominator by 5 we get,
[tex]\dfrac{45}{100} = \dfrac{9}{20}[/tex]
Hence,
0.5–0.05 in the lowest fraction is 9/20.

= (216 / 4) - 20 + 3 * 5
= (216 / 4) - 20 + 15

Principal, $3000; Annual interest rate, 5.4%; time, 5 years
Answer:
SI = $810
Amount = $3,810
Step-by-step explanation:
Given that ,
P = $ 3,000 R = 5.4% T = 5 yrs .We can use the formula of SI to find the interest as ,
=> SI = P × R × T / 100
=> SI = $ 3000 × 5.4 × 5 / 100
=> SI = $ 30 × 5.4 × 5
=> SI = $ 810 .
If you want to know total amount , then ,=> Amount = SI + P
=> Amount = $ 810 + $ 3,000
=> Amount = $ 3,810
Hence the Amount is $3,810 and the SI is $810 .Answer:
Step-by-step explanation:
3000*(.054)(5)= $810

A sphere shaped orange has a diameter of 7 centimeters. Find the volume of the orange to the nearest tenth.
22cm^3
Step-by-step explanation:
My education system is different so I dont know what nearest tenth would mean in this .
But going mathematically:
Its diameter is 7 centimetres.
So to find its volume we can use the formula pi/d or pi/r^2
Now, 22/7÷7 would be 22cm³.

(05.02)A farmer has decided to divide his land area in half in order to plant soy and corn Calculate the area of the entire area so he knows how much soil is needed. SOY #6 yards 6 yards CORN 2.5 yards 6.5 yards Each bag of soil covers 15 Square yards. How many bags should the farmer purchase? 0 1 bag O2 bags O 3 bags 4 bags
9514 1404 393
Answer:
4 bags -- the correct answer is marked
Step-by-step explanation:
The area of a parallelogram is given by the formula ...
A = bh
where b is the base length and h is the height.
Here, the base is the sum of lengths 2.5 yd and 6.5 yd. The height is given as 6 yd. So, the area is ...
A = (2.5 yd + 6.5 yd)(6 yd) = 54 yd²
At 15 yd² per bag, the farmer will need ...
(54 yd²)/(15 yd²/bag) = 3 3/5 bags
Assuming the farmer can purchase only whole bags, the farmer should purchase 4 bags of soil.
