Step-by-step explanation:
What is the range of the graph?
Answer:
[tex]-5 \leq y \leq 5[/tex]
Step-by-step explanation:
Just find the minimum point and the maximum point of the graph in the y-axis.
The minimum value is -5 and the maximum value is 5,
so the y- value of the graph can be any point between -5 and 5 (including -5 and 5).
And the range of the graph is greater or equal to -5 and lesser or equal to 5.

Tait earns $89,000 this year. He gets a cost of living raise to compensate for yearly inflation of 396. What will his raise be next year?
Step-by-step explanation:
His raise is 3% of 89.000
.03*89.000=$2.670
His new salary is ( to get the number you need to add 89.000+2.670={$91.67})
Tait's raise in the coming year will be $2,670
Question meant to say that the inflation is 3%.
Inflation refers to the general rise in the price of goods and services in a country. It therefore makes a currency weaker because that currency will only be able to buy less than it could before.
The raise will have to be 3% as well to ensure that inflation does not affect Tait
The raise is based on his salary so can be found by:
= Amount Tait earns x Inflation rate
= 89,000 x 3%
= $2,670
In conclusion, the raise is $2,670

5. A cylindrical pillar is 50 cm in diameter and 3.5 m in height. Find the cost of painting
the curved surface of the pillar at the rate of 12.50 per m.
Answer:
The cost of painting the curved surface of pillar is: 68.69
Step-by-step explanation:
Given that
Diameter of pillar = d = 50 cm
As the height is in meters and we have to find the cost in per square meter, we have to convert cm into meters.
So,
d = 50/100 = 0.50 m
Now the radius will be:
[tex]r = \frac{d}{2} = \frac{0.50}{2} = 0.25m[/tex]
Also
Height = 3.5m
The curved surface area of cylinder is given by:
[tex]CSA = 2\pi rh[/tex]
Putting the values
[tex]CSA = 2 * 3.14 * 0.25 * 3.5 = 5.495\ m^2[/tex]
It is given that the cost per square meter is 12.50
The total cost for 5.495 m^2 will be: 12.50 * 5.495 = 68.6875
Rounding off to nearest hundredth: 68.69
Hence,
The cost of painting the curved surface of pillar is: 68.69

Step-by-step explanation:
4x + 8 = 4
subtract 8 from each side
4x = -4
divide each side by -4
x= -1
Answer:
x = -1
Step-by-step explanation:
You would first multiply 4 with is the first number by x and 2. You would get 4x+8. The you would subtract 8 by both sides. 4x = -4. The you would divide 4 by -4. Which will get you -1.

Which property of equality should be used with the equation c+5=78 to solve?
Answer:
the subtraction property of equality
Step-by-step explanation:
We use the "subtraction property of equality" to solve for the unknown in the equation:
c + 5 = 78
subtract 5 from both sides:
c + 5 - 5 = 78 - 5
c = 73

X is carrying out a series of experiments which involve using increasing amounts of a chemical. In the first experiment he uses 6g of the chemical and in the second experiment he uses 7.8g of the chemical.
(i) Given that the amounts of the chemical used form an arithmetic progression, find the total amount of chemical used in the first 30 experiments. [4]
(ii) Instead it is given that the amounts of the chemical used form a geometric progression. X has a total of 1800g of the chemical available. Show that N, the greatest number of experiments possible, satisfies the inequality
1.3N ≤ 91.
and use logarithms to calculate the value of N.
Answer:
a) 963g
b) 17
Step-by-step explanation:
i) Now we must first find the common difference of the AP
d = 7.8 -6 = 1.8
Now the sum of the AP gives the total amount of chemical used for 30 experiments
Sn = n/2 [2a + (n-1)d]
n= 30, a = 6, d= 1.8
Sn = 30/2[2(6) + (30-1) (1.8)]
Sn = 15[12 + 52.2]
Sn = 963g
ii)For the G.P the common ration is (r)= 7.8/6 = 1.3
Since r>1, sum of GP = a (r^n -1)/r-1
If sum = 1800g
1800= 6(1.3^n -1)/1.3 - 1
1800 = 6(1.3^n -1)/0.3
1800 * 0.3 = 6(1.3^n -1)
540 = 6(1.3^n -1)
540/6 = (1.3^n -1)
90 = 1.3^n -1
90 + 1 = 1.3^n
1.3^n = 91
log 1.3^n = log 91
nlog1.3 = log 91
n = log91/log 1.3
n = 1.959/0.114
n = 17

What is the sum of the interior angles of a polygon?
The sum of the interior angles of a polygon is given by the formula
Sum of Interior angles of a polygon with n sides is
nθ = 180 ( n - 2 )
where n is the number of sides
θ = angle in degrees
Given data ,
Let the interior angle sum of the polygon be = A
Now , the value of A is calculated by
The number of sides of the polygon n = 31
So , the interior angle sum of the 31-gon is given by the equation
Sum of Interior angles of a polygon with n sides is
nθ = 180 ( n - 2 )
where n is the number of sides , so
Substituting the values in the equation , we get
The value of nθ = 180 ( n - 2 )
The value of nθ = 180 ( 31 - 2 )
The value of nθ = 180 x 29
The value of nθ = 5220°
Therefore , the value of A is 5220°
Hence , The interior angle sum of 31-gon is A = 5220°

A group of students go out to lunch. If four have burritos and two have tacos, the bill will be $19.00. If three have burritos and three have tacos the bill will be 17.25. Find the price of each burrito and taco
Answer:
burritos cost $4
tacos cost $ 1.75
Step-by-step explanation:
let b represent the price of burritos
let t represent the price of tacos
3b + 4t = 19
5b + 3t = 25.25
multiply the first equation by -3 and second by 4 to eliminate t
-3(3b + 4t = 19)
4(5b + 3t = 25.25)
-9b - 12t = -57
20b + 12t = 101
add both equations
11b = 44
11 11
b = 4
substitute b = 4 into any equation to find the price of tacos
