the common diiference of an ap is 4 . the last term is 72 and the sum of all terms is 600. find the first term and the number of terms
Answer:
a = - 24 ; n =25
a = 28 ; n = 25
Step-by-step explanation:
n = l - a/d + 1
d = common difference = 4
Last term = l = 72
n = 72 - a/4 + 1
4n = 72 - a + 4
4n = 76 - a
a = 76 - 4n - - - (1)
Sum of terms :
Sn = n/2(a + l)
Sn = 600
600 = n/2(a + 72)
1200 = n(76-4n +72)
1200 = 148n - 4n
4n² - 148n + 1200
Solving the quadratic equation :
Roots of n are :
12 and 25
From (1)
n = 12
a = 76 - 4(12) = 28
n = 25
a = 76 - 4(25) = - 24
Hence,
a = - 24 ; n =25
a = 28 ; n = 25

A number increased by 7 is 4 less than twice the number. Write the equation and solve
Answer:
The number must be bigger than 7 for the equation be true
If you put x= 7 or x= 6...it will not be true
Step-by-step explanation:
x+7< 2x
7< x
x> 7
Example x=9
9+7 < 2x9
16< 18 TRUE
The equation is x + 7 = 4 - 2x. Then the solution of the equation will be negative 1.
What is the solution to the equation?The allocation of weights to the important variables that produce the calculation's optimum is referred to as a direct consequence.
The definition of simplicity is making something simpler to achieve or grasp while also making it a little less difficult.
A number increased by 7 is 4 less than twice the number.
Let the number be 'x'. Then the inequality is given as,
x + 7 = 4 - 2x
Simplify the equation, then we have
x + 7 = 4 - 2x
x + 2x = 4 - 7
3x = - 3
x = -3/3
x = -1
The equation is x + 7 = 4 - 2x. Then the solution of the equation will be negative 1.

Cameron created a composite figure by stacking three cubes the cubes measure 2 inches on each side  what is the volume of the composite figure
Answer:
24 cubic inches.
Step-by-step explanation:
The volume of one cube = s * s * s or s^3
s = 2 inches
V = s^3
V = 2 * 2 * 2 or 2^3
V = 8 cubic inches.
The volume of 3 of them is 8*3 = 24 cubic inches.

Describe all 6 parts, for example, side "a" is one of the legs of the right triangle and is opposite Angle A, which is an acute angle, and side a appears to be the shortest side.
Answer:
The description of the 6 parts of the right triangle ABC are as follows;
The legs of the right triangle are side "a" and side "b"
The hypotenuse side of the right triangle is side "c"
The acute angles are ∠A and ∠B
The 90° angle is ∠C
The description of the 6 parts are therefore given as follows;
1) A; ∠A is the acute angle opposite side "a" and ∠A is formed between the hypotenuse side "c" and the leg "b"
2) B; ∠B is the acute angle opposite side "b" and ∠B is formed between the hypotenuse side "c" and the leg "a"
3) C; ∠C is the 90° angle (right angle) opposite the hypotenuse side "c" and ∠C is formed between the the two legs "a" and "b"
4) a; Side "a" is one of the two legs of the right triangle ΔABC and it is the leg opposite to ∠A
5) b; Side "b" is one of the two legs of the right triangle ΔABC and it is the leg opposite to ∠B
6) c; Side "c" is the hypotenuse side of the right triangle ΔABC and it (the hypotenuse side) is (all the time) the longest side of the right triangle and it is the leg opposite to ∠A

Candice drives a total of 48 miles each day to work and get back home. She works five days a week. Her car gets 21 miles per gallon of gas. About how many gallons of gas does she need to drive to work and back home each week
Answer:
Total gallon of fuel used = [tex]11.428[/tex] gallons
Step-by-step explanation:
Given -
The total distance travelled by car in one gallon of gas = 21 miles
Total distance travelled each day = 48 miles
Number of days days in a week in which Candice drive is 5 days
Total miles travelled per week = [tex]48*5[/tex] = 240 miles
Total gallon of fuel used = [tex]\frac{240}{21} = 11.428[/tex] gallons

Answer:
Hello Love! In this problem it gives you the diameter but when doing area we need the radius and remember radius is always half of the diameter so we are going to get 12 as are radius and square it so 12 × 12 = 144 now we just multiply by pi so 144 × 3.14 = 452.16 but sense we are rounding it it will be 452.4 so our answer is C

find constants p and q such that x^4-2x^3-x^2+2x+10=(x^2+px+5)(x^2+qx+2)
Answer:
p = -4 q = 2
Step-by-step explanation:
Expand the brackets ( yes the entire thing).group together the values with same co-effiecients; like (q+p)x^3 etc etc.equate the co-effiecients on the left hand side to the now grouped ones on the right, for example [x^3]: -2x^3= (q+p)x^3, the x^3 cancels and ull get an equation only in terms of p and q. do the same for [x] and ull get an equation with only q, solve this and get the value for q [q = 2].sub in this value for the [x^3] equation and ull get an answer for p [p= -4].hope my explanation is understandable lol

In the terminal side of an angle in standard position lies on -4y=3x and x>0, find the exact values of the trigonometric functions of 0
Answer:
sec ∅ = 5/4
cosec ∅ = -5/3
cot ∅ = -4/3
Tan ∅ = - 3/4
sin ∅ = -3/5
cos ∅ =4/5
Step-by-step explanation:
Given : -4y = 3x , x > 0
i.e. 3x + 4y = 0 , x >0
4y = -3x ∴ y = - 3/4 x
The values of trigonometric functions of ∅ are
Tan ∅ = opposite / adjacent
= - 3/4 ( given that y = slope which is = Tan ∅ )
now we will find the hypothenuse ( c )
c^2 = a^2 + b^2 = 9 + 16 = 25
therefore ; c = √25 = 5
hence the trig functions are :
sin ∅ = -3/5
cos ∅ =4/5
sec ∅ = 5/4
cosec ∅ = -5/3
cot ∅ = -4/3
