Answer:
an = a1 + d(n - 1)
a88 = 4 + (-5)(88 - 1)
a88 = 4 + (-5)(87)
a88 = 4 - 435
a88 = -431
So, the 88th term of the arithmetic sequence is -431.
a recipe uses 10 cups of flour. you can only measure using 2/3 cups.
How many 2/3 cups are needed for the recipe?
Ok so I am not exactly sure if you want to know how many whole cups can be added or simply how many 2/3 cups make up 10, but heres what I found.
So to find how many 2/3 is in 10 cups you simply have to divide
10/(2/3) = 15
So 10 cups of flour is 15 (2/3) cups of flour.
Hope this helps :)
Pi approx A cylinder has a height of 20 yards and a diameter of 18 yards . What is its volume ? Use 3.14 and round your answer to the nearest hundredth .
Answer:
5086.8 cubic yards
Step-by-step explanation:
Given data
Height = 20yards
Diamter= 18 yards
Radius= 9 yards
The expression for the volume of a cylinder is given as
V=πr^2h
substitute
V=3.14*9^2*20
V=3.14*81*20
V=5086.8 cubic yards

Find the volume
A. 150 cm3
B. 180 cm3
C. 90 cm3
D. 90 cm2
Answer:
268 in²
Step-by-step explanation:
The surface area is basically the entire area of the figure. You can do it multiple ways, but this is how I did it. I found the area of each side and added them all together. There are three sets of identical sides. First, we'll calculate the area of the side with lengths 10" and 8".
10 · 8 = 80
There are two of these sides, so currently we have 80 + 80.
Next, the area of the sides with lengths 8" and 3". These are the sides at the top and bottom.
8 · 3 = 24
So to our equation we now have 80 + 80 + 24 +24.
For the final two sides, we have the dimensions 10" and 3".
10 · 3 = 30
To our equation, we add this to get 80 + 80 + 24 + 24 + 30 +30.
Add all these numbers together for 268.
In the correct form, we add the square symbol to show that we are talking about area. The answer is 268 in². Good luck :D
Calculate the discriminant f(x)=x2-4x+7
Answer:
Option 1,3,4,6 are correct
Explanation
Step-by-step explanation:
we have formula for discriminant that is D=b^{2} -4acD=b
2
−4ac
when D>0 the roots are real and unequal
when D= 0 roots are real and equal
and when D< 0 roots are imaginary or not real and unequal
In 1st equation: x^2+6x+8x
2
+6x+8
a=1,b=6,c=8 on substituting the values in the formula we will get
D=6^2-4(1)(8)=4 > 0D=6
2
−4(1)(8)=4>0 hence real and unequal roots.
In 2nd equation:x^2+4x+8x
2
+4x+8
a=1,b=4,c=8 on substituting values in formula
D=4^2-4(1)(8)=-16 < 0D=4
2
−4(1)(8)=−16<0 so roots are not real
In 3rd equation x^2-12x+3x
2
−12x+3
a=1,b=-12,c=3 on substituting values
D=D=(-12)^2-4(1)(3)=132 > 0D=(−12)
2
−4(1)(3)=132>0 roots are real and unequal
In 4th equation: x^2+4x-1x
2
+4x−1
a=1,b=4,c=-1 on substituting the values
D= 4^2-4(1)(-1)=20 > 0D=4
2
−4(1)(−1)=20>0 real roots
In 5th equation:5x^2+5x+45x
2
+5x+4
a=5,b=5,c=4 on substituting the values
D=5^2-4(5)(4)=-55 < 0D=5
2
−4(5)(4)=−55<0 roots are not real
In 6th Equation: x^2-2x-15x
2
−2x−15
a=1,b=-2,c=-15 on substituting the values
D=(-2)^2-4(1)(-15)=64 > 0D=(−2)
2
−4(1)(−15)=64>0 roots are real

Select one or more expressions that together represent all solutions to the equation your answer should be in radians sin(x) = -.25
Answer:
-0.25268 rad + 2πn , 3.394273 rad + 2πn
≈ - π /12 + 2πn, π + 2πn
Step-by-step explanation:
sin( x ) = -0.25
x = sin^-1 ( -25 )
The solutions of the equation sin( x ) = -0.25 are :
X = -0.25268rad + 2πn , 3.394273rad + 2πn
≈ - π /12 + 2πn, π + 2πn

Isabel has ridden 16 miles of a bike course. The course is 80 miles long. What percentage of the course has Isabel ridden so far?
Answer:
20%
Step-by-step explanation:
Divide 16 by 80 and you get 0.2 as an answer and to get a percent you move the decimal 2 places to the right to fet 20%
Isabel has completed 20 percent of the race of 80 miles.
What is the percentage?A percentage is a quantity or ratio that, in mathematics, represents a portion of one hundred. It is one method for illustrating a relationship between two integers that has no dimensions.
Given, Isabel has ridden 16 miles of a bike course. The course is 80 miles long. From the general formula of percentage:
For the percentage, we have to divide the value by the total value and then multiply the result by 100.
percentage of the course has Isabel ridden so far = (16/80) * 100
percentage of the course has Isabel ridden so far = 1/5*100
percentage of the course has Isabel ridden so far = 20%
Therefore, Isabel has ridden 20 percent of the course which is 80 miles.
