Step-by-step explanation:
h=b+2(assume h is hieght and b is base)
b*(b+2)=60
bb+2b=60
b=-1+√61
h=1+√61
Answer:
base=10
height=12
Step-by-step explanation:
Area of triangle formula is given by: A = (1/2)*b*h
where b: base of the triangle
h: height of the triangle
Given that: h=b+2
A= 60 square yards
Solution:
60= (1/2)*b*(b+2)
[tex]\frac{b(b+2)}{2}[/tex] = 60
b²+2b=120
b²+2b-120=0
We got the quadratic equation: b²+2b-120=0
solve it to find b:
Let x: coefficient of b² (x=1)
Let y: coefficient of b (y=2)
Let z: constant (z= -120)
discriminant= y² - 4xz = 4 - 4(1)(-120) = 484
discriminant>0 so the equation has two roots:
b1= (-y-redical discriminant)/2x = (-2-redical(484))/2 = -12
b2= (-y+redical discriminant)/2x = (-2+redical(484))/2 = 10
b1= -12 is rejected because the base can't be negative
So b2=base=10
Now that we found the base, substitute to get the height:
h= b+2 = 10+2 =12
So height=12

Answer: (x - 1)(x - 23)
Step-by-step explanation:
First, we can factor the x² part:
(x)(x)
Next, we will look at the -24x and +23
-> We need two numbers that multiply to 23 and add to -24
-> 23 is a prime number, so we will use 1 and 23
For -24, 1 and 23 must be added together. Since a negative times a negative is a positive, and a negative plus a negative is a positive, we will turn them into -1 and -23.
This gives us a final answer of:
(x - 1)(x - 23)
Answer: (x - 1)(x - 23)

Ayden is 1.85 meters tall. At 2 p.m., he measures the length of a tree's shadow to be 39.55 meters. He stands 35.4 meters away from the tree, so that the tip of his shadow meets the tip of the tree's shadow. Find the height of the tree to the nearest hundredth of a meter.
The height of the tree is 4.15m
We are given that
Height of Joshua, h=1.85 m
Length of tree's shadow, L=39.55 m
Distance between the tree and Joshua=35.4 m
We have to find the height of the tree.
BC=35.4 m
BD=39.55m
What is the height?CD=BD-BC
CD=-35.4 m=4.15 m
EC=1.45 m
All right triangles are similar. When two triangles are similar then the ratio of their corresponding sides is equal.
[tex]\triangle ABD=\triangle ECD[/tex]
[tex]\frac{AB}{EC}=\frac{BD}{CD}[/tex]
Substitute the values
[tex]\frac{AB}{1.45}=\frac{39.55\times 1.45}{4.15} \\\\AB=20.39[/tex]
Hence, the height of the tree=20.39 m

Circumference of a circle
We are told that the string is wound symmetrically around a circular rod.
Now, the circumference of the rod is 4 cm and length is 12 cm.
Now, circumference is also the length of a circle. Thus, one wound of the string will be equal to the circumference of the rod.
Thus, one wound = 4 cm
Since the string makes 4 turns about the rod, then;
Length of string = 4 × 4 = 16 cm

Factor the expression using the greatest common factor 16x + 12y
Answer:
4(4x + 3y)
Step-by-step explanation:
Given expression: 16x + 12y
Factors of 16: 1, 2, 4, 8, 16
Factors of 12: 1, 2, 3, 4, 6, 12
Therefore, the greatest common factor of 16 and 12 is 4.
As the expression has two variables, the variables cannot be factored.
Therefore, factored expression: 4(4x + 3y)
16x+12y
Factor each
16x=4×4x12y=4×3yTake 4 common as GCF

Answer:
Lower quartile = 6
Median = 8
Upper quartile = 9
Step-by-step explanation:
If you take away a number from each end of the number set one by one, you will end up with 7 and 9 in the middle. To find the median between two numbers, add them together then divide them by 2.
7 + 9 = 16
16 ÷ 2 = 8
_________________
To find the lower and upper quartiles, split the number set into two where the median is, then, find the median of those two sections.
Lower quartile: 4, 5, 6, 6, 7
Median = 6
-
Upper quartile: 9, 9, 9, 9, 9
Median = 9
So, the median of the whole set is 8, the lower quartile is 6, and the upper quartile is 9.

Answer:
297.375 miles

Since lisa rides 15.25 miles in 1 week and we are looking for how many miles she rides in 19.5 weeks, we must multiple 15.25 miles by 19.5 because she rides 15.25 miles, 19.5 times.

The directions on a box of Luigi’s Pizza Mix are as follows: Spread the dough to the edges of a circular pan or a 10-inch by 14-inches rectangular pan. You will need to use the following formulas to answer the questions below. For a circle: A = πr2 where π = 3.14C = 2πr For a rectangle: A = lw P = 2l + 2w a. If you used the same amount of dough, how large a circular pan would you need to make a pizza of the same area and thickness as one made in the rectangular pan? *
The circular pan must have a radius of 6.68 inches.
How large a circular pan would you need?
The area of the circular pan just be the same as the area of the rectangular pan.
The rectangular pan is 10in by 14 in, so its area is:
A = 10in*14in = 140in^2
Then the circular pan must have an area:
A' = 3.14*r^2 = 140in^2
We can solve this for r:
r = √(140in^2/3.14) = 6.68 in
The circular pan must have a radius of 6.68 inches.

Expand: f(z) = z / (z-1) (2-z) as Laurent series for |z| < 1
Most problems like this can be done with two tools only: partial fractions, and the result 1/(1−w)=1+w+w2+⋯ for |w|<1. So first split your function f into 1/(z−2)−1/(z−1). I will show you how to cope with one of these factors, 1/(z−2). Writing this as −1211−z/2 is tempting but no good: the "1/(1−w)" expansion will converge only for |z/2|<1, not on the regions you are supposed to care about. So you take out a factor of z−1 instead:
1/(z−2)=z−111−2/z
The final term can be expanded with the 1/(1−w) series, valid for |2/z|<1 that is |z|>2. So that does give you a Laurent series valid in the right region (once you multiply bu z−1. These methods can be used to solve all of your problems.
Partial fractions:
[tex]f(z) = \dfrac z{(z-1)(2-z)} = -\dfrac1{1-z} + \dfrac2{2-z}[/tex]
For |z| < 1, we have
[tex]\displaystyle \frac1{1-z} = \sum_{n=0}^\infty z^n[/tex]
and
[tex]\displaystyle \frac2{2-z} = \frac1{1-\frac z2} = \sum_{n=0}^\infty \left(\frac z2\right)^n[/tex]
(The latter series is valid for |z/2| < 1 or |z| < 2, but |z| < 1 is a subset of this region.)
Then
[tex]\boxed{f(z) = \displaystyle \sum_{n=0}^\infty \left(\frac1{2^n} - 1\right) z^n}[/tex]
