We first complete the square.
y=-x^2+2x+1
y=-x^2+2x-1+1+1
y=-(x-1)^2+2
The maximum point is (1,2) since -1 in ( ) meant 1 unit to the right and +2 meant 2 units up.
The maximum point is (1,2) but the maximum value means the y value which is simply just 2.
Done!

Answer:
10
Step-by-step explanation:
(4 * 5) / 2 = 20 / 2 = 10
Answer:
Triangle R and triangle S are congruent triangles, so finding the area of triangle S would give us the area of triangle R.
The area of a triangle can be calculated as 1/2(bh), where b is the base and h is the height.
In this case, we have: 1/2(5)(4). This simplifies to 10.
So, the area of triangle R is 10 square meters.

Eighty percent of a roof, or 2800 square feet of the roof, has been re-shingled.
What is the total area of the roof?
A 35,000 sq ft
B 22.400 sq ft
C 3500 sq ft
D 2240 sq ft
Answer:
a) 35,000 sq ft
Step-by-step explanation:
x = total area
the question is: 80% of what number equals 2800
.8x = 2800
x = 2800/0.8
x = 3500

The circle graph shows the percent of vegetables planted in a vegetable garden. There are 200 vegetable plants in all.
How many of the vegetable plants are green beans?
A. 12
B. 24
C. 76
D. 36
Number of green bean plants are 24. Therefore, option B is the correct answer.
What is circle graph?Circle graphs also known as pie charts are one of the most commonly used graphs to represent data using the attributes of circles, spheres, and angular data to represent real-world information. It is used to visualize information and data.
Given that, there are 200 vegetable plants in a vegetable garden.
From the circle graph, percentage of green beans is 12%.
So, number of green bean plants are
12% of 200
= 12/100 ×200
= 12×2
= 24
Therefore, option B is the correct answer.

0=1-2y+14x what is the slope and the y-intercept
Answer:
slope: 7
y-intercept: 1/2
Step-by-step explanation:
Put it into the form y = mx + b where m is the slope and b will be the y-intercept. (For example, in the equation y = 3x + 2 the slope is 3 and the y-intercept is 2).
[tex]0=1-2y+14x\\2y=1+14x\\2y = 14x+ 1\\y = 7x + 1/2[/tex]
So you know that m = 7, so the slope is 7
and
b = 1/2, so the y-intercept is 1/2.

Step-by-step explanation:
For the first few exponents multiply and the rest they add because like terms.
The trick is that when you raise a power to a power you multiply. Otherwise you add if the base value is the same.
Part I : Write the type of polynomial next to the terms (monomial, binomial, trinomial)
1. 6x-4
2. x2-2xy-7
3. 26b2
4. -8
Part II: Write the polynomial in standard form
5. 12+5y+6xy+8xy2
6. 34x+9x4+3x7-4x2
Part III: Adding polynomials
7. (p3+5p2+9p-6)+(5p3-8p+1)
8.(2p4+3p+9) +(4p4+3p3+p)
Answer:
Part I:
1. binomial
2. trinomial
3. monomial
4. monomial
Part ll :
5. 8xy2 + 6xy + 5y + 12
6. 9x4 + 3x7 - 4x2 + 34x
Part lll:
7. (p3+5p2+9p-6)+(5p3-8p+1)
= p3 + 5p2 + 9p - 6 + 5p3 - 8p + 1
= 6p3 + 5p2 + p - 5 ( add all the like terms i. e. those terms having the same power)
8. (2p4+3p+9) +(4p4+3p3+p)
= 2p4 + 3p + 9 + 4p4 + 3p3 + p
= 6p4 + 3p3 + 4p + 9 ( adding all the like terms i. e. those terms having same power )

solve 4x² - 3x - 2 = 0

Step-by-step explanation:

A rectangle has length (x + 5)cm and width (x –2)cm. Its area is 60 cm 2
Area = length x width
60 = (x+5) (x-2)
60 = x^2 + 3x -10
Subtract 60 from both sides:
x^2 +3x -70 = 0
Solve for x by finding 2 numbers when added together = 3 and when multiplied by each other = -70
x = -10 and 7
Since the sides have to be a positive number we need to use 7
The length = x+5 = 7+5 = 12 cm
The width = x-2 = 7-2 = 5 cm
