1.Consider the quadratic relation y = x^2 – 6x – 16.
a) Factor this equation using the Trinomial Method (find two numbers that multiply to 'c' and add to 'b'; the factored form has 2 pairs of brackets).
b) Find the x-intercepts (zeroes) of the relation. Remember to let y = 0 then solve for each x separately.
2. Consider the quadratic relation y = 2x^2 + 6x – 80. a) Factor this equation by:
1. Determining the greatest common factor (GCF).
2. Factoring the equation using common factoring.
3. Factor the expression inside the brackets using the Trinomial Method (find two numbers that multiply to 'c' and add to 'b'; the factored form has 2 pairs of brackets).
b) Find the x-intercepts (zeroes) of the relation. Remember to let y = 0 then solve for each x separately.
Answer:
Step-by-step explanation:
1.Consider the quadratic relation y = x^2 – 6x – 16.
a) Factor this equation using the Trinomial Method (find two numbers that multiply to 'c' and add to 'b'; the factored form has 2 pairs of brackets).
[y = x^2 – 6x – 16 : Two numbers when multiplied = -16, but when added = -6, would be: -8 and 2. [-8+2 = -6, and -8*2 = -16] This would lead to (x+2)(x-8) as the two factors.
b) Find the x-intercepts (zeroes) of the relation. Remember to let y = 0 then solve for each x separately.
(x+2)=0; x= -2
(x-8)=0; x = 8
2. Consider the quadratic relation y = 2x^2 + 6x – 80.
a) Factor this equation by:
1. Determining the greatest common factor (GCF).
The GCF is 2: 2*(x^2 + 3x - 40)
2. Factoring the equation using common factoring.
2*(x^2 + 3x - 40): Two numbers that when multiplied = -40, but added = 3, would be 8 and -5. So we can factor:
2*(x + 8)(x - 5)
3. Factor the expression inside the brackets using the Trinomial Method (find two numbers that multiply to 'c' and add to 'b'; the factored form has 2 pairs of brackets).
2*(x + 8)(x - 5)
b) Find the x-intercepts (zeroes) of the relation. Remember to let y = 0 then solve for each x separately.
0 = (x + 8) and 0=(x - 5); x = -8, and x=5

Andrew is hiking in a mountainous area of a state park. Use the given key features to sketch a graph.
y-intercept: Andrew starts at an elevation of 0 feet.
Extrema: Andrew's maximum elevation is 800 feet.
Increasing: At the start of the hike, Andrew's elevation increases steadily for 30 minutes. Then he stops to rest for 5 minutes.
Decreasing: Andrew hikes back to his starting point for the final 20 minutes.
Using the features, a piece-wise function is defined, and the graph is sketched at the end of this answer.
A piece-wise function is a function that has multiple definitions, depending on the value of the input.
He starts at 0 feet, and reaches a maximum elevation of 800 feet in 30 minutes, with a steady(linear) increase thus, for the first 30 minutes, the definition is:
[tex]h(t) = \frac{800}{30}t, 0 \leq t < 30[/tex]
For the next 5 minutes, he stops to rest, at the maximum elevation of 800 feet, thus, the definition is:
[tex]h(t) = 800, 30 \leq t < 35[/tex]
For the final 20 minutes, he descends 800 meters, at a linear rate, thus:
[tex]h(t) = 800 -\frac{800(t-35)}{20} = 800 - 40(t - 35), 35 \leq t \leq 55[/tex]
Using these definitions, the graph is sketched at the end of this answer.

Answer:
Step-by-step explanation:
6) Area of rectangle = 78.5 sq . cm
length * width = 78.5
15.7 * width = 78.5
Width = 78.5/15.7
= 5 cm
7) circumference of circle = 44 cm
[tex]2\pi r = 44 \\\\2*\dfrac{22}{7}*r=44\\\\r = 44*\dfrac{7}{2*22}\\\\r = 7[/tex]
r = 7 cm

A cube has a volume of 73 cubic centimeters. What is its surface area in
square centimeters?
Just type the number of the answer.
Answer:
104.80 cm²
Step-by-step explanation:
Formula to know: Volume = e³ ; SA = 6e²
V = e³ Substitute what you know V = e³ and solve
73 = e³
[tex]\sqrt[3]{73}[/tex] = e one edge of the cube
Find the SA
SA = 6e² Substitute the value for e
SA = 6([tex]\sqrt[3]{73}[/tex])²
SA = 6([tex]\sqrt[3]{73} \sqrt[3]{73}[/tex] )
Sa = 104.80

Answer using steps: An ice cream shop sells ice cream cones with exactly 1 of 3 ice cream flavors in the cone. The 3 flavors are vanilla, chocolate, and strawberry. last saturday, the shop sold 42 cones. it sold 11 more with chocolate than with vanilla and 2 more with vanilla than with strawberry. how many cones with strawberry ice cream did the shop sell that saturday
Step-by-step explanation:
udhfhxhsjdjejdbcjdxbshajdddjwjed
The number of strawberry ice cream cones the shop sells that Saturday is 9 ice cream.
What is a linear equation?
A linear equation has one or two variables. No variable in a linear equation is raised to a power greater than 1.No variable is used as the denominator of a fraction. A linear equation is defined as an equation that is written in the form of ax+by=c.
calculation:-
An ice cream shop sells ice cream cones with exactly 1 of 3 ice cream flavors in the cone.
let a number of strawberry ice cream this shop sold on satrday=X
number of vanilla ice cream shops sold = X+2
number of Chocolate ice cream shops sold = X+2+11
Total number of icecream sold on Saturday =42
⇒ X+ X+2+ X+2+11 = 42
⇒ 3X + 15 =42
⇒ 3X = 27
⇒X = 27/3
⇒ X = 9

Answer:

Step-by-step explanation:
Slope=Rise/Run
What does that mean? It means that the slope is equal to the change in y over the change in x.
It can be defined as m=(y1-y2)/(x1-x2)
Let's pick two random coordinates.
Say...
(30,10) and (40,30).
x1=30
x2=40
y1=10
y2=30
So when we plug those in, we get
m= (10-30)/(30-40)
which simplifies to (-20)/(-10)
which simplifies to 2.

Answer:
D
Step-by-step explanation:
∠1 + ∠2 = 180 {Supplementary angles}
6x + 15 + 3x + 3 = 180
6x + 3x + 15 + 3 = 180
Combine like terms
9x + 18 = 180
Subtract 18 from both sides
9x = 180 - 18
9x = 162
x = 162/9
x = 18
∠2 = 3x +3
= 3*18 + 3
= 54 + 3
∠2 = 57°

Answer is option D) 57°

Factorise; 2 cubed multilpied by 2 squared.
[tex] \large \boxed{\mathfrak{Answer \: with \: Explanation} \downarrow}[/tex]
Firstly let's change the statement to a numerical expression.
[tex] \cdot\sf \: 2 \: cubed = 2 ^{3} \\ \cdot\sf \: multiplied \: by = \times \\\cdot\sf \: 2 \: squared = 2 ^{2} \\ \\ \sf \: So, \: the \: expression \: becomes \rightarrow \boxed{\tt {2}^{3} \times {2}^{2} }[/tex]
__________________
[tex]2 ^{3} \times 2^{2} [/tex]
To solve this, we must know that while multiplying exponents which have a same base we must take their base as common & add the exponents.
[tex]2 ^{3} \times {2}^{2} \\ = (2) ^{3 + 2} \\ = \underline{\underline{ 2 ^{5} }}[/tex]
We got 2⁵. Now, multiply 2 five times to get the answer.
[tex] {2}^{5} \\ = 2 \times 2 \times 2 \times 2 \times 2 \\ = \huge \boxed{\boxed{\bf 32}}[/tex]

At the end of a snowstorm, Grace had 15 inches of snow on her lawn. The
temperature then increased and the snow began to melt at a constant rate of 2.5
inches
per hour. Assuming no more snow was falling, how much snow would Grace
have on her lawn 2 hours after the snow began to melt? How much snow would Grace
have on her lawn after t hours of snow melting?
Part 1
The snow melts at 2.5 inches per hour. After 2 hours, 2*2.5 = 5 inches has melted overall. We started with 15 inches, so there are 15-5 = 10 inches of snow left after 2 hours.
Answer: 10 inches of snow==================================================
Part 2
Let t be the number of hours that have elapsed. Because the snow melts at a rate of 2.5 inches per hour, this means after t hours, 2.5t inches of snow melts away. Subtract this from the 15 inches we start with to get 15-2.5t. This expression is the same as -2.5t+15
Answer: Either 15-2.5t or -2.5t+152. Given that a = 3 , b = 2, and c = −1, evaluate each of the following expressionsa) (a+3b)
Answer:
9
