Answer:
The vertex of the graph is:
the minimum point for a parabola that opens upwardsthe maximum point for a parabola that opens downwardsAs this parabola opens upwards, the vertex is the minimum point.
From inspection of the graph, vertex = (-3, -1)
Equation of the graph
From inspection we can see that the x-intercepts are when
x = -4 and x = -2
[tex]\sf x = -4 \implies x+4=0[/tex]
[tex]\sf x = -2 \implies x+2=0[/tex]
Therefore:
[tex]\sf y=(x+4)(x+2)[/tex]
Expand:
[tex]\sf \implies y=x^2+6x+8[/tex]
Answer:
[tex]B)f(x) = {x}^{2} + 6x + 8[/tex]
Step-by-step explanation:
Let [tex] f(x)=x^2[/tex] be the parent function. With transformation of function, firstly,we know that,
We can move it up or down by adding a constant to the y-valuealgebraically
g(x)=x²+CClearly, The parabola is moved down by 1 unit thus, C is -1. Therefore our function transforms to
f(x)=x²-1secondly, we know that,
We can move it left or right by adding a constant to the x-valuealgebraically,
g(x)=(x+C)²in case,
C is positive, g(x) moves to the left and vise versaSince the parabola is moved left by 3 unit, C is +3, and hence Our function eventually becomes
[tex]f(x) = (x + 3 {)}^{2} - 1[/tex]simplifying it yields:
[tex]\implies \boxed{f(x) = {x}^{2} + 6x + 8}[/tex]
Hence,B is our required answer

jack had m math problems to complete during his vacation. he solved the same number of problems every day and finished them all in 5 days. Suppose Jack was solving 15 problems per day. Use this information and the answer to part (a) to build an equation. (the answer too part a was m/5)
Answer:
m/5=15
Step-by-step explanation:
Since Jack was solving m/5 problems per day, the equation to solve this would be the one given above.
The equation that represents the situation is m = 75x.
What is an equation?Two algebraic expressions having the same value and symbol '=' in between are called an equation.
If Jack solved m math problems in 5 days by solving the same number of problems every day, then he solved m/5 problems per day.
Now suppose Jack was solving 15 problems per day.
We want to find out how many problems he had to solve in total, so we can set up an equation using these two pieces of information:
15x = m/5
Here, x represents the number of days Jack took to solve all the problems.
We can solve for m by multiplying both sides of the equation by 5:
75x = m
So the equation we get is:
m = 75x
Therefore, this equation relates the total number of math problems Jack had to solve (m) to the number of days he took to solve them (x), given that he solved 15 problems per day.

Based on the diagram, which expresses all possible lengths of segment AB?
AB = 25
27 < AB < 81
AB = 85
AB < 27 or AB > 81
Answer:
B. 27<AB<81 seems like the best option. AB got to be bigger than 27.
Step-by-step explanation:
Based on the diagram, possible lengths of side AB are 27 < AB < 81.
What is Triangle?Triangle is a polygon in two dimensional geometry. It consists of three sides, three angles and three vertices.
The sum of all the angles inside the triangle is equal to 180 degrees.
We have the Triangle Inequality theorem which states that the third side of a triangle is always less than the sum of the lengths of the other two sides.
So the length of side AB is always less than AC + BC.
AB < AC + BC
AB < 27 + 54
AB < 81
Now from the diagram it is clear that AC is less than AB.
AC < AB
27 < AB
Combining these inequalities, we get 27 < AB < 81.
Hence all the possible lengths of side AB is 27 < AB < 81.

Question
A pole that is 3 m tall casts a shadow that is 1 m long. At the same time, a nearby tower casts a shadow that is 44.5 m long. How tall is the tower?
Answer: 1,33.5 m
Step-by-step explanation:
We can set up a proportion to solve. I will have the length of the pole / tower on the top (numerator), and the length of the shadow on the bottom (denominator). All units will be in m.
[tex]\frac{3}{1} =\frac{x}{44.5}[/tex]
Now, I will cross multiply and solve for x. This will give us the height of the tower.
x * 1 = 3 * 44.5
x = 133.5 m

The table of values shown below represents a linear function. Which of these points could also be an ordered pair in th
table, and why?
The linear function is y = (4/3)x + 3 with a slope of (4/3) and has the point (18, 27)
What is a linear function?A linear function is in the form:
Where m is the rate of change (slope), and b is the y intercept.
From the table, b = 3 (at x = 0, y = 3)
The slope (m) = (7 - 3) / (3 - 0) = 4/3
y = (4/3)x + 3
The point (18, 27):
y = (4/3)(18) + 3 = 27
The linear function is y = (4/3)x + 3 with a slope of (4/3) and has the point (18, 27)

What is congruency?Two figures or objects are said to be congruent in geometry if their shapes and sizes match, or if one is a mirror image of the other. The meaning of congruency is that the two shapes are similar as well as equal in size.
In order for two polygons to be congruent, all corresponding pairs of sides and angles must be equal in measure, but only option B mentions the sides specifically.
Option A only mentions angles, option C mentions a reflection transformation, and option D mention a translation transformation, but neither of them provides enough information to show that all corresponding pairs of sides are equal.

A rectangular garden is 15 ft longer than it is wide. Its area is 700 ft. What are its dimensions?
Step-by-step explanation:
Given :-
The length of rectangular garden is 15 feet longer than its widthThe area of rectangular garden is 700ft²To find:-
Dimensions of rectangular gardenSolution:-
According to the question , let the length of rectangular garden be x and width be x + 15
We know , the formula for area of rectangular garden is L × B
putting the known values ,
700ft.² = X × (X + 15)
700 ft. ² = x² + 15x
x² + 15 x - 700 = 0
By factorising it we get , x = 20
So , the dimensions of rectangular garden are 20 feet and 35 feet respectively for length and width.

Find the area of the figure.
answer:
4.5m²
explanation:
1. find area of the circle
A(circle)=πr²
A=π(2.3²)
A=16.62m²
2. find area of the square
the diameter of a circle is twice its radius. when you multiply 2.3 by two, you get 4.6. since the circle reaches to the sides of the square, the diameter is also the length of a side on the square.
A(square)=s²
A=4.6²
A=21.16m²
3. subtract the two areas
to find the area of the shaded sector, we need to subtract the area of the circle from the area of the square.
A(shaded)=21.16-16.62
A=4.54097487m²
(be sure to round as necessary)

X = (nx₁+mx₂/m+n)
let, the x-coordinate of Q = a
Substitute the given parameters
-1 = 3(-3) + 1(a) / 1+3
