Pls help! Error Analysis problem

Answer:

a and c

Step-by-step explanation:

so we know that -2 is the greatest number in this inequality and with that, the 'equation' would look like this-

x<-2

now let us solve a-d-

0.25-2.50=-2.50

-4.25-(-2.75)=-1.5

-3.25-1.75=-5

-4.50-(-5.25)=0.75

**with negative numbers the 'smaller' the number is the greater it actually is ex. -2.50<-1** it works this way because the 'larger' the number gets the further away it becomes from 0 or whole numbers making it smaller than the negative numbers closer to zero such as -1**

hopefully, that makes sense

now let us see which equations fit our inequality- **we'll let the bolded ones mean that they fit the inequality**

a)-2.50<-2

b)-1.5<-2

c)-5<-2

d)0.75<-2

good luck :)

i hope this helps

brainliest would be highly appreciated

have a nice day!

Answer:

= 50% decrease

Step-by-step explanation:

There is a percentage decrease of 50% in the number of people from 72 people to 36 people

An equation is an expression used to show the relationship between two or more numbers and variables.

There is a change of 72 people to 36 people, hence:

Percentage change = [(36 - 72) / 72] * 100% = -50%

There is a percentage decrease of 50% in the number of people from 72 people to 36 people

Answer:

B

Step-by-step explanation:

I put A and got it wrong. The correct answer is B.

The function has a range of f(x) ≤ 3/4 is f(x) = -x² + 3/4.

An function is an expression that shows the relationship between two or more numbers and variables.

The range of a function is the set of all output variables.

From the graph plotted;

The function has a range of f(x) ≤ 3/4 is f(x) = -x² + 3/4.

Answer:

It equals 97°

Step-by-step explanation:

The mistake she made was she thought angle t was vertical to angle u and thus it has the same value. Vertical angles have to be across from each other and not on top of each other. So why does it equal 97? If we look at angle y it has the same value and the angles are exactly the same. Look below for the other explanation since it can't really be said by words.

Answer:

[tex]\displaystyle f(x)=-\frac{1}{24}\left(x-12\right)^2+6[/tex]

Where f(x) models the height, in inches, of the frog's leap after it had leapt x inches.

Step-by-step explanation:

We are given that a frog leaps two feet, with the highest point in the jump being six inches.

Assuming the frog starts at (0,0), we want to find a quadratic function in vertex form for the path of the jump.

First, we will convert the length of the jump to inches. Two feet is equivalent to 24 inches.

Next, since the frog started at (0, 0), in order to jump a length of 24 inches, it must have ended at (0, 24). These two points will also be our two roots: x = 0 and x = 24. We can use the factored form of a quadratic:

[tex]f(x)=a(x-p)(x-q)[/tex]

Where p and q are the roots.

Substitute in the roots:

[tex]f(x)=a(x-0)(x-24)=ax(x-24)[/tex]

Now, since the frog reached a maximum height of six inches, the y-coordinate of the function at its vertex point is 6.

Since a parabola is symmetrical along its axis of symmetry, the axis of symmetry is always halfway between the two roots.

Therefore, the x-coordinate of our vertex is:

[tex]\displaystyle x=\frac{24-0}{2}=12[/tex]

So, when x = 12, f(x) = 6. Substitute:

[tex]6=a(12)(12-24)[/tex]

Solve for a:

[tex]\displaystyle- 144a=6\Rightarrow a=-\frac{1}{24}[/tex]

Therefore, our function is:

[tex]\displaystyle f(x)=-\frac{1}{24}x(x-24)[/tex]

Now, we can place this into vertex form:

[tex]\displaystyle f(x)=a(x-h)^2+k[/tex]

Where a is the leading coefficient and (h, k) is the vertex.

Our leading coefficient is -1/24, and the vertex is (12, 6). Hence, our function is:

[tex]\displaystyle f(x)=-\frac{1}{24}\left(x-12\right)^2+6[/tex]

Where f(x) models the height, in inches, of the frog's leap after it had leapt x inches.

Answer:

1. 454

2. 96

Step-by-step explanation:

1. To find The surface area, find the are of each side. The bases of the triangular prism have the same surface area,

Surface area of triangle: 1/2b*h, half of the base times the height. base = 8, height = 10, 1/2(8) * 10 = 4*10 = 40, the other side has the same area, so double it to get 80.

The surface area of one of the rectangle is 11*14, another is 12*11, and the last is 11*8, multiply all to get 154, 132, and 88, and 154 + 132 + 88 + 80 = 454

2. The two triangles is 1/2b * h, b = 6, h = 2, 1/2(6) * 2 = 3*2 = 6, double it because there is another triangle to get 12

The three rectangles are 3*7 + 3*7 + 6*7 = 21 + 21 + 42 = 84, 84 + 12 = 96

Answer:

D. (-7,0)

Step-by-step explanation:

If The two intercets are (5,0) and (-5,0) then (-7,0) will be an x-intercept.

Answer:

d.(-7,0)

Step-by-step explanation:

'd' is the correct answer because just as how the y-intercept has to look something like this: (0,5) as in the given 'x' point is 0 the x-intercept  has to look the exact same as well (other than the fact that it's now the x-intercept instead of y.) so it would have to be that the x-axis' point can be any number that isn't 0 and the y-axis' point must always be 0.

good luck :)
