Answer:

  B.  49/2 units squared

Step-by-step explanation:

The area is that of a triangle 7 units wide and 7 units high. Its area is given by the formula ...

  A = 1/2bh

  A = (1/2)(7 units)(7 units) = 49/2 units squared

Answer: 1210.1

Step-by-step explanation:

Step-by-step explanation:

The slope and y-intercept values indicate characteristics of the relationship between the two variables x and y. The slope indicates the rate of change in y per unit change in x.

Answer:

x = 50°

Step-by-step explanation:

the sum of the exterior angles of any polygon is 360°

2x-12 + 32 + 2x + x + 90 = 360

5x + 110 = 360

5x = 250

x = 50

Answer: V = (12in - 2*x)*(8 in - 2*x)*x

Step-by-step explanation:

So we have a rectangular cardboard sheet, and we cut four squares of side length x in each corner so we can make a box.

Remember that for a box of length L, width W and height H, the volume is:

V = L*W*H

In this case, the length initially is 12 inches, but we remove (from each end) x inches of the length, then the length of the box will be:

L = 12 in - 2*x

For the width we have a similar case:

W = 8in - 2*x

And te height of the box will be equal to x, then:

H = x

This means that the volume is:

V = (12in - 2*x)*(8 in - 2*x)*x

Here we can see the connection between the cutout and the volume of the box

4x3 + 3x² – 9x +7

(multiply)

= 12+[tex]3x^{2}[/tex]-9x+7

(calculate)

=19+[tex]3x^{2}[/tex]-9x

(reorder the terms)

= 19+[tex]3x^{2}[/tex]-9x

(Use commutative property to reorder)

= [tex]3x^{2}[/tex]-9x+19

Answer:  [tex]3x^{2}[/tex]-9x+19

Answer: should be 3/5

Step-by-step explanation:

Divide both the numerator and denominator by the GCD

75 ÷ 25

125 ÷ 25 if im wrong sorry

The ratio of 75m : 125cm in its simplest form is 60 : 1.

A ratio is a comparison between two similar quantities in simplest form.

Proportions are of two types one is the direct proportion in which if one quantity is increased by a constant k the other quantity will also be increased by the same constant k and vice versa.

In the case of inverse proportion if one quantity is increased by a constant k the quantity will decrease by the same constant k and vice versa.

Given, Two similar quantities.

We know 75m = 75×100 = 7500 cm.

Therefore, The ratio between them is,

7500 : 125.

1500 : 25.

300 : 5.

60 : 1.

Answer:

Not a function

Step-by-step explanation:

To answer this, we first need to know what a function actually is: A function is a relation between 2 sets which relates the element of the first set to only one element of the second set.

We can see in the provided image that the value -9 is related to 2 values of the second set, hence it is NOT a set.

Another way to think about it is that a function takes an input and gives only one output (where the left set is the input and the right set is the output). Since -9 gives 2 outputs from the given relation, it cannot be a function.

Answer:

The answer is 3.

Step-by-step planation:

All you have to do is find the 2 points and it looks like this:

(-2,-3) , (0,3)

3- -3 /0- -2   = 6/2 = 3

Answer:

Below in bold.

Step-by-step explanation:

m < C = 180 - 43 - 115 = 22 degrees.

Using the Sine Rule:

6 / sin 22 = a / sin 43

a sin 22 = 6 sin 43

a = 6 sin 43 / sin 22

a = 10.92 to 2 DP's.

Applying the same rule  to calculate b:

6 / sin 22 = b / sin 115

b = 6 sin 115 / sin 22

b = 14.52 to 2 DP's.

Step-by-step explanation:

The domain of the function; y=√x+4 as given in the task content is; 0<x<oo.

From the function; y=√x+4 given in the task content; it follows that the domain of the function is the set of all possible values of x.

On this note, the possible values of x from √x includes all positive numbers as any negative value of x renders the a complex number.
