the situation.

Answer:

-5

Step-by-step explanation:

since the formula for slope intercept form is y=mx+b

and mx stands for slope and b stands for the y-intercept the y-intercept would be -5

I'm certain that the answer is -5

Answer:

Level 2:

45 x 45 = 2025

28 x 28 = 784

2025 + 784 = 2809

(sqrt)2809 = 53

53 units

Level 3:

(Start by graphing the coordinates)

Your shape should have one leg of 14 units, and one leg of 8 units.

14 x 14 = 196

8 x 8 = 64

196 + 64 = 260

(sqrt)260 = 16.1245155

(rounded to nearest tenth)

16.1 units

I`m not sure about the other two though, sorry :/

3. Using the Pythagorean theorem, x = 53 in.

4. 6, 9, and 11 does not form a right triangle because they are not a Pythagorean triple. i.e. 11² ≠ 9² + 6².

5. Using the distance formula, AB = 16.1 units

7. Height of the Pyramid using the Pythagorean theorem is: h = 5.2 units.

8. Length of diagonal = 10.2 units.

If c is the hypotenuse of a right triangle with a and b as its legs, the Pythagorean theorem states that c² = a² + b².

Diagonal (d) = √(l² + h² + w²)

l = length

w = width

h = height

3. Find x using the Pythagorean theorem:

x = √(45² + 28²)

x = 53 in.

4. 6, 9, and 11 does not form a right triangle because they are not a Pythagorean triple. i.e. 11² ≠ 9² + 6².

5. Using the distance formula, find AB:

AB = √(5−(−3))² + (6−(−8))²

AB = √260

AB = 16.1 units

7. Height of the Pyramid using the Pythagorean theorem:

h = √(6² - 3²)

h = 5.2 units.

8. Diagonal of the Rectangular Prism:

Length of diagonal = √(l² + h² + w²) = √(8² + 5² + 4²)

Length of diagonal = 10.2 units.

Answer:

Q1: No solutions

Q2: x=2, y=-2

Q3: x=1, y=4

Step-by-step explanation:

Q1: Found out 0y = 18 which is impossible therefore no solution.

Q2:

In the first equation: [tex]2x - 4y = 12[/tex]

Let's express x in terms of y by changing the subject. Follow my steps.

[tex]2x = 12+4y[/tex]

[tex]x = \frac{12+4y}{2}[/tex]

Now let's put the x above into the second equation: [tex]-14x-4y=-20[/tex]

It becomes: [tex]-14(\frac{12+4y}{2})-4y=-20[/tex]. Follow my steps.

[tex]-7(12+4y)=-20+4y[/tex]

[tex]-84-28y=-20+4y[/tex]

[tex]-32y=64[/tex]

[tex]y=-2[/tex]

Put y = -2 into the first equation:

[tex]2x-4(-2)=12[/tex]

[tex]2x+8=12[/tex]

[tex]2x=12-8[/tex]

[tex]2x=4[/tex]

[tex]x=2[/tex]

Q3:

Multiply the first equation by 3 and the second equation by 7, so that both are 21x.

1st equation:
[tex]3(7x-3y)=3(-5)[/tex]
[tex]21x-9y=-15[/tex]

2nd equation:

[tex]7(3x+2y) = 7(11)[/tex]

[tex]21x+14y = 77[/tex]

We can now substract the 2nd equation with the 1st equation so that both 21x cancels out and only the variable y remains.

[tex]21x-9y-(21x+14y)=-15-77[/tex]

[tex]21x-9y-21x-14y=-92[/tex]

[tex]-23y=-92[/tex]

[tex]y=4[/tex]

Put y = 4 into the second equation to find x.

[tex]3x+2(4)=11[/tex]

[tex]3x+8=11[/tex]

[tex]3x=11-8[/tex]

[tex]3x = 3[/tex]

[tex]x=1[/tex]

Step-by-step explanation:

because both of them are horizontal straight lines

The sum of forty-five and a number n is 46.1, and the expression that can represent this can be written "45+n" where the value of n is 1.1

In mathematics, an expression is defined as a set of numbers, variables, and mathematical operations formed according to rules dependent on the context.

The statement that is given to us is" the sum of forty-five and a number", therefore, the expression that will represent this can be written as,

45 + n,

Now, if the value of n is 1.1. Then the sum will be,

[tex]45+n\\\\=45+1.1\\\\=46.1[/tex]

Hence, the sum of forty-five and a number n is 46.1, and the expression that can represent this can be written "45+n" where the value of n is 1.1

Answer:

Write the equation of the line parallel to x = 5 that passes through (2, 7)

Answer:

Step-by-step explanation:

When you list the trigonometic ratios for both acute angles in a right triangle, you notice some interesting developments.

Let's concentrate on sine and cosine:

Observation from the table above: notice1

In a right triangle, the sine of one acute angle, A, equals the cosine of the other acute angle, B.

If ∠A and ∠B are the acute angles of a right triangle,

sin A = cos B

Since the measures of these acute angles of a right triangle add to 90º, we know these acute angles are complementary. ∠A is the complement of ∠B, and ∠B is the complement of ∠A.

If we write, m∠B = 90º - m∠A    (or m∠A = 90º - m∠B ), and we substitute into the original observation, we have:

      notice4

If θ is substituted for m∠A , we establish the following relationship between sine and cosine:

sincosrule

The sine of any acute angle is equal to the cosine of its complement.

The cosine of any acute angle is equal to the sine of its complement.

Sine and cosine are called "cofunctions", where the sine (or cosine) function

of any acute angle equals its cofunction of the angle's complement.

FYI: What about tangent?

Yes, there is a "relationship" regarding the tangent of the two acute angles (A and B) in a right triangle. It is not, however, the same type of relationship that exists between sine and cosine.

The tangent of ∠A is the reciprocal (flip over) of the tangent of ∠B.

The angles being used in the following examples are acute angles.

ex1

If sin 30º = ½ and cos θ = ½,

find θ.  Solution: Since both trig functions = ½,

30º and θ must be complementary.

θ = 60º

ex2

If sin(3x + 10)º = cos(x + 24)º,

find x.  Solution: In order for the sine and cosine to be equal, the angles must be complementary.

3x + 10 + x + 24 = 90

4x + 34 = 90

4x = 56

x = 14

ex3

If sin(15º) = 0.26 and

cos (15º) = 0.97,

find sin(75º) and the cos(75º).  Solution: The sine of an angle and the cosine of its complement are equal.

15º and 75º are complementary.

sin(75º) = cos(15º) = 0.97

cos(75º) = sin(15º) = 0.26

ex4

In right ΔABC, m∠C = 90º,

sin A = x + 0.1 and cos B = 2x - 0.4. Find x.  Solution: If A and B are the acute angles of a right triangle, sin A = cos B.

x + 0.1 = 2x - 0.4

0.5 = x

So a batch is 5/8

There are THREE 3/4th cups of flour in the cupboard.

So 3 three fourths so basically
3/4 * 3 = 9/4 or

3/4 + 3/4 + 3/4 = 9/4

9/4 and each batch is 5/8.
9/4 ÷ 5/8 = 72/20 or 3 1/10

5 times a number subtracted from another number divided by 3.

Step-by-step explanation:

Answer:

13/45

Step-by-step explanation:

9 times 5 is 45 and 15 times 3 is also 45 after 5 times 5 is 25 and 4 times 3 is 12

25/45- 12/45= 13/45

(because u only have to subtract 12 from 25)

The vertex form of the function g(x)=40x-4x² is g(x) = 4(x + 5)² - 100, where the vertex lies at (-5, -100).

The  general equation of a parabola is given as,

y = a(x-h)² + k

where,

(h, k) are the coordinates of the vertex of the parabola in form (x, y);

a defines how narrower is the parabola, and the "-" or "+" that the parabola will open up or down.

As we want to write a function g(x) = 40x + 4x² in vertex form, and we know that the vertex form of a parabola, with vertex at (h,k) is written as,

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

Also, the algebraic identity  [tex](x + a)^2[/tex] is written as,

[tex](x + a)^2 = x^2 + 2ax + a^2[/tex],

Therefore, [tex]x^2 + 2ax[/tex] can be written as

[tex]x^2 + 2ax = (x + a)^2 - a^2[/tex]

Further, we try to write the g(x) in the vertex form it can be written as,

[tex]\begin{aligned}g(x) &= 4x^2 + 40x\\\\ &= 4[x^2 + 10x]\\\\ &= 4[(x + 5)^2 - 5^2]\\\\ &= 4(x + 5)^2 - 100\\\end{aligned}[/tex]

Hence, the vertex form of the function g(x)=40x-4x² is g(x) = 4(x + 5)² - 100, where the vertex lies at (-5, -100).

Answer: 2016 in^2

Step-by-step explanation:

3) Let's start with the taller rectangular prism. The height is 24", the width is 12", and the length is 12". The smaller rectangular prism is actually a cube because the height, width, and length are all 12". Just as a refresher, the surface area of an object is only the area of each outside face. For rectangular prisms, the surface area is 2(lh+wh+lw) (l=length, h=height, w=width). And for cubes, the surface area is 6s^2, where s is the side. 2(12*24+12*24+12*12) is equal to 1440 inches squared, however, half of one face is covered. This is the longest face shaded in dark green: 24" times 12", but because only half is showing, it is 24*12 divided by 2. This is equal to 144"; and you must subtract this from the entire surface area to account for that covered space. 1440-144 is 1296 inches squared. The cube is (12*12)(6) which is 864. But one whole side is covered, meaning you need to subtract 144 to have the surface area be 720 inches squared. 1296 plus 720 is 2016 inches squared. Decounting the half a side from the prism and one full side from the cube, there are only 10 and a half sides shown.

Hope this helps :)
