Work out the value of x - y

Answer:

Your answer is B. I had some help from my mom.

Step-by-step explanation:

the average rate of change on the interval [1, 2] is found by computing

 (f(2) - f(1))/(2 - 1)

 = ((4^1+2) - (4^0+2)/1

 = (6-3)

 = 3

Answer:

[tex] {6}^{2} \times \pi \times 15 + \frac{1}{2} \times \frac{4}{3} \times \pi \times {6}^{3} = 19 \times {6}^{2} \times 3.14 = 2147.76[/tex]

Answer:

Step-by-step explanation:

Hemisphere Formula: ( 2 / 3 ) πR = V

Substitution: ( 2 / 3 ) 3.14 * 6 = 12.56

Cylinder Formula: πR^2 * H = V

Substitution: 3.14 * 6^2 * 15 = 1695.6

1695.6 + 12.56 = 1708.16

Step-by-step explanation:

I think the question must be which of the following is not a line segment shown in drawing........

Because three of them are and one isn't. If the question is that, then the answer is LJ.

Answer:

The area of the cube is equal to [tex]0.375\ \text{foot}^2[/tex].

Step-by-step explanation:

The formula for the surface area of a cube is :

[tex]A=6s^2[/tex]

Where

s is the cube's side length

Put s = 1/4 foot

So,

[tex]A=6\times (\dfrac{1}{4})^2\\A=0.375\ \text{foot}^2[/tex]

So, the area of the cube is equal to [tex]0.375\ \text{foot}^2[/tex].

Step-by-step explanation:

Answer: 70.77 or 71 if rounded up

Step-by-step explanation:

Add all the scores then divide to 18.

Answer:

(2, -1)

(10, 15)

Step-by-step explanation:

Subtract the second equation from the first

  y = x² – 10x + 15

- (y =           2x – 5)

————————————

 0 = x² - 12x + 20

Factor

(x  - 2)(x - 10) = 0

x = {2, 10}

-------------------

For x = 2

y = 2(2) - 5

y = -1

Solution 1

(2, -1)

----------------------

For x = 10

y = 2(10) - 5

y = 15

Solution 2

(10, 15)

Answer:

25 in^2

Step-by-step explanation:

So the area of a triangle is (Base * Height) / 2. The base, which is where the triangle "sits" is 10 in. The height is 5 in.

With this, these numbers can both be plugged in to get the answer:

(10 * 5) / 2

50/2

25 in^2

It is squared after the units since it is the area.

SAS   because its is side angle side for both of them

Answer:

SSS (Side-Side-Side)

Step-by-step explanation:

It is given that PS ≅ RQ. Shown by congruency symbols, PR ≅ RQ. Lastly, QR ≅ QR due to the reflexive property.

Due to all three sides between the two triangles being congruent, you can conclude that they are congruent by SSS, or Side-Side-Side.

Answer:

x if -3is less than x is less than -1

5 is -1 is less than x is less than 1

Step-by-step explanation:

You find the slope of the line for the first piece when the x-values range from -3 to -1.

For the second piece, the line is y=5 because the line is horizontal.

Answer:

x+3; 5

Step-by-step explanation:

The first piece, shows the diagonal part in Quadrant II.

The line segment is colinear with the line y=x+3, because the slope is 1, and the y-intercept is 3. So the piece would be defined as x+3.

The second line segment is the flat one, which has a slope of 0 and its y-intercept is 5. So the piece would be defined as 0x+5 or 5

What is the angle of elevation θ that is required for a hit ball to just clear the center field fence when it is hit 2 ft above the ground? Show all of your work and round your answer to the nearest hundredth of a degree.

Distance from Home plate to the center field fence: 425 ft

Height of the center field fence: 8 ft

____________________________

ANSWER:

The fence height = 8ft

The fence height takes 2 ft from the ground and doesn't count towards the angle.

Therefore subtract the difference = 8-2 = 6ft

The fence height from the 2ft to the fence top = 6ft

Angle of elevation (θ):

Tan(θ) = opposite/adjacent

Adjacent = Distance from Home plate to the center field fence = 425 ft

Opposite = 6ft

Answer:

The ratio of student to teacher is 12.3 to 1

Answer:

C.

2z2; –5

Step-by-step explanation:

Add and subtract the second term to the expression and factor by grouping.

( z + 6 ) ( 2 z 2 − 5 )

Answer:

2z^2; –5

Step-by-step explanation:

2z3 = 2 • z • z • z 12z2

= 2 • 2 • 3 • z • z

The GCF is 2z2.

–5z3 = –1 • 5 • z • z • z

–30 = –1 • 5 • 6

The GCF is –5.

Answer:

Option C: b is parallel which is; y = ½x - 1

Step-by-step explanation:

We know that if the slope of a line is m, then the slope of the line that is perpendicular to it would have be; -1/m.

In this question, m = ½

Thus, the slope of the line that is perpendicular to it is; -1/(½) = -2

However, to find the slope of the line parallel to it would mean that the value of m which is the original slope will remain the same. Original slope = ½, thus the only option with slope as ½ is option C where b is parallel with the equation; y = ½x - 1

False. Obtuse is always greater than 90°.

Answer:

False

Obtuse triangles can't have right angles

Answer:

Using the "AC Method" I got (w - 2) (w + 9)

Step-by-step explanation:

Answer:

(w−2)(w+ 9)

Step-by-step explanation:

Grouping

Step 1:

Use the sum-product pattern

w²  + 7 − 18

w² + 9 − 2 −18

Step 2:

Common factor from the two pairs

w²+ 9 − 2 − 18w

( w+ 9) − 2( w+ 9)

Step 3:

Rewrite in factored form

(w + 9) − 2( w+ 9)

(w−2)(w+9)

We know that,

In a right-angled triangle,

Hypotenuse ² = Base ² + Height ²

1 – 10 ² = 6 ² + X ²

Or, X ² = 10 ² – 6 ²

Or, X ² = 100 – 36

Or, X ² = 64

Or, X = √ 64

Or, X = 8 Units

2– X² = 7² + 3²

Or, X² = 49 + 9

Or, X² = 58

Or, X = √58

Or, X = 7.61 Units ( Approx )

3 – 15 ² = EF ² + 9

Or, EF² = 15 ² – 9 ²

Or, EF ² = 225 – 91

Or, EF ² = 134

Or, EF = √ 134

Or, EF = 11.6 Inches ( Approx)

.II} 1 – Here the length of the ladder will be the hypotenuse.

Hence, Hypotenuse = 13 Metre

.Now, The vertical wall will be the height.

Hence, Height = 12 Metre

Distance of the foot of the ladder to the wall will be the base.

Let base be B.

Now, Hypotenuse ² = Base ² + Height ²

Or, 13² = B² + 12²

Or, B² = 13² – 12²

Or, B² = 169 – 144

Or, B² = 25

Or, B = √25

Or, B = 5 Metre

Hence, the distance of the foot of the ladder from the wall is 5 metre apart.
