Answer:

Its 2 because if you put it ibn your calculator then it's 2

Step-by-step explanation:

Answer:

y = - 4x - 7

Step-by-step explanation:

Line is passing through the point (-1, - 3) and has a slope (m) = - 4

[tex]y - ( - 3) = - 4 \{x - ( - 1) \} \\ \\ y + 3 = - 4(x + 1) \\ \\ y + 3 = - 4x - 4 \\ \\ y = - 4x - 4 - 3 \\ \\ y = - 4x - 7[/tex]

Answer:

Step-by-step explanation:

[tex]19y^{2} + 95y[/tex]

Both terms have a [tex]y[/tex] in them, so we can first start by factoring that out:

[tex]y(19y + 95)[/tex]

For the remaining two terms in the parenthesis, they both can have a [tex]19[/tex] factored out:

[tex]y(19 * y + 19 * 5)[/tex]

[tex]19y(y + 5)[/tex]

Answer:

Step-by-step explanation:

A function can only have one y value for any given x value. If there is more than one value of y for a single x value it is said to have failed the ‘vertical line test.

Since there are points (-7,8) and (-7,-3) this is NOT a function.

Answer:

A) 3.44 ft²

Step-by-step explanation:

before cutouts, the area was 4 x 4 = 16 ft²

the circles have a diameter of 2 ft each, and a radius of 1 ft

each circle has an area pf (3.14)(1²) = 3.14 ft²

3.14 x 4 = 12.56 ft²

16 - 12.56 = 3.44 ft² left

Answer:area of 4 equal circle having

Diameter =2ft

Therefore radius =r=2/2=1ft

Area of 4 equal circle =4(πr²) =4π×1²=4πft²

Area of square=length²=4²=16

Area of shaded region =area of square-

area of 4 equal circle

=16-4π=3.43362938564ft²

Answer:

20 feet

Step-by-step explanation:

Lance the alien is 5 feet tall. His shadow is 8 feet long. At the same time of day, a tree's shadow is 32 feet long. What is the height of the tree?

We solve this using proportion of

Height/ Shadow

= 5/8 = x/32

Cross Multiply

8x = 5 × 32

x = 5 × 32/8

x = 20 feet

The height of the tree is 20 feet

The answer of this question is 12, 15, 20 .

Answer: there is no solution

Step-by-step explanation: 1/4z — 13 is not the same as 1/4 + 13

Say z = 1 that would simplify as -12 3/4 = 13 1/4 they are not the same so there is no solution

Answer:

Step-by-step explanation:

150 + 150 + x = 360

x = 60

∠ADC = 60°

they are the same

Answer:

the greater the number pf Zeroes after the point, the lower the value of the number, so option 11.003

Answer:

The height is 4.

Answer:

1) [tex]49 {a}^{2} - 16 {b}^{2} [/tex]

2) [tex]251502[/tex]

Step-by-step explanation:

a) Question :-[tex](7a - 4b)(7a + 4b)[/tex]

Identity used here :-[tex](a + b)(a - b) = {a}^{2} - {b}^{2} [/tex]

So,

[tex](7a + 4b)(7a - 4b)[/tex]

[tex]=> {(7a)}^{2} - {(4b)}^{2} [/tex]

[tex]=> 49 {a}^{2} - 16 {b}^{2} [/tex]

b) Question :- [tex]501 \times 502[/tex]

Identity used here :-[tex](x + a)(x + b) = {x}^{2} + (a + b)x + ab[/tex]

So,

[tex]501 \times 502 = (500 + 1)(500 + 2)[/tex]

[tex] = > {(500)}^{2} + (1 + 2)500 + 1 \times 2[/tex]

[tex] = > 250000 + 1500 + 2[/tex]

[tex] = > 251502[/tex]

Answer:

Step-by-step explanation:

1. I can't see the first one very well.

2. Find the area of each triangle by doing 1/2 * base * height. This should give you [tex]40m^{2}[/tex]

3. The area of a trapezium is [tex]\frac{1}{2} (a+b)h[/tex] where a is the top edge, b is the bottom edge and h is the height.

We can work out the bottom edge using pythagoras - split the trapezium into 2 triangles on each side and a rectangle in the middle. This gives you the length of the bottom edge which is 2 + 2 + 2 = 6'

Work out the area by doing 1/2(2+6)4 = 16' squared.

4.Split this shape into a triangle and rectangle. We know the right hand edge of the triangle= 9-4 = 5'.

To find the bottom edge of the triangle, use tanθ=opposite/adjacent line. Therefore tan45=bottom edge of triangle/5'. tan 45=1 therefore bottom edge = 5'.

The bottom edge of triangle gives us the height; use 1/2(a+b)h to work out the area of the trapezium. 1/2(4+9)5 = 32.5' squared

Answer:

4.18 × 10^ 2

Step-by-step explanation:

Answer:

Step-by-step explanation:

I am assuming that number began with a decimal point.

Count how many places the decimal must move to the right to get past the 4, in this case the decimal must move 5 places. This means you are multiplying by 10^5. So the number in scientific notation becomes

4.18X10^(-5)

The first option is correct. As long as the signs remain the same for the specific terms, it's correct.

x+y+z is equivalent to z+y+x
