Answer:

a) -0.5 = -1/2

b) -2/1/4 = -2/4

c) -5/6/7 = -5/42

d) 7.2 = 72/10

Step-by-step explanation:

The linear function with the same y-intercept with the graphed function is: table A.

The equation that models a linear function is, y = mx + b, where m is the slope and b is the y-intercept.

Slope of the graphed function = rise/run = - 2/1 = -2

Using one of the points on the line (x, y) = (5, 0) and the slope, m = -2, find the y-intercept (b) by substituting the values into y = mx + b:

0 = -2(5) + b

0 = -10 + b

10 = b

b = 10

The slope (m) of the graphed function is -2, and the y-intercept (b) is: 10.

Slope (m) of table A = change in y/change in x = (14 - 8)/(3 - 1) = 3

Substitute a point (x, y) = (1, 8) and slope (m) = 3 into y = mx + b to find the y-intercept (b):

8 = 3(1) + b

8 - 3 = b

5 = b

b = 5

Therefore the table with the same y-intercept as the graphed function is table A.

The area of the triangle with sides of 51cm, 37cm, and 30cm, is calculated to be 496.37cm².

The area of a triangle can be computed by the formula √{s(s - a)(s - b)(s - c)}, where a, b, and c, are the three sides of the triangle, and s is the semi-perimeter of the triangle, that is, s = (a + b + c)/2.

In the question, we are asked to find the area of the triangle, whose sides are 51cm, 37cm, and 30cm.

Thus, we take a = 51cm, b = 37cm, and c = 30cm.

The perimeter of the triangle = a + b + c = 51cm + 37cm + 30cm = 118cm.

Hence, the semi-perimeter of the triangle, s = (a + b + c)/2 = 118cm/2 = 59cm.

Hence, using the formula for the area of the triangle:

√{s(s - a)(s - b)(s - c)}

= √{59(59 - 51)(59 - 37)(59 - 30)} cm²

= √{59 * 8 * 18 * 29} cm²

= √246384 cm²

= 496.37 cm².

Thus, the area of the triangle with sides of 51cm, 37cm, and 30cm, is calculated to be 496.37cm².

Answer:

√2

Step-by-step explanation:

Angle ( θ ) = 45

Hypotenuse side = 2

Opposite side = x

Formula : -

sin θ = Opposite side / Hypotenuse side

Note :

The value of sin 45 = 1/√2

sin 45 = x/2

1/√2 = x/2

Cross multiply,

x*√2 = 2*1

x√2 = 2

2 can be simplified as √2 * √2

x√2 = √2*√2

Divide √2 on both sides,

Answer:

h = 2.5cm or 5/2 cm

Step-by-step explanation:

Vol = Basearea•h

In your question, the base is the triangle shape. The rectangles go around the sides of the 3-d shape and on top is another triangle that we can't really see. In your image it is kind of laying on its side. So if we stand it up properly, the triangles are on the top and bottom. The triangle is the base.

Volume was given; it is 35. Also given is one side of the rectangles, that is 7.

So we can fill in 35 and 7 into the volume formula and calculate the Basearea.

V = B • h

35 = B • 7

35 = 7B

Divide by 7.

5 = B.

We have calculated the Basearea. This is the area of the triangle shaped bottom. The area formula for a triangle is:

A = 1/2bh

We just found that A=5 and we were given that the base of the triangle is 4.

A = 1/2bh

5 = 1/2•4•h

5 = 2h

Divide by 2.

5/2 = h

This is the height of the triangle, h in the picture. (The h in the volume formula and h in the triangle are different)

This is what the question is asking for, h = 5/2 or in decimals, h = 2.5cm

Answer:

Increasing: [tex](\infty, -1) \cup (2, \infty)[/tex]

Decreasing: [tex](-1, 2)[/tex]

Step-by-step explanation:

So when an equation has and odd degree, it will go in the opposite direction on both ends, so if y went towards infinity as x went towards infinity, then y would go towards negative infinity as x goes towards negative infinity. In this case, by looking at the graph it has an odd degree, due to opposite end behaviors, although on both ends it's increasing because even though it appears that it's going down on the left side, that's only if you start from the right and go towards the left. So it's really increasing from negative infinity to -1, and then it decreases from -1 to 2, until it once again starts increasing from 2 to infinity. This can be represented as (-infinity, -1) U (2, infinity) for increasing and (-1, 2) as decreasing

from (1)

x = 16 - y

Substitute into (2)

0.02x + 0.66y = 0.47 × 16
