Answer:

S.A = 730mm²

Step-by-step explanation:

Since the solid is made up of two rectangles. Then the surface area (S.A) would be

S.A = area of first rectangle + area of second rectangle

Since the first rectangle has it's base to be 25mm and height to be 21mm, then it's area is

25mm x 21mm = 525mm²

Since the second rectangle has it's base to be 41mm and height to be 5mm, then it's area is

41mm x 5mm = 205mm²

Therefore

S.A = 525mm² + 205mm² = 730mm²

Write an equation that gives the proportional relationship of the graph.
labwork [276]

Answer:

C

Step-by-step explanation:

A proportional graph is a line. Every line has a slope. The slope is found by subtracting two points as a ratio. The line has points (0,0) and (2,6).

6-0 = 6

2 -0 = 2

The ratio is vertical over horizontal so 6/2 = 3.

The equation is y = 3x.

Write the equation of the line that passes through (-4, 3) and is perpendicular to the line y = 7/5x -3/5
tensa zangetsu [6.8K]

Answer:

y = -\frac{5}{7}x + \frac{1}{7}

Step-by-step explanation:

3 = −5⁄7[−4] + b

2 6⁄7

\frac{1}{7} = b \\ \\ y = -\frac{5}{7}x + \frac{1}{7}

Perpendicular Lines have OPPOSITE MULTIPLICATIVE INVERSE <em>RATE</em><em> </em><em>OF</em><em> </em><em>CHANGES</em><em> </em>[<em>SLOPES</em>], so 1 2⁄5 [or 7⁄5] becomes −5⁄7.

I am joyous to assist you anytime.

Plot the zeros of the function and select the correct end behavior of function's graph.
dem82 [27]
<u><em>Answer:</em></u>
As x approaches negative infinity, f (x) approached negative infinity

<u><em>Explanation:</em></u>
The graph of the given function is shown in the attached image.

<u><em>Let's check the options given:</em></u>
<u>Option 1:</u>
<span>As x approaches positive infinity, f(x) approaches negative infinity.
This option is incorrect as we can note that as the value of x increases approaching positive infinity, the value of f (x) also increases approaching positive infinity

<u>Option 2:</u>
</span><span>As x approaches negative infinity. f(x) approaches negative infinity.
</span>This option is correct as we can note that as the value of x decreases approaching negative infinity, the value of f (x) also decreases approaching negative infinity

<u>Option 3:</u>
<span>As x approaches negative infinity, f(x) approaches positive infinity.
</span>This option is incorrect as we can note that as the value of x decreases approaching negative infinity, the value of f (x) also decreases approaching negative infinity

<u>Option 4:</u>
<span>As x approaches positive infinity, f(x) remains constant.
</span>This option is incorrect as we can note that as the value of x increases approaching positive infinity, the value of f (x) also increases approaching positive infinity

Hope this helps :)
