Help me please with math

Mathematics
1 answer:
Mashcka [7]3 years ago
5 0

Step-by-step explanation:

We know that the pythogoras rule says that

{h}^{2}  =  {p}^{2}  +  {b}^{2}

<h3> In the first diagram,</h3>

The Hypotenuse is already provided so we can find the answer easily :)

<h2>Let's solve!!</h2>

1) Let the unknown length(i.e. the base ) be x² yd.

<h3>According to the question</h3>

{h}^{2}  =  {p }^{2}  +  {b}^{2}

{15}^{2}  =  {12}^{2}  +   {x}^{2}

225 = 144 +  {x}^{2}

=  {x}^{2}  = 225 - 144

=  > {x}^{2}  = 81

=  > x =  \sqrt{81}  = 9

Hence the base of the first figure is 9 yd.

Let's solve this as well!!

2) Let the hypotenuse be x.

{h}^{2}  =  {b}^{2}  +  {h}^{2}

{x}^{2}  =  {2}^{2}  +  {5}^{2}

=  {x}^{2}  = 4 + 25

=  {x}^{2}  = 29

= x =  \sqrt{29}

x = 5.3851648071345

<h3>So therefore the unknown side is 5.3851648071345 in</h3>

Hope it helps you!!

Simplify the expression: 4(10 + 6u)
Marianna [84]

Answer:

24u + 10

Step-by-step explanation:

first rearrange the terms

4(10+6u)

4(6u+10)

then distribute the 4

4(6u) = 24u

4(10) = 10

then you get 24u + 10

In two or more complete sentences, define the key features of the graph below and explain how to write its equation using functi
Korolek [52]
The graph has a vertex at (3, -2). It extends upward from there linearly at a slope of -1 to the left and 1 to the right. It is the graph of an absolute value function. If we assume it keeps extending upwards the domain is all real numbers. (which is what i would assume even though there's no arrows it doesn't have decipherable endpoints). The range is y ≥ -2 with y -intercept (0,1), and x-intercepts: (5,0) & (1,0).

To write the equation for this function, I would acknowledge that it is the translation of the graph of the standard absolute value function: f(x) = |x| ; right 3 and down 2. Which would be to subtract 3 from x and subtract 2 from the end.

Through: (3, 4), slope = -2​
sineoko [7]

Answer:

y = -2x - 2

Step-by-step explanation:

Slope-Intercept Form: y = mx + b

Points: (3, 4)

Slope: -2

y = -2x + b

4 = -2 ( 3 ) + b

4 = -6 + b

b = -2

y = -2x - 2
