Find sin(β) in the triangle.

Pachacha [2.7K]

Answer:

4/5

Step-by-step explanation:

<u>Given </u><u>:</u><u>-</u><u> </u>

A right angled triangle with sides as 3 , 4 and 5 cm .

We need to find the value of sin(β) in the given triangle . We know that the ratio of sine is ,

$:\implies$ sin(β) = p/h

Where p is perpendicular and h is hypontenuse.

$:\implies$ sin(β) = 4/5

<h3>Hence the required answer is 4/5.</h3>

Which statement is true about the y-intercept of a quadratic function?

Dafna11 [192]

Answer:

A.

Step-by-step explanation:

A quadratic function may only intercept the y-axis once. This is because the definition of a y-intercept tells us that it is the point where x = 0. If there are multiple points where x = 0, then the expression cannot be a function. As such, a quadratic function can only have one.

Choice B contradicts the previous statement.

Choice C is wrong because the x-intercept is the zero of the function. This is because at a given x-coordinate that touches the x-axis, the y-coordinate will be 'zero'.

Choice D is wrong because the y-intercept is where x = 0.

I hope this helps!

The useful life of a certain piece of equipment is determined by the following formula: u=(8d)/h^2, where u is the useful life o

Anni [7]

Answer:

The correct answer is E.

Step-by-step explanation:

First I look for the relationships between the coefficients. The first term corresponds to the base value.

$\frac{8*d}{h^{2}} = \frac{8}{1} * \frac{d}{h^{2} }$

The second term corresponds to the value obtained when the density of the underlying material is doubled and the daily usage of the equipment is halved.

$\frac{2*8*d}{(0,5*h)^{2}} = \frac{16*d}{0,25 * h^{2}} = \frac{16}{0,25} * \frac{d}{h^{2} }$

With the I get the ratio of coefficients of $\frac{d}{h^{2}}$ :

$\frac{8}{1}$ = 8

$\frac{16}{0,25}$ = 64

Now I calculate the percentage increase in the useful life of the equipment as:

% = $\frac{64}{8}$ * %100 = %800

Which ordered pair is a solution to the linear inequality below?

Igoryamba

Answer:

B

Step-by-step explanation:

The inequality is

3x-5y>=10

You can substitute each of the choices in the inequality (on the left side) to see if the result is >=10.

A: 3(1)-5(4)=3-20=-17 not good.

B: 3(6)-5(-3)=18+15=33 good

Nethan made eight rose bouquets and six daffodil bouquets. Nethan only has enough flowers to make at most 20 rose or daffodil bo

Igoryamba

I<span> found the graph choices: </span>

<span>Given:</span>
8 rose bouquets
6 daffodil bouquets
total of 14 bouquets

enough flowers left to make maximum of 20 bouquets.

x = additional rose bouquets
y = additional daffodil bouquets

20 maximum bouquets - 14 made bouquets = 6 additional bouquets

x + y = 6

y = 6 - x
x = 6 - y

If x = 0 then y = 6
If x = 6 then y = 0
If x = 4 then y = 2
If x = 2 then y = 4

Pls. see attachment for the correct graph.
