Answer:

cos

Step-by-step explanation:

take 31 degree as reference angle

using cos rule

cos 31=adjacent/hypotenuse

0.85=14/x

x=14/0.85

x=16.47

x=16.5

Pls help :( The graph shows the relationship between a puppy’s weight y, in ounces, and time x, in months, as it grows. Which fu
Ulleksa [173]

Answer:

c y=6x+4

Step-by-step explanation:

y=mx+b.  m= slope b= y intercept

at x=0, the graph is at y=4, so that is b. Slope is up/over. so from point (0,4) to point (2,16), the graph went up 12 and over 2. 12/2=6

Inverse variation?
Alex_Xolod [135]

Answer:

An Inverse variation states that a relationship between two variables in which the product is always constant.

If one of the variable increases then the other decreases in proportion so that the product is unchanged.

if y is inversely proportional to x, then the equation is of the form

y = \frac{k}{x} , where k is constant.

As per the given condition, A constant force acts upon an object, the acceleration of the object varies inversely with it's mass.

i.e, a \propto \frac{1}{m}

By definition of inverse variation;

a = \frac{F}{m} . ......[1]  ,where F is the constant force.

It is given that an object has mass(m)= 4kg and the acceleration of an object(a) = 14 m/s^2

Substitute these in [1] to find the constant force F;

14 = \frac{F}{4}

or

F =14 \times 4 = 56 kg m/s^2

Now, if the same force acts upon the another object whose mass (m) = 7 kg then calculate acceleration.

[1]⇒  a = \frac{56}{7} = 8 m/s^2

therefore, the acceleration of an another object is, 8 m/s^2

Mrs.Smith has two similiar recycling bins in her office. The dimension of the smaller bin can be found by dilating the dimension
nikklg [1K]

Answer:

The dimension of the larger bin is x and the smaller bin is 0.75x.

Step-by-step explanation:

Let the dimension of the larger bin is x.

It is given that the dimension of the smaller bin can be found by dilating the dimension of the larger bin by a scale factor of 0.75

In order to find the dimension of the smaller bin multiply the dimension of the larger bin by 0.75

(x)(0.75)=0.75x

Hence, the dimension of the larger bin is x and the smaller bin is 0.75x.
