Please help 20 points

Answers

Answer:

(4,2)

Step-by-step explanation:

I am not able to see your screen well but these are the points that I saw in the beginning for E. 8,4. Your x value is either left or right and your y value is up and down. I saw 8 units right and 4 u it's up. Now your scale factor is 1/2. Remember if the scale factor is less than one the figure reduces. Our rule for dilations is (x,y) → (kx,ky). The scale factor is represented by K. Since your scale factor is 1/2 we know our triangle will reduce. Let's plug 1/2 in our x and y valued.

So E is (8,4). 8*1/2 is 4 and 4* 1/2 is 2. Are new points are E' (4,2).

A 381 foot cable runs from the top of a radio tower to a skate in the ground. If it hits the ground 167 feet from the base of the tower , what is the angle of elevation that is makes with the ground?

Answers

Answer:

64°

Step-by-step explanation:

Using Pythagoras rule :

Cosθ = adjacent / hypotenus

Adjacent = 167

Hypotenus = 381

Cosθ = 167 / 381

Cosθ = 0.4383202

θ = Cos^-1(0.4383202)

= 64.003

Hence, angle of elevation = 64°

Responder:

Si el factor de escala de una figura es mayor que uno, la figura es mayor.

Explicación paso a paso:

Hará que la figura sea más grande porque si es menor que uno, la figura será menor. Por ejemplo, si el factor de escala es la mitad de la cifra, será la mitad más pequeña que la cifra original. Y si el factor de escala es 2, la figura será dos veces más grande que la figura original.

Answers

Answer:

120°

Step-by-step explanation:

If the line were to continue down to form a triangle at the bottom, it would cross the line with an interior angle of 70°. Since we have two of the angles, we subtract them from 180°.

180-70-50=60°

That would be the third interior angle at the top of the triangle. Angle x is supplementary to that.

180-60=120°

8th bounce? Round your answer to the nearest
tenth of a meter.

Answers

Ball will bounce 83.9 meters high on the 8th bounce.

Geometric sequence:

nth term of a geometric sequence is given by the expression,

[tex]T_n=ar^{n-1}[/tex]

Here, [tex]a=[/tex] First term

[tex]r=[/tex] Common ratio in each term

[tex]n=[/tex] Number of term

From the table attached,

First term [tex]a=400[/tex] meters Common ratio [tex]r=\frac{\text{Second term}}{\text{First term}}[/tex]

[tex]=\frac{320}{400}[/tex]

[tex]=0.8[/tex]

8th term of the sequence will be,

[tex]T_8=400(0.8)^{8-1}[/tex]

[tex]T_8=83.886[/tex]

[tex]\approx 83.9[/tex] meters

What is the value of expression below -8.125 + 7 3/8

Answers

Answer:-6/8, -3/4, -0.75

Step-by-step explanation:

Background info:

0.125=1/8

An you can also use the commutative property to "flip" the equation

Let's rewrite -8.125 as 8 1/8 because we know 1/8=0.125

And let's write it as a improper fraction - 65/8 and let's write 7 3/8 too as 59/8

Now we have to use the distributive property and subtract 65/8 from 59/8 (59/8 - 65/8) and you will get -6/8 or simplified -3/4 or in decimal -0.75

There are GCF of two numbers is three and the LCM is 180. If one of the numbers is 45,what is the other number ?

Answers

Answer:

The other number is 12

Step-by-step explanation:

There are GCF of two numbers is three and the LCM is 180. If one of the numbers is 45,what is the other number ?

Let us represent the other number as x

There are GCF of two numbers is three and the LCM is 180.

Therefore:

45 × x = 3 × 180

45x = 3 × 180

x = 3 × 180/45

x = 12

Therefore, the other number is 12
