what is the value of (-1/2) to the -4 power

Answer:

1) [tex]x=15, y=41[/tex]

2) [tex]x=6, y=24[/tex]

Step-by-step explanation:

1)

The two triangles are similar by AA similarity.

That means [tex]5x-5=4x+10[/tex].

We can add [tex]5[/tex] to both sides to get [tex]5x=4x+15[/tex].

We can then subtract [tex]4x[/tex] from both sides to get [tex]x=15[/tex].

We know that the [tex](5x-5)+(6y-4)=180[/tex]  because they both lie on a straight line.

We can plug in for [tex]x[/tex] to get [tex](5(15)-5)+(6y-4)=75-5+6y-4=6y-66=180[/tex].

We can divide both sides of the equation by [tex]6[/tex] to get [tex]y-11=30[/tex].

We then add [tex]11[/tex] to both sides to get [tex]y=41[/tex].

So, [tex]\boxed{x=15, y=41}[/tex] and we're done!

2)

Because the two bases of a trapezoid are parallel, meaning adjacent top and bottom angles sum to [tex]180^{\circ}[/tex], we have that [tex]90+3y+18=180[/tex].

We can subtract a [tex]90[/tex] and an [tex]18[/tex] from both sides to get [tex]3y=72[/tex].

We then divide both sides of the equation by [tex]3[/tex] to get [tex]y=24[/tex].

We do the same thing for [tex]x[/tex]. On the other side of the trapezoid, we have that [tex]15x+30+10x=180[/tex].

We combine like terms on the left side to get [tex]25x+30=180[/tex].

We subtract a [tex]30[/tex] from both sides to get [tex]25x=150[/tex].

We divide both sides of the equation to get [tex]x=6[/tex].

So, [tex]\boxed{x=6, y=24}[/tex] and we're done!

Answer:

70000

Step-by-step explanation:

Answer:

£14708.75

Step-by-step explanation:

Always start with the original amount, in this case 14000.

Then, because it's an increase, add 2.5 to 100. You could also think of it as adding 2.5% to 100%, which is 102.5%. We then divide that by 100.

So far our calculation is 14000 x 1.025.

We now need to do this for the two days on. We can do this in 2 ways.

1. 14000 x 1.025 x 1.025

or.

2. 14000 x 1.025^2

They're both the same thing.

We then type that calculation into your calculator and you should get £14708.75

Hope that helped :)

Step-by-step explanation:

I can't draw here, but I can describe :

an isoceles triangle means that 2 sides of the triangle are equally long (they are typically called the "legs" left and right on top of the baseline).

this fact makes the triangle symmetrical.

and that means that 2 angles are also equal (the angles of the legs with the baseline).

so, knowing that one angle is 34 degrees can mean 2 things :

either 34 degrees is the angle between the 2 legs, or it is one of the 2 equal angles between legs and baseline.

as we know the sum of all angles in a triangle is always 180 degrees.

so case 1 : 34 degrees is the angle between the legs

180 = 34 + 2×base-leg-angle

144 = 2×base-leg-angle

each base-leg-angle = 72 degrees

case 2 : 34 degrees is one of the base-leg-angles

180 = 2×34 + between-the-legs-angle

180 = 68 + between-the-legs-angle

between-the-legs-angle = 112 degrees

so, you need to draw one triangle for each case.

since we don't know anything about the side lengths, size does not matter. only the angles need to be correct :

one triangle with 34, 72, 72 degrees

and one triangular with 34, 34, 112 degrees

Answer:

-9.6

Step-by-step explanation:

The product of the given expression [−12 ⋅ 4/7]⋅[−14⋅(−0.1)] is approximately -9.6.

We have,

Let's break down the expression step by step:

[−12 ⋅ 4/7]⋅[−14⋅(−0.1)]

First, let's simplify the expressions inside each set of brackets:

-12 ⋅ 4/7 = -48/7

-14 ⋅ (-0.1) = 1.4

Now, substitute these values back into the original expression:

[-48/7]⋅[1.4]

Now, multiply the two fractions:

(-48/7) * 1.4 = -67.2 / 7

This can be simplified further by dividing both the numerator and the denominator by their greatest common divisor, which is 1:

-67.2 / 7 ≈ -9.6

Thus,

The product of the given expression is approximately -9.6.

Answer:

true is the answer

Step-by-step explanation:

hope it helps.

Answer:

4.) Cost of cordless phone = $55

cost of each additional handset = $25  

Therefore, the overall cost of the cordless phone, including the 3 extra handsets is:

$55 + 3($25) = $55 + $75 = $130

5.) Given the function, f(d ) = .20d + 14, where:

f(d) = global temperature (in Celsius)

d = number of decades  

To evaluate the value of f (d ) at f(10), you'll have to substitute the value of d = 10 as input into the function:

f(10) = .20(10) + 14

f(10) = 2 + 14

f(10) = 16

6.) Value of f(10):

    In 10 decades, the predicted global temperature will be 16° Celsius.

7.) The correct answer is B. The global temperature f(d) depends on the number of decades, d.

Explanation: the independent variable is d →  it is the input of the function. The output primarily depends on the given value of input.

8.) Given the function, f(t ) = 0.2t

where t = represents number of days elapsed since the planting of the seed.

         Evaluate f(40):

        f(40) = 0.2(40)

        f(40) = 8
