Answer:

x = \sqrt{26}

Step-by-step explanation:

using pythagoras theorem

here \sqrt{13} and \sqrt{13} are the legs of the right angled triangle and x is hypotenuse.

a^2 + b^2 = c^2

(\sqrt{ 13 })^2 + (\sqrt{13})^2 = x^2

13 + 13 = x^2

26 = x^2

\sqrt{26} = x

Can someone please answer this for me
MaRussiya [10]

Answer:

BC = 1.7

Step-by-step explanation:

Since, cosine of any angle (except right angle) represents the ratio of base length and hypotenuse.

Cosθ = \frac{\text{Base}}{\text{Hypotenuse}}

From the given right triangle ΔACB,

\text{Cos}(\angle B) = \frac{\text{Base}}{\text{Hypotenuse}}

              =\frac{BC}{AB}

Cos(70°) =\frac{BC}{5}

BC = 5Cos(70°)

     = 1.71

     ≈ 1.7

A track star in Arizona ran the 100 meter dash event is six track meets. Her average time for all six meets was 11.8 seconds. Sh
natima [27]

Answer:

A track star in Arizona running time in the last meet was 11.5 seconds.

Step-by-step explanation:

Given:

average time for all six meets = 11.8 seconds.

Time for 1st meet = 11.7 seconds.

Time for 2nd meet = 11.6 seconds.

Time for 3rd meet = 12 seconds.

Time for 4th meet = 12.1 seconds.

Time for 5th meet = 11.9 seconds.

We need to find the running time for her last meet.

Solution:

Let the running time for her last meet be 'x'.

So we can say that;

average time for all six meets is equal to sum of Time for 1st meet, Time for 2nd meet, Time for 3rd meet,Time for 4th meet, Time for 5th meet and time for her last meet and then divided by 6.

framing in equation form we get;

\frac{11.7+11.6+12+12.1+11.9+x}{6}=11.8\\\\\frac{59.3+x}6 =11.8

Now Multiplying both side by 6 we get;

\frac{59.3+x}{6}\times 6= 11.8\times6\\\\59.3+x=70.8

Now Subtracting both side by 59.3 we get;

59.3+x-59.3=70.8-59.3\\\\x=11.5 \ s

Hence A track star in Arizona running time in the last meet was 11.5 seconds.

Pls pls help! 50pts!!!
Alchen [17]

Answer:

I figured all these out by graphing the function. See the attachment for a picture.

h(x) = (x-1)^2

It's <u>increasing over (1, ∞)</u> because the values are going up in that span.

It's <u>decreasing over (-∞, 1)</u> because the values are going down in that span.

Its range is all values of <u>y </u>\geq<u> 0</u> (we can see that only y-values above 0 are in the function).

g(x) = -(x+1)(x-1)

It's <u>increasing over (-∞, 0)</u> because the values are going up in that span.

It's <u>decreasing over (0, ∞)</u> because the values are going down in that span.

Its range is all values of <u>y </u>\leq<u> -1</u> (we can see that only y-values below 1 are in the function).
