What is -15.5t + 13.24 = -13.44 + 10.56 – 3.1t

Tatiana [17]

First, subtract 13.24 from both sides of the equation and add -3.1t on both sides of the equation. This isolates the variable t:

-15.5t + 3.1t = -13.44 + 10.56 - 13.24

Now combine the numbers on both sides of the equation and solve for t:

-12.4t = -16. 12
t = 1.3

Hope this helps!

if α,β are the roots of the equation x^{2}-3x+2=0 form an equation whose roots are (α+β)² & (α-β)²

GuDViN [60]

<u>Solution</u><u>:</u><u>-</u>

Let's find roots of x² - 3x + 2

=> x² - 3x + 2 = 0.

=> x² - x - 2x + 2 = 0.

=> x ( x - 1 ) -2 ( x - 1) = 0.

=> ( x - 1 ) ( x - 2 ) = 0.

=> x = 2, 1.

Now

( a + ß )² = (2+1)²=3²=9
( a - ß )² = ( 2 - 1 )² = 1² = 1.

So , equⁿ would be ,

=> x² - ( 9 + 1)x + 9×1=0.

<u>=> x² - 10x + 9=0.</u>

Mr. Gonzazales has only 42.50 to spend he wants to buy 29 t shirts including tax and some bracelets that cost 4.50 each includin

erica [24]

Answer:

He can buy <u>3 bracelets</u>.

Step-by-step explanation:

Given:

Mr. Gonzales has only 42.50 to spend he wants to buy 29 t shirts including tax and some bracelets that cost 4.50 each including tax.

Now, to find the number of bracelets he can buy.

Let the number of bracelets he can buy be $x.$

Price of each bracelets = 4.50.

Total amount to spend = 42.50.

Number of t-shirts = 29.

Now, to get the number of bracelets we put an equation:

$29+4.50\times x=42.50\\\\29+4.50x=42.50$

<em>Subtracting both sides by 29 we get:</em>

<em /> $4.50x=42.50-29\\\\4.50x=13.5$ <em />

<em>Dividing both sides by 4.50 we get:</em>

$x=3.$

<u>The number of bracelets = 3.</u>

Therefore, he can buy 3 bracelets.

A rocket is launched from the ground and travels in a straight path. The angle of inclination of the rocket's path is 1.2 radian

gladu [14]

Answer:

a) $S=2.57$

b) $H=203.2yard$

c) $X=121.79yards$

Step-by-step explanation:

From the question we are told that:

Angle $\theta=1.2=68.755^o$

a)

Generally the equation for Slope is mathematically given by

$S=tan \theta$

$S=tan 68.755$

$S=2.57$

b)

Given the right Angle triangle with horizontal distance $x=85yard$

Generally the equation for Height traveled is mathematically given by

$H=tan\theta*x$

$H=2.57*85$

$H=218.45$

$H=203.2yard$

c)

Generally the equation for Horizontal Distance traveled at 313 height traveled is mathematically given by

$X=\frac{313}{tan65.75}$

$X=\frac{313}{2.57}$

$X=121.79yards$
