Answer:

C = 18.1°

Step-by-step explanation:

A = 142 m²

a = 24 cm, b = 38 cm

Use the formula A = a*b*sinC/2

142 = 24 * 38 * sinC/2 = 456*sinC

sinC = 0.3114

C = 18.1°

Tell whether (-9,2) is a solution of x+3y≥-2

jok3333 [9.3K]

Step-by-step explanation:

<u>Substitute the point (-9, 2) into the inequality:</u>

$-9+3(2)\geq 2$

<u>Simplify:</u>

$-3\geq -2$ False.

-3 isn't greater than or equal to -2.

(-9, 2) is not a solution of $x+3y\geq -2$

Tina is finding the quotient of. Is she correct? If not, what changes should be made?

Mice21 [21]

For this case, we must find the quotient of

$(15x ^ 3 + 12x ^ 2-9x)$ divided by $3x$ , to verify if Tina was correct.

So:

$\frac {15x ^ 3 + 12x ^ 2-9x} {3x} =\\\frac {15x ^ 3} {3x} + \frac {12x ^ 2} {3x} - \frac {9x} {3x} =\\5x ^ 2 + 4x-3$

So, Tina was wrong, she had to divide by 3x.

The sum of two segments are 75 cm, and one the segments are four times the other. Calculate the measurement of each segment

iVinArrow [24]

The length of one segment is 15 cm and other segment is 60 cm

Step-by-step explanation:

Let x be the length of one segment and y be the length of other segment

Then according to given statement

x+y=75 Eqn 1

And

one the segments are four times the other

x=4y Eqn 2

$Putting\ x=4y\ in\ equation\ 1$

$4y+y=75\\5y=75\\Dividing\ both\ sides\ by\ 5\\\frac{5y}{5}=\frac{75}{5}\\y=15\\Putting\ y=15\ in\ eqn\ 2\\x=4(15)\\x=60$

Hence,

The length of one segment is 15 cm and other segment is 60 cm
