Answer please i need help with this

stellarik [79]

$\qquad\qquad\huge\underline{\boxed{\sf Answer}}$

Let's evaluate ~

$\qquad \sf \dashrightarrow \: \dfrac{1}{3 {}^{ - 2} \times {x}^{ - 4} \times {y}^{2} }$

plug in the values :

$\qquad \sf \dashrightarrow \: \dfrac{1}{3 {}^{ - 2} \times {3}^{ - 4} \times { - 1}^{2} }$

$\qquad \sf \dashrightarrow \: \dfrac{1}{3 {}^{ - 6} {}^{ } {}^{} }$

$\qquad \sf \dashrightarrow \: {3}^{6}$

$\qquad \sf \dashrightarrow \:729$

Therefore, B is the Correct choice ~

- Write the equation for tan 32.

Marizza181 [45]

Answer:

If the angle is 32, then the tan of 32 degrees will be 0.625.

Step-by-step explanation:

This is useful because if you know either Opposite or Adjacent length, you can enter it in the equation above and solve for the missing length.

You can also re-write the equation above to solve for Opposite and Adjacent to get the following new equations:

Opposite = 0.625 x Adjacent

Adjacent = Opposite / 0.625

What is the area of this composite shape? Enter your answer in the box. _in²

LuckyWell [14K]

The area of the composite figure is $40 in^2$

Explanation:

From the given figure, we can see that the area of the composite figure = area of the rectangle + area of the triangle.

Area of the rectangle $(A_1)$ :

The formula is given by

$A_1=length\times width$

where $length = 5$ and $width = 5$

Substituting, we have,

$A_1=7\times 5=35 in^{2}$

Thus, the area of the rectangle = $35 i n^{2}$

Area of the triangle $(A_2)$ :

The formula is given by

$A_2=\frac{1}{2} bh$

where $b=5-3=2 i n$

and $h=12-7=5 \text { in }$

Substituting, we have,

$A_2=\frac{1}{2} (2)(5)\\A_2=5 in ^{2}$

Thus, the area of the triangle = $5in ^{2}$

Area of the composite figure = Area of the rectangle + area of the triangle

Area of the composite figure = $35 i n^{2}+5 i n^{2}=40 i n^{2}$

Thus, the area of the composite figure is $40 in^2$

Answer:

y=3/4x+-3

Step-by-step explanation:

first use rise over run to find the slope. go up 3 and over four making the slope 3/4. nxet locate the y-intercept which is clearly at -3. now just substitute the values into the equation y=mx+b
