If sin theta = 4/5 and theta is in quadrant 2, the value of cot theta is
trasher [3.6K]

Answer:

Cot(theta) = - 0.75 or -3/4

Step-by-step explanation:

The hypotenuse is 5

The y value is 4

We need to find the corresponding x value.

x^2 + y^2 = z^2

X = ?

y = 4

z = 5

x^2 + 4^2 = 5^2

x^2 + 16 = 25

x^2 = 9

Now in this case, you are in quadrant 2, so the x value is - 3

sqrt(x^2) = sqrt(9)

x = - 3

The cot value is the adjacent (x value) / the opposite ( y ) value

Cot(theta) = -3/4

cot(theta) = -0.75

A website received 2500 registered members in July. And the number of registered members in August decreased to 2245. What was t
quester [9]

Number of registrations a website received during July = 2500

Number of registrations a website received during August = 2245

Number by which the registrations decreased :

=\tt 2500 - 2245

=\tt 255

Thus, the registrations decreased by 255.

Let x be the perrcentage of decrease.

Which means :

=\tt 255 =  \frac{x}{100}  \: of \: 2500

= \tt255 =  \frac{x \times 2500}{100}

=\tt 255 =  \frac{2500x}{100}

= \tt255 \times 100  = 2500x

= \tt25500 = 2500x

=\tt  \frac{25000}{2500}  = x

\color{plum} =\tt  \bold{10.2\%}

▪︎Thus, the percentage of decrease in the number of registered members = 10.2%

What is the surface area of the figure shown? Plz answer asap
Luba_88 [7]

Answer:

264\ cm^{2}

Step-by-step explanation:

we know that

The surface area of the figure is equal to the lateral face of the triangular pyramid plus the lateral face of the rectangular prism plus the area of the base of the rectangular prism

step 1

Find the lateral face of the triangular prism

The lateral area is equal to the area of its four lateral triangular faces

LA=4(\frac{1}{2}(6)(7))=84\ cm^{2}

step 2

Find the lateral area of the rectangular prism

The lateral area is equal to the perimeter of the base multiplied by the height

LA=(4)(6)(6)=144\ cm^{2}

step 3

Find the area of the base of the rectangular prism

B=(6)(6)=36\ cm^{2}

step 4

Find the surface area

84\ cm^{2}+144\ cm^{2}+36\ cm^{2}=264\ cm^{2}
