Rose made 56 phone calls in 3 months. In the first month she made 24 calls, and in the second month she made 13 calls. How many calls did she make in the third month?

Answer:

First, if we have a function defined as:

[tex]G(x) = \int\limits^x_0 {f(t)} \, dt[/tex]

then:

G'(x) = f(x)

[tex]F(x) = \int\limits^x_0 {cos(t)^2} \, dt[/tex]

then:

F' = dF/dt = cos(t)^2

F'(1) = cos(1)^2 = 0.2919

If we round it up to the third digit after the decimal point we get:

F'(1) = 0.292

The correct option is the second one.

Answer:

the stated ratio means that of the 180 degrees involving two supplementary angles, the smaller angle is one sixth of that whole. Thus the smaller angle measures 30 degrees & the larger measures 150 degrees.

Answer:

-1333/1000

Step-by-step explanation:

Evaluate tan(sin^-1(-4/5)).

First we need to evaluate the expression in parenthesis

sin^-1(-4/5)

= sin^-1(-0.8)

= -53.13

SUbstitute the given value into the original expression as shown;

tan(sin^-1(-4/5))

=  tan(-53.13)

= -1.333

= -1333/1000

Hence the required answer is  -1333/1000

Answer:

A

Step-by-step explanation:

m angle b equals 59 now we have to find the arc of angle b.

so use the equation arc AC = 2(59)

arcAC = 118

360 - 118

=242

121/2

= 60.5

x = 17°

Step-by-step explanation:

total angle is 90°

so the equation is

90°=73°+ x

x = 90°-73°

x=17°

step-by-step explanation:

the formula for the volume of a cone is v=πr²h/3

with that let us 'fill in' the formula-

v=π*9.6²*26.5/3

v=2,557.51

then since you've asked us to round the answer to the nearest whole number that would be 2,558

Step-by-step explanation:

This is an overlapping triangles problem.  Try drawing them separately, essentially pulling them apart.  Mark side XY and XZ as congruent (given).

Angle X is shared by the two triangles, so angle X in triangle XAZ is congruent to angle A in triangle XBY.

Step-by-step explanation:

Quadrilaterals are shapes that have a total of four sides. Rectangles, parallelograms, squares, and rhombuses all have a total of four sides. Therefore, they are quadrilaterals.

Rectangle, Parallelogram, Square and Rhombus are Quadrilaterals.

We know,

A quadrilateral is a polygon with four sides. It is a geometric shape that is characterized by having four straight sides and four vertices. The interior angles of a quadrilateral add up to 360 degrees.

As, Rectangle have four sides then it is a quadrilateral.

As, Parallelogram have four sides then it is a quadrilateral.

As, Square have four sides then it is a quadrilateral.

As, Rhombus have four sides then it is a quadrilateral.

Answer:

8 hours

Step-by-step explanation:

We have that;

B = number of bacterial cells, B, in a container after t hours

t = time taken in hours

The function is;

B=25x2t

Where B = 400 bacterial cells

400 = 25x2t

t = 400/25x2

t = 8 hours

Answer:

720 pounds

Step-by-step explanation:

According to the scenario, calculation of the given data are as follows,

Number of mangoes in a barrel = 400

Each mango weight = 1.8 pounds

So, we can calculate the total weight of mangoes by using following formula,

Total weight = Number of mangoes in a barrel × Each mango weight

By putting value, we get

Total weight = 400 × 1.8 pounds

= 720 pounds

Answer:

Length of smaller side = 15 inches

Length of bigger side = 36 inches

Length of hypotenuse = 39 inches

Step-by-step explanation:

Given:

Length of smaller side = a

Length of bigger side = (a + 21) inches

Length of hypotenuse = (a + 24) inches

Find:

Length of all side

Computation:

Using Pythagorean theorem

Hypotenuse² = Base² + Perpendicular²

(a+24)² = a² + (a+21)²

a² + 576 + 48a = a² + a² + 441 + 42a

a² - 6a - 135 = 0

(a-15)(a+7)

So

a = 15 inches a = -7 inches

So,

Length of smaller side = a = 15 inches

Length of bigger side = (a + 21) inches = 15 + 21 = 36 inches

Length of hypotenuse = (a + 24) inches = 15 + 24 = 39 inches
