B and D is wrong, as the x-axis (years), can best be represented in increments of 1. This leaves A and C. Of them, A is the best as you can fit all of the data in there without any issues.

Find the measure of angles 1, 2, 3, 4, 5 ,6 and 7

vivado [14]

Answer:

angle1=70

angle2=65

angle4=115

angle7=45

angel6=45

angle5=45

Step-by-step explanation:

110+angle1 = 180

angle1 =180-70

angle1 = 70

115+angle2=180

angle2=180-115

angle2=65

angle4=115 because lines are parallel

angle1+angle2+angle7=180 because triangle

70+65+angle7=180

135+angle7=180

angle7=180-135

angle7=45

angel6=45

angle5=45

$\sf y=50\left(1.8\right)^{x}$

=================================

the first term : 50

crosses point : (0, 50), (1, 90)

solve for y,

$\sf y=50\left(1.8\right)^{1}$

$\sf y=90$

<h3>Thus D is correct option.</h3>

Which polynomial correctly combines the like terms and expresses the given polynomial in standard form?

Lera25 [3.4K]

Answer:

The first option

Step-by-step explaination:

$9 {xy}^{3} - 4 {y}^{4} - 10 {x}^{2} {y}^{2} + {x}^{3} y + {3x}^{4} + {2x}^{2} {y}^{2} - 9 {y}^{4}$

$(- 4 {y}^{4} - 9 {y}^{4} ) + ( - 10 {x}^{2} {y}^{2} + {2x}^{2} {y}^{2}) + 9 {xy}^{3}+ {x}^{3} y + {3x}^{4}$

$- 13 {y}^{4} - 8 {x}^{2} {y}^{2} + 9 {xy}^{3} + x {}^{3} y + 3x {}^{4}$

$- 13 {y}^{4} + {3x}^{4} - 8 {x}^{2} {y}^{2} + {x}^{3} y + {9xy}^{3}$

If BC= 48 cm and sin

erastovalidia [21]

Using relations in a right triangle, it is found that the length of AC is of 14 cm.

<h3>What are the relations in a right triangle?</h3>

The relations in a right triangle are given as follows:

The sine of an angle is given by the length of the opposite side to the angle divided by the length of the hypotenuse.

The cosine of an angle is given by the length of the adjacent side to the angle divided by the length of the hypotenuse.

The tangent of an angle is given by the length of the opposite side to the angle divided by the length of the adjacent side to the angle.

Researching this problem on the internet, we have that:

The opposite leg to angle A is of 48 cm.

sin(A) = 0.96.

Hence the hypotenuse is found as follows:

sin(A) = 48/h

0.96 = 48/h

h = 48/0.96

h = 50 cm.

The length of side AC is the other leg of the triangle, found using the Pythagorean Theorem, hence:

$x^2 + 48^2 = 50^2$

$x^2 = \sqrt{50^2 - 48^2}$

x = 14 cm.
