The equation which is used to find the value of c will be c = 5/Cos 35

The branch of mathematics sets up a relationship between the sides and the angles of the right-angle triangle is termed trigonometry.

We are given the following

m<ACB = 90degrees

m<ABC = 35degrees

The side opposite to m<ABC is AC

BA = hypotenuse

CB = adjacent = 5inches

Required

The equation to solve BA which is c

Using the Pythagoras theorem;

Cos Ф = Adjacent/Hypotenuse

Cos m<ABC = CB/BA

Cos m<ABC = 5/c

c = 5/cosm<ABC

c = 5/Cos 35

Hence the equation that can be used to solve for c is c = 5/Cos 35

Based on this construction, the value of m∠ABC is 64°.

From the point, E and D, two arcs are made which are intersecting each other at point P.

It means, that line BP is the bisector of angle ABC. ABC will be:

= 2 * 32=64

Answer:

2) d. 60°

3) a. AB

Step-by-step explanation:

Question 2

ΔABC and ΔCDA are congruent because:

This means the corresponding side lengths and angles are equal.

Therefore,

∠CDA = ∠ABC

⇒ x = 60°

Question 3

The hypotenuse is the longest side of a right triangle - the side opposite the right angle (the right angle is shown as a small square).

Therefore, the hypotenuse of ΔABC is the line AB.

Answer:

c.

Step-by-step explanation:

we estimate by rounding the factors to "easy numbers". that means numbers we can easily calculate even in our heads, and we get at just a ballpark number as result for orientation.

59 is much closer to 60 than to 50.

42 is much closer to 40 than to 50.

of course, we round to the closest "round numbers", so that the loss of precision through the rounding is as little as possible, so that the estimation still gives a much value as possible.

and the sum of the differences of the factors should be as close to 0 as possible.

so, 60×40 is the closest and therefore best estimation.

the sum of the factor differences is (+1 - 2) = -1.

compare to the real result :

59×42 = 2,478

answer a and b are by the way not correct :

50×40 = 2000 (and not 2500)

60×50 = 3000 (and not 3500)

FYI - in this case 50×50 = 2500 would be the closest estimation.

and the sum of the factor differences would be (-9 + 8) = -1.

normally, this wide "jumping" (-9 to +8) would make it only second choice.

Perpendicular lines are lines that intersect at a 90 degrees angle. Parallel lines are lines that are always the same distance apart.

draw the graph then use the graph to answer the following questions

Answer:

y=x^(2)+10x+11,y=x^(2)+x-7

Step-by-step explanation:

I think so bro

Step-by-step explanation:

I assume you mean

y = x² + 10x + 11

y = x² + x - 7

well, I subtract equation 2 from equation 1 :

0 = 9x + 18

9x = -18

x = -2

y = x² + x - 7 = (-2)² - 2 - 7 = 4 - 2 - 7 = -5

the solution (the intersection point of both graphs) is the point (-2, -5).

Mitra used 156 white tiles of 2x2 cm and 76 black tiles of 2x3 cm to form a pattern with an area of 1092 cm²

An equation is an expression that shows the relationship between two or more numbers and variables.

Let x represent the number of white tiles and y represent the number of black tiles.

Area of white tiles = 2 cm * 2 cm = 4 cm²

Area of black tiles = 2 cm * 3 cm = 6 cm²

She used twice as many white tiles as black tiles. Hence:

x = 2y   (1)

Also, the finished pattern was 1092 square centimeters in area. Hence:

4x + 6y = 1092   (2)

From both equations:

x = 156, y = 78

Reason:

There are 4 outcomes we don't want (rolling 1,2,3 or 4) and 2 outcomes we do want (rolling 5 or 6)

This gives the odds against ratio of 4:2 or 2:1

This can be written out as "2 to 1" or "two to one".

Having 2 to 1 odds means that we're twice as likely to get something we don't want vs something we do want.

Answer: [tex]\frac{4}{15}[/tex] of the pizza was left

Step-by-step explanation:

lets first get the denominators the same..

[tex]\frac{1}{3} = \frac{5}{15}[/tex]

[tex]\frac{2}{5} = \frac{6}{15}[/tex]

To find the total pizza eaten we add these two fractions

[tex]\frac{5}{15} +\frac{6}{15} =\frac{11}{15}[/tex]

we can think of [tex]\frac{15}{15}[/tex] as 1 pizza because it simplifies to 1

[tex]\frac{15}{15} -\frac{11}{15} =\frac{4}{15}[/tex]

Therefore, [tex]\frac{4}{15}[/tex] of the pizza was left

Step-by-step explanation:

The volume of a cone is [tex]\frac{1}{3} \pi r^{2}h[/tex]. The radius is 4 and the height is 8, so these values can be plugged in:

[tex]V = \frac{1}{3} \pi \times 4^{2} \times 8[/tex]

[tex]V = \frac{128\pi }{3}[/tex]

This is about 134.041286553 which rounds to 135 ft^3.

Answer:

-7/2 or 2 are inputs that give 19 as output.

Step-by-step explanation:

The problem gives us a quadratic function [tex]\displaystyle \large{f(x)=2x^2+3x+5}[/tex]. When its output is 19, we want to know the input value(s).

Since an output which is f(x) = 19. Therefore:

[tex]\displaystyle \large{19=2x^2+3x+5}[/tex]

Rearrange the expression in quadratic equation.

[tex]\displaystyle \large{0=2x^2+3x+5-19}\\\\\displaystyle \large{0=2x^2+3x-14}\\\\\displaystyle \large{2x^2+3x-14=0}[/tex]

Factor the expression.

[tex]\displaystyle \large{(2x+7)(x-2)=0}[/tex]

Solve like linear equation which we get:

[tex]\displaystyle \large{x=-\dfrac{7}{2}, 2}[/tex]

If you input these x-values in the function, you will get 19 as the output which satisfies the condition.

Hence, inputs are -7/2, 2

Answer:

[tex]x=2, \quad x=-\dfrac{7}{2}[/tex]

Step-by-step explanation:

Set the function to 19:

[tex]\implies 2x^2+3x+5=19[/tex]

Subtract 19 from both sides:

[tex]\implies 2x^2+3x-14=0[/tex]

To factor a quadratic in the form [tex]ax^2+bx+c[/tex]

Find two numbers that multiply to [tex]ac[/tex] and sum to [tex]b[/tex]:  7 and -4

Rewrite [tex]b[/tex] as the sum of these two numbers:

[tex]\implies 2x^2-4x+7x-14=0[/tex]

Factorize the first two terms and the last two terms separately:

[tex]\implies 2x(x-2)+7(x-2)=0[/tex]

Factor out the common term (x - 2):

[tex]\implies (2x+7)(x-2)=0[/tex]

Therefore the function's input values that when evaluated give a value of 19 are:

[tex](2x+7)=0 \implies x=-\dfrac{7}{2}[/tex]

[tex](x-2)=0 \implies x=2[/tex]

Suppose there is this little town with a finite number of people: (1) No two inhabitants have exactly the same number of hairs. (2) No inhabitant has exactly 743 hairs or no hairs at all. (3) There are more inhabitants than there are hairs on the head of any inhabitant.

Let say there are 519 people in the town. and make them stand in a line with increasing number of hairs on their heads. This way, there will be a person on the last, who has no hair.

There are more number of people than the hairs. From bald to 742 hairs, 743 is the limit.
