Answer:

First option: [tex]13 \sqrt{2} [/tex]

Step-by-step explanation:

[tex]cosθ = \frac{adj}{hyp} [/tex]

[tex]cos45° = \frac{13}{y} [/tex]

Multiply both sides by y:

[tex]y(cos45°) = 13[/tex]

[tex]y ( \frac{ \sqrt{2} }{2} ) = 13[/tex]

[tex]y = 13 \div \frac{ \sqrt{2} }{2} [/tex]

[tex]y = 13 \times \frac{2}{ \sqrt{2} } [/tex]

[tex]y = \frac{26}{ \sqrt{2} } ( \frac{ \sqrt{2} }{ \sqrt{2} } )[/tex]

[tex]y = \frac{26 \sqrt{2} }{2} [/tex]

[tex]y = 13 \sqrt{2} [/tex]

Option A

[tex]{\pink{y = 13 \sqrt{2}}}[/tex]

[tex] \sf{cosθ= \frac{ B}{C} }[/tex]

[tex] \dashrightarrow \sf \: {cos45° = \frac{13}{y} }[/tex]

Multiply both sides by y:

[tex] \sf \ \: y(cos45°) = 13y(cos45°)=13[/tex]

[tex] \sf \: y ( \frac{ \sqrt{2} }{2} ) = 13[/tex]

[tex]\implies \sf \: y = 13 \div \frac{ \sqrt{2} }{2}[/tex]

[tex] \sf \implies \: y = 13 \times \frac{2}{ \sqrt{2} }[/tex]

[tex] \implies \sf \: y = \frac{26}{ \sqrt{2} } ( \frac{ \sqrt{2} }{ \sqrt{2} } )[/tex]

[tex] \implies \sf y = \frac{26 \sqrt{2} }{2}[/tex]

[tex] \sf \boxed {\pink{y = 13 \sqrt{2}}}[/tex]

Answer:

x= 17

Step-by-step explanation:

Assuming that the total degree of this side is also 90, we'll subtract 90 with 39.

90 - 39= 51

since x is 3 times the total degree, we'll divide 51 by 3, leaving us with 17.

Answer:

(0,1) point C

Step-by-step explanation:

the line segment PQ is divided into 5 parts ( 3parts +2 parts)

Is very important that you keep the direction correct from P to Q

The point C divides the PQ into 3:2 ratio

(0, 1) is the point that divides the line segment directed from P to Q in the ration of 3 : 2.

Vectorially speaking, we determine the the location of the point that divides the line segment in the ratio of [tex]a : b[/tex].

[tex]R(x,y) = P(x,y) + \frac{a}{a+b}\cdot [Q(x,y) - P(x,y)][/tex] (1)

Where:

If we know that [tex]P(x,y) = (-3, -2)[/tex], [tex]Q(x,y) = (2, 3)[/tex], [tex]a = 3[/tex] and [tex]b = 2[/tex], then the location of the resulting point:

[tex]R(x,y) = (-3, -2) + \frac{3}{5}\cdot [(2,3)-(-3,-2)][/tex]

[tex]R(x,y) = (-3,-2) +\frac{3}{5}\cdot (5, 5)[/tex]

[tex]R(x,y) = (-3, -2) + (3,3)[/tex]

[tex]R(x,y) = (0, 1)[/tex]

(0, 1) is the point that divides the line segment directed from P to Q in the ration of 3 : 2.

Answer:

Step-by-step explanation:

f(x) = 5x + 1

Given these two points on the graph of g(x), we must determine the slope, m, of the line.  Going from (-4, 2) to (2, 14), x (the run) increases by 6 and y (the rise) increases by 12, so the slope is m = rise/run = 12/6, or m = 2.  Adapting the slope-intercept form y = mx + b, we find b as follows:

14 = 2(2) + b, or 14 = 4 + b, or b = 10.  Then g(x) is 2x + 10.

Comparing f(x) = 5x + 1, we determine whether each of the four statements is true or false:

A is false; the respective y-intercepts of f and g are 1 and 10.

B is true:  the respective y-intercepts of g and f are 10 and 1.

C is false; neither y-intercept is 7.

D is false.  1

Answer:

Option D

Step-by-step explanation:

Rule for the reflection of a point (x, y) over the x-axis is given by,

(x, y) → (x, -y)

Applying this rule image point of a point (4, -2) will be,

(4, -2) → (4, 2)

Therefore, Option D will be the correct option.

Step-by-step explanation:

you have a 50/100 chance tyo get an obtusse angel

The probability that the second slip will contain an obtuse angle measure, given the first slip contained an acute angle measure is 3/4.

Conditional probability is occurrence of a certain event based on the occurrence of the previous event.

According to the given question the angle measures 30°, 60°, 120°, and 150° are written on slips of paper.

One student chooses a slip, identifies the type of angle, and returns the slip.

Let A = Choosing an obtuse angle in the second time and B = Choosing an acute angle in the first draw.

Now, P(A/B) = Probability of choosing an obtuse angle when the first draw was an acute angle.

P(A) = 1/2 and P(B) = 2/3.

∴ P(A/B) = (1/2)/(2/3) = 1/2×3/2 = 3/4.

Answer:

18 times

Step-by-step explanation:

Half of the possibilities you can roll are correct. so 18 out of 36 times you roll an odd number.

You could also look at it another way. You can expect to roll each number 6 times, so the 3 odd numbers added together is 18 times.

Answer:

a is -9

b is 4

Step-by-step explanation:

we know that a and b are whole numbers.

we know that they are factors of 36.

1 * 36

2 * 18

3 * 12

4 * 9

6 * 6

i just did this as guess and check.

what numbers have a difference of 5?

the factors 4 and 9.

so, if a is the negative one, a has to be -9 to get -5 because

-9 + 4 = -5

and

(-9)(4) = 36
