help me please !!!!!!!!!!!

Answer:

BD = c sin A and BD = a sin C.

Therefore, a sin C = c sin A.  

Divide both sides by sin A × sin C to get A/sin A = C/sin C

Answer:

28° A

Step-by-step explanation:

we have isosceles triangle, which's 2 sides and 2 angles are equal.

we have two equal sides, so another side is base.

base angles are equal, so if E=28 thenG=28 too

Answer:

28 degrees, it A

Step-by-step explanation:

The required simplified value of the given expression is ln[3x³]. Option A is correct.

The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.

here,
Given expression,
= 4 lnx + ln 3 - ln x
= ln x⁴ + ln [3 / x]   [since ln a - ln b = ln [a / b]]
= ln [3x⁴/x]     [since lna + ln b = ln ab]
= ln[3x³]

Thus, the required simplified value of the given expression is ln[3x³]. Option A is correct.

Answer:

After 10 weeks, Tara will have taken 50 quizzes.

Step-by-step explanation:

Given that Tara took a total of 45 quizzes during the 9-week course, to determine the number of quizzes she will take after 10 weeks, taking into account that it is a proportional relationship, the following calculation must be performed:

(45/9) x 10 = X

5 x 10 = X

50 = X

So, after 10 weeks, Tara will have taken 50 quizzes.

Answer:

PZ = 15

Step-by-step explanation:

Similar Triangles

Two triangles are similar if all of their corresponding side lengths are proportional to the same scale factor.

It's given triangles TPR and XPZ are similar, thus we can find the scale factor by comparing two corresponding sides with known lengths.

Sides TR and ZX are corresponding and the proportion of their side lengths is 15/9. The same proportion must be satisfied by the sides TP and XP:

[tex]\displaystyle \frac{15}{9}=\frac{25}{PX}[/tex]

PX and PZ are congruent, thus:

[tex]\displaystyle \frac{15}{9}=\frac{25}{PZ}[/tex]

[tex]\displaystyle PZ=25*\frac{9}{15}[/tex]

Calculating:

PZ = 15

Answer:

The value of y  = 30 when x = 5

Step-by-step explanation:

We know that when 'y' varies directly proportional to 'x', we get the equation

y ∝ x

y = kx

k = y/x

where k is called the 'constant of direct variation'.

We are given

y = 12 when x = 2

so substituting y = 12 and x = 2 in the equation

k = y/x

k = 12/2

k = 6

Thus, the value of k = 6

We have to determine the value of y when x = 5

so substitute x = 5 and k = 6 in the equation

y = kx

y = 6(5)

y = 30

Therefore, the value of y  = 30 when x = 5

Answer:

2/10, 3/15, and 4/20 as well as 0.2

Step-by-step explanation:

Answer:

Step-by-step explanation:

Use a distributive property.

Isolate the term of y from one side of the equation.

[tex]\Longrightarrow: \sf{A(B+C)=AB+AC}[/tex]

⇒: 4(y+2)=32

First, divide by 4 from both sides.

[tex]\Longrightarrow:\sf{\dfrac{4(y+2)}{4}=\dfrac{32}{4} }[/tex]

Solve.

⇒ 32/4=8

⇒ y+2=8

Subtract by 2 from both sides.

[tex]\Longrightarrow \sf{y+2-2=8-2}[/tex]

Solve.

Subtract the numbers from left to right.

8-2=6

y=6
