Solve the triangle. A=44 degrees, a = 7,b=8

Answer:

If this is right then yw :)

Step-by-step explanation:

"Hope this is your question, if not I think you will, still be able to find an answer of your question based on this solution"

The expression is :

2(z-4)

so we may think that the given value is z = 12.8 instead of x=12.8, then only we can plug it in given expression.

so plugging z=12.8 in the expression:

2(12.8-4)

We will use PEMDAS rule here,

So simplifying parenthesis first,

12.8-4 = 8.8

Now multiplying the result 8.8 with 2 to get the answer,

8.8 *2 = 17.6

Answer : 2(z-4) = 17.6 for z=12.8

Step-by-step explanation:

The measure of line segment EG is 13 cm.

Given that, F is between E and G, EF=7 and FG=6.

We need to find the measure of EG.

A line segment is a part of a line that has two endpoints and a fixed length. It is different from a line that does not have a beginning or an end and which can be extended in both directions. In this lesson, we will learn more about a line segment, its symbol, and the way to measure a line segment.

Now, EG=EF+FG

⇒EG=7+6=13 cm

Therefore, the measure of line segment EG is 13 cm.

Answer:

Option D is correct

[tex]y = 9.50x[/tex]

Step-by-step explanation:

Here, y represents total earnings in dollars and  x represents hours worked.

As per the statement:

To find which equation models the wages of someone who makes $9.50 an hour.

[tex]\text{"\$9.50 an hour"}[/tex] translated to 9.50x

then;

the total earning in dollars we get;

[tex]y = 9.50x[/tex]

Therefore, an equation [tex]y = 9.50x[/tex] models the wages of someone who makes $9.50 an hour

The general equation in slope intercept form is given by:

[tex] y=mx+b [/tex]

where m is the slope and b is the y intercept.

Now we are given slope as 3 and y intercept as 4, plugging these values in the slope intercept form, we get

[tex] y=3x+4 [/tex]

Now if we compare the two equations, we see that option (b) y=3x+4 matches our requirement.

So answer is the equation with slope 3 and y intercept 4 is y=3x+4.

Riya is applying mulch at a rate of 0.025 m^3/m^2 after converting the original rate of 25,000 cm^3/m^2 to cubic meters per square meters.

To find out the rate at which Riya is applying mulch in m^3/m^2, you first need to convert the given value from cubic centimeters (cm^3) to cubic meters (m^3). We know that 1 m = 100 cm, so 1 m^3 = 100 cm * 100 cm * 100 cm = 1,000,000 cm^3. Therefore, we need to divide the given value by 1,000,000 to convert it from cm^3 to m^3. So, if Riya applies 25,000 cm^3 of mulch for every m^2 of garden space, this is equivalent to 25,000/1,000,000 = 0.025 m^3/m^2.

In conclusion, Riya is applying mulch at a rate of 0.025 m^3/m^2.

The least common multiple of x² + x – 12 and x² + 2x – 15 is (x + 4)(x – 3)(x + 5), Option A is correct.

A quadratic equation is a second-order polynomial equation in a single variable x , ax2+bx+c=0. with a ≠ 0 .

We need to find the least common multiple of x² + x – 12 and x² + 2x – 15.

Let us find the factor of x² + x – 12

x² + 4x -3x – 12

x(x+4)+3(x+4)

(x + 4)(x – 3)

Now let us factorize x² + 2x – 15.

x² + 5x-3x – 15.

x(x+5)-3(x+5)

(x-3)(x+5)

So, the least common multiple of x² + x – 12 and x² + 2x – 15 is (x + 4)(x – 3)(x + 5).

Hence, the least common multiple of x² + x – 12 and x² + 2x – 15 is (x + 4)(x – 3)(x + 5), Option A is correct.

Final answer:

To estimate the total cost, round each item to the nearest $0.10, sum them up, and subtract from the amount given by the customer. The estimated total cost is $9.80, and the estimated change to be returned is $1.45.

Explanation:

To estimate the total amount the customer owes after rounding to the nearest $0.10, we need to perform the following calculations:

Apple pie: $8.04, rounded to $8.00

6 cloves of garlic: $0.09 each, so $0.09 x 6 = $0.54, rounded to $0.50

Quart of milk: $1.31, rounded to $1.30

The estimated total cost is $8.00 (apple pie) + $0.50 (garlic) + $1.30 (milk) = $9.80.

The customer gives a total of $5 + $6 + $0.25 = $11.25.

Subtracting the estimated total cost from the amount given by the customer:
$11.25 - $9.80 = $1.45, which is the estimated change to be returned to the customer.

Answer:

a , b, c are only applicable in graph.

Step-by-step explanation:

Given : The function  [tex]f(x)=3sin(\frac{x}{4}+1)-\frac{1}{2}[/tex]

To find : Which of the following are correctly represented in the graph?

Solution :

General form of sin function is [tex]y=A sin(B(x-C)+D[/tex]

Where A is the amplitude

[tex]B=\frac{2\pi}{\text{Period}}[/tex]

D is the vertical shift.    

C is the horizontal shift or phase shift.

Comparing with the general form:      

[tex]f(x)=3sin(\frac{x}{4}+1)-\frac{1}{2}[/tex]

Transform little bit we get,

[tex]f(x)=3sin(\frac{1}{4}(x-(-4)))-\frac{1}{2}[/tex]

a. Amplitude is [tex]A=3[/tex]

It is correct.

b. Vertical shift is [tex]D= -\frac{1}{2}[/tex]

it is correct.

c. Horizontal shift [tex]C=-4[/tex]

It is correct.

d. Period is [tex]P=\frac{2\pi}{B}[/tex]

[tex]P=\frac{2\pi}{\frac{1}{4}}[/tex]    

[tex]P=8\pi[/tex]    

It is not correct .

Actual period in graph is [tex]2\pi[/tex]

e. The horizontal expansion or compression

It also not correct because period is not correct.

The expansion and compression depends on the period.

Therefore, a , b, c are only applicable in the graph.

Answer:

0.989

Step-by-step explanation:

A conservationist determines that a particular beach is eroding at a rate of 1.1% each year. When writing an explicit formula to represent the amount of beach remaining each year, the common ratio is 0.989

The required explicit formula to represent the amount of beach remaining each year will be y = a(0.011)^x

Exponential functions are inverse of trigonometry functions. The standard form of exponential function is expressed as:

y = ab^x

b is the rate

Given;

Rate = 1.1% = 0.011

The required explicit formula to represent the amount of beach remaining each year will be y = a(0.011)^x
