Answer:

F(X) = 5 or -6

Step-by-step explanation:

F(X)  = [tex]x^{2} +x-30[/tex]

Using the Formula

[tex]-b[/tex]±[tex]\frac{\sqrt{b^{2} -4ac } }{2a}[/tex]

Where a = coefficient of [tex]x^{2}[/tex] i. e 1

b = coefficient of [tex]x[/tex] i. e 1

And c = 30

imputing the values, we have

[tex]-1[/tex] ± [tex]\frac{\sqrt{1^{2} - 4 X 1 X 30} }{2 X 1}[/tex]

[tex]-1[/tex] ± [tex]\frac{\sqrt{121} }{2}[/tex]

[tex]-1+\frac{11}{2}[/tex] OR [tex]-1-\frac{11}{2}[/tex]

Therefore, F(X) is either 5 or -6

Final answer:

To calculate the charge for a 36-mile drive by Sigi's taxi company, multiply 0.60 by 36 to find the mileage cost, add the $4.50 bridge toll, which results in a total cost of $26.10. Hence, the correct answer is (b) $26.10.

Explanation:

The question asks how much Sigi’s taxi company will charge for a 36-mile drive considering their rate is $0.60 per mile and there is an additional charge of $4.50 for bridge tolls. To calculate the total cost, you can use the given expression 0.60m + 4.50, where 'm' represents the number of miles.

By substituting 36 for 'm', you get the following calculation: 0.60 × 36 + 4.50. The cost per mile for 36 miles amounts to $21.60 ($0.60 times 36). Add the additional $4.50 charge for bridge tolls to get a total charge of $26.10.

Step-by-Step Calculation:

Therefore, the correct option is (b) $26.10.

The value of [tex]\log _{6}(36)[/tex] is 2.

Solution:

Given expression is [tex]\log _{6}(36)[/tex].

To evaluate the expression:

[tex]\log _{6}(36)[/tex]

36 can be written as 6².

       [tex]=\log _{6}\left(6^{2}\right)[/tex]

Using log rule: [tex]\log _{a}\left(x^{b}\right)=b \cdot \log _{a}(x)[/tex]

       [tex]=2 \log _{6}(6)[/tex]

Using log rule: [tex]\log _{a}(a)=1[/tex] so that [tex]\log _{6}(6)=1[/tex]

       = 2(1)

       = 2

[tex]\log _{6}(36)=2[/tex]

Hence the value of [tex]\log _{6}(36)[/tex] is 2.

Final answer:

To find log₆ 36, we determine the exponent that 6 must be raised to to get 36. As 6 squared equals 36, the value of log base 6 of 36 is 2.

Explanation:

The question asks us to evaluate the logarithm of 36 with a base of 6, or, in mathematical terms, log base 6 of 36. We can solve this by recalling the definition of a logarithm, which is the power to which a base number must be raised to yield a given number. Since 6 squared is equal to 36 (6² = 36), the logarithm of 36 with a base of 6 is equal to 2.

Step-by-step explanation:

Answer:

56 legs

Step-by-step explanation:

Because each spider has 8 legs and there are 7 spiders in all, you must find the product of 8x7. This is just a simple multiplication problem, so 8 multiplied by 7 is 56.

The width of the rectangle can be represented by the expression (121-x^2) / (11-x).

To find the width of the rectangle, we need to divide the area of the rectangle by its length. The area of the rectangle is given by the expression 121-x^2, and the length is given by 11-x. So, we can represent the width as:

Width = (Area / Length) = (121-x^2) / (11-x)

Let a, b, and c be the length of 3 corresponding sides of the triangle. The following inequality must always be true since they form a triangle :

[tex]a+b>c[/tex]

(This inequality says that the sum of two sides must always be greater than the other side)

Let's use this inequality for x, 1.3, and 4.1

[tex]x+1.3>4.1[/tex]

(The reason why 1.3 is on the left side is because it is the smaller side)

Subtract both sides by 1.3

[tex]x>2.8[/tex]

x must always be greater than 2.8. Now, let's see what value x must be always less than.

[tex]1.3+4.1>x[/tex]

[tex]5.4>x[/tex]

x must be always less than 5.4. Let's combine both statements for x and we get:

[tex]2.8<x<5.4[/tex]

These are the only values of x that will make it possible for these sides to form a proper triangle.

Answer:

The answer is D: 5

Step-by-step explanation:

5 x 5 = 25 - 4 = 21 and 3 x 5 = 15 + 6 = 21

Answer: 5

Step-by-step explanation: Here, we want to determine which number can be replaced for the variable in this problem so the statement holds true.

5 would be the only number in this set that can work. Let's test it out.

We can do this by simply plugging in 5 for x. If the statement holds true when 5 is plugged in for x, then 5 is a solution.

Plugging in 5 for x, we have 5(5) - 4 = 3(5) + 6.

Simplifying, we have 25 - 4 = 15 + 6 or 21 = 21 which is a true statement.

So 5 is a solution.

Answer:

Step-by-step explanation:

I don't have a picture so I'll visually describe it. You start at the point (0,9) because 9 is the y intercept. Now that you have your first point, to get the next point, move up one and 2 to the right. Now, you're at the point (2,10). Continue going up one and 2 to the right until you get to the end of the graph. Then, go back to the point (0,9). This time, go the opposite way. Go one down, and two to the left. Now, you should be at the point (-2,8). Continue going down one, two left until once again, you run out of room on the graph. Then, use a ruler or freehand draw a line connecting your points. Add arrows on the ends on the line. Hope this helped!

Answer:

The total area of the field is 7378.8 square meters.

The total area of the field is 8825.0448 square yards.

Step-by-step explanation:

Given : A soccer field (football pitch) has a length of 103.2 m and a width of 71.5 m.

To find : The total area of the field in square meters (m²) and convert this measurement to square yards (yd²) ?

Solution :

The length l=103.2 m

The width w=71.5 m

The area of the field is [tex]A=l\times w[/tex]

[tex]A=103.2\times 71.5[/tex]

[tex]A=7378.8\ m^2[/tex]

The total area of the field is 7378.8 square meters.

We know that,

1 m²= 1.196 yd²

[tex]7378.8\ m^2=7378.8\times 1.196\ yd^2[/tex]

[tex]7378.8\ m^2=8825.0448\ yd^2[/tex]

The total area of the field is 8825.0448 square yards.

The area of the soccer field is 7378.8 m^2 and 8822.6 square yards.

The area of a rectangle (which is the shape of a soccer field) can be found by multiplying the length and the width. So, the area of the soccer field in square meters is 103.2 m (length) times 71.5 m (width), which equals 7378.8 m2.

To convert this area to square yards, you should know that 1 square meter is approximately equal to 1.19599 square yards. So, multiply our previous answer with this value. The area of the soccer field will be 7378.8 m2 times 1.19599 to get 8822.6 yd2.

Step-by-step explanation:

Answer:

126 in.^2

Step-by-step explanation:

The hexagon is divided into 6 congruent triangles. The area of the hexagon is 6 times the area of one of the triangles.

Now think of each triangle.

The side of the hexagon is the base of the triangle. The side of the hexagon has length 7 inches, so the base of the triangle has length 7 inches.

The height of the triangle is approximately 6 inches.

area of triangle = base * height/2

area of hexagon = 6 * area of triangle

area of hexagon = 6 * base * height/2

area of hexagon = 3 * base * height

area of hexagon = 3 * 7 in. * 6 in.

area of hexagon = 126 in.^2

Answer:68

Step-by-step explanation:

Area of triangle=1/2×base×height

1632=1/2×48×h

1632×2=48×h

3264=48×h

3264/48=h

68=h

Final answer:

To find the height of a triangle with an area of 1,632 square inches and a base of 48 inches, we use the formula A = (base × height) / 2. Solving for height gives us a result of 68 inches.

Explanation:

To calculate the height of a triangle when its area and base length are known, we use the formula for the area of a triangle: A = (base × height) / 2. Given that the area of the triangular banner is 1,632 square inches and the base length is 48 inches, we can set up the equation:

1,632 = (48 × height) / 2

Multiplying both sides of the equation by 2 to get rid of the denominator:

3,264 = 48 × height

Next, divide both sides by 48 to isolate the height:

height = 3,264 / 48

height = 68 inches

Therefore, the height of the triangular banner is 68 inches.

so the hours are the y-axis and you can label them 2,4,6,8 because skip counting by twos are probably the easiest! so for the first question, you would line a dot up on top of 1 and go up and you see 2 and 4 right, cuz you just labeled it... do go between 2 and 4 which is 3 and place the dot there...

and keep doing the same things with other ones too...

y = 75

Solution:

In a straight line, sum of the adjacent angles = 180°

80° + m∠DGF = 180°

Subtract 80° from both sides of the equation.

m∠DGF = 100°

Sum of all the interior angles in a quadrilateral = 360°

m∠DGF + m∠GFE + m∠FED + m∠EDG = 360°

100° + 120° + 65° + y° = 360°

285° + y° = 360°

Subtract 285° from both sides, we get

y° = 75°

Hence the value of y is 75.
