Answer:

f(5)=11

Step-by-step explanation:

f(x)=4x-9

f(5)=4(5)-9

f(5)=20-9

f(5)=11

Answer:

f(5) = 11

Step-by-step explanation:

F(x) = 4x - 9 for f(5)

x gets replaced with 5

f(5) = 4(5) - 9

f(5) = 20 - 9

f(5) = 11

AC = 11.4

Step-by-step explanation:

6/sin 23 = AC/sin 132

6 sin 132/sin 23 = AC

AC = 11.4

Answer:

90°

Step-by-step explanation:

There is no work. We know the right angle in the triangle and  the x are supplementary. Meaning, they add up to 180 degrees.  Therefore, 180-90 = 90. Think of it as a full triangle. If the 40 at the top was not half, but a full triangle, the 40 at the top would become 80. The 50 in the bottom left would mean there would be a 50 in the bottom right when you mirror the triangle. Therefore, you also need x to be 90 to make it a right triangle.

Answer:

ΔABC≅ΔDEC by AAS

Step-by-step explanation:

You can use the AAS method of congruency.

Since you already have <BAC and <EDC congruent to eachother, and sides BC and EC congruent to each other, you only need that one remaining angle in between. <ACB can be proven congruent to <DCE by the Vertical Angles Theorem, and that gives you the AAS you need to prove that these two triangles are congruent

17Answer:

Step-by-step explanation:

The area of ΔNOP is approximately 2.11 square centimeters, rounded to the nearest 10th of a square centimeter.

Suppose the vertices of the considered triangle ABC are on A(A_x,A_y), B(B_x,B_y), C(C_x,C_y), then, the area of the triangle is given by:

[tex]Area = \dfrac{|A_x(B_y-C_y) + B_x(C_y-A_y) + C_x(A_y-B_y)|}{2}[/tex]

We are given that;

Side P=2.5cm

Side N=2.3cm

Angle O=71

Now, to find the area of a triangle, we can use the formula:

A = (1/2) * base * height

where base and height are two sides of the triangle that form a right angle, or any two sides of the triangle if we know the included angle between them.

In this case, we are given the lengths of two sides, p and n, and the measure of one angle, ∠O. To find the area, we need to first find the length of the third side, OP, using the Law of Cosines:

OP² = p² + n² - 2pn cos(∠O)

OP² = 2.5² + 2.3² - 2(2.5)(2.3) cos(71°)

OP² = 4.2694

OP ≈ 2.067 cm

Now we can use the formula for the area of a triangle:

A = (1/2) * OP * n * sin(∠O)

A = (1/2) * 2.067 * 2.3 * sin(71°)

A ≈ 2.11 cm²

Therefore, the area of triangle NOP will be  2.11 square centimeter.

All the beans are equally likely to be chosen, so the bottom (denominator) of the fraction is 12 (there are 12 beans in the box).

The numerator is 5 because that's the number of red beans in the box.

Step-by-step explanation:

Answer:

(-6, 8)

Step-by-step explanation:

Since the radius is 10 units and the center is on the origin of the circle, the distance from the origin to the point (-6, y) must be 10.

We can use the distance formula given by:

[tex]d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2[/tex]

We will let the point (-6, y) be (x₂, y₂) and the origin point (0, 0) be (x₁, y₁). The distance is 10. Substitute:

[tex]10=\sqrt{((-6)-(0))^2+((y)-(0))^2}[/tex]

Simplify:

[tex]10=\sqrt{(-6)^2+(y)^2}[/tex]

Square both sides and simplify:

[tex]100=36+y^2[/tex]

Solve for y:

[tex]y^2=64[/tex]

Take the square root of both sides:

[tex]y=\pm\sqrt{64}=\pm 8[/tex]

Since our point is in QII, y must be positive. Hence, we will use the positive case. So, y = 8.

Our point is (-6, 8).

Answer:

Step-by-step explanation:

Answer:

The price of T-shirts before the sale = 42 euros

The price of scarves before the sale = -77/2 euros

Step-by-step explanation:

The cost of the items Zina buys from the store initially are;

Two scarves and three T-shirts for 49 euros

The reduction in the price of scarves a week later during sales = 1.5 euros

The reduction in the price of T-shirts a week later during sales = 2 euros

The items Zina bought for 40 euros at the reduced price of the sales opportunity are;

Four scarves and five T-shirts for 40 euros

Let 'x' represent the initial price of a scarf and let 'y' represent the initial price of a T-shirt, we  have;

2·x + 3·y = 49...(1)

4·(x - 1.5) + 5·(y - 2) = 40...(2)

Expanding equation (2) gives;

4·x - 6 + 5·y - 10 = 40

4·x + 5·y = 40 + 6 + 10 = 56

∴ 4·x + 5·y = 56...(3)

By multiplying equation (1) by 2 and subtracting the result from equation (3), we get;

4·x + 5·y - 2 × (2·x + 3·y) = 56 - 2 × 49 = -63

-y = -42

y = 42

The price of T-shirts before the sale = 42 euros

x = (49 - 3 × 42)/2 = -77/2

x = -77/2

The price of scarves before the sale = -77/2 euros

(However, if the had bought the 4 scarves and 5 T-shirts during sales at 70 euros, we get;

The price of T-shirts before the sale = 12 euros

The price of scarves before the sale = 6.5 euros.

The allowable total price for the reduced 4 scarves and 5 T-shirts is between 66 and about 82 for both initial prices to be +ve)

Answer:

x=-4

Step-by-step explanation:

The axis of symmetry is the x-value where the two “curves” of the parabola start at. For this parabola, the curves start at x=-4 and extend outward. So, the axis of symmetry is x=-4.

Answer:

x = -4

Step-by-step explanation:

The axis of symmetry is a vertical line thru the vertex.  The vertex is (-4, 2).

So, the line of symmetry is x = -4
