Answer:

6.5 cm

Step-by-step explanation:

From Pythagoras theorem

C^2= a^2 + b^2

Where a, b are the sides of the triangle

C= hypotenus sides of the triangle

two sides are given as 1.6 cm and 6.3cm respectively.

C^2= 1.6^2 + 6.3^2

C^2= 2.56 + 39.69

C^2 = 42.25

C= √42.25

C=6.5 cm

Hence, the length of the hypotenuse is 6.5 cm

Answer:

  sin(M) = √7/4

  cos(M) = 3/4

  tan(M) = √7/3

Step-by-step explanation:

The mnemonic SOH CAH TOA reminds you of the relationships of interest.

  Sin = Opposite/Hypotenuse

  sin(M) = (2√7)/8 = √7/4

  Cos = Adjacent/Hypotenuse

  cos(M) = 6/8 = 3/4

  Tan = Opposite/Adjacent

  tan(M) = (2√7)/6 = √7/3

Answer:

172

Step-by-step explanation:

200 x 0.86 = 172

172 cupcakes sold were of mocha flavoured.

Percentage is defined as a given part or amount in every hundred. It is a fraction with 100 as the denominator and is represented by the symbol "%".

Given that, a bakery sold a total of 200 cupcakes in a day, and 86% of them were mocha flavoured.

Let the number of mocha cupcakes sold are x,

Therefore, 86% of 200 = x

x = 200*86/100

x = 2*86

x = 172

Hence, the number of mocha cupcakes sold were 172.

The surface area of a rectangular prism will be 164 square centimeters.

Let the prism with a length of L, a width of W, and a height of H. Then the surface area of the prism is given as

SA = 2(LW + WH + HL)

The dimension of the rectangular prism with a length of 3 cm, a width of 10 cm, and a height of 4 cm. Then the surface area of the rectangular prism is calculated as,

SA = 2(3 x 10 + 10 x 4 + 4 x 3)

Simplify the equation, then we have

SA = 2(30 + 40 + 12)

SA = 2 x 82

SA = 164 square cm

The surface area of a rectangular prism will be 164 square centimeters.

Answer:

(i) The axis of symmetry is [tex]x = -4[/tex].

(ii) The axis of symmetry is [tex]x = 4[/tex].

(iii) The axis of symmetry is [tex]x = 1[/tex].

Step-by-step explanation:

We proceed to explain how we determine the expression for the axis of symmetry for each case:

(i) [tex]f(x) = 3\cdot (x+4)^{2}+1[/tex]

The expression depicts a vertical parabola, meaning that axis of symmetry is vertical, that is, a function of the form [tex]x = a,\,\forall\,a\in \mathbb{R}[/tex]. This line passes through the vertex of the parabola. The component [tex]x+4[/tex] contains the information of the horizontal component of the vertex, where the axis passes through. Therefore, the axis of symmetry is [tex]x = -4[/tex].

(ii) [tex]f(x) = 2\cdot x^{2} -16\cdot x +15[/tex]

At first we complete the square and factor the perfect square trinomial:

[tex]f(x) = 2\cdot \left(x^{2}-8\cdot x +\frac{15}{2} \right)[/tex]

[tex]f(x) = 2\cdot \left[(x^{2}-8\cdot x +16) +\frac{15}{2}-16 \right][/tex]

[tex]f(x) = 2\cdot (x-4)^{2}-17[/tex]

By applying the approach used in (i), we find that the axis of symmetry is [tex]x = 4[/tex].

(iii) First, we locate the vertex of the parabola, which is (1,-3). The first component of the ordered pair contains all the needed information to determine the equation of the axis of symmetry, which is [tex]x = 1[/tex].

Answer:

3 3/4 inches = 562.5 miles

Step-by-step explanation:

Given that,

1/2 inch = 75 miles

It means,

1 inch = (75×2) miles

= 150 miles

3 3/4 inches= 15/4 inches

So,

[tex]\dfrac{15}{4}\ \text{inches}=\dfrac{15}{4}\times 150\\\\=562.5\ \text{miles}[/tex]

Hence, 3 3/4 inches is equal to 562.5 miles.

The answer of the given question based on the Graph is , option (b) There is one x-value that satisfies the equation 4x+4=2(2x-1).

An equation is mathematical statement that asserts that the two expressions are equal. It typically contains variables, constants, and mathematical operations such as addition, subtraction, multiplication, and division. Equations are often used to solve problems or find the values of variables that make the equation true.

The equation 4x + 4 = 2(2x - 1) can be simplified as follows:

4x + 4 = 4x - 2

4 = -2

This equation is not true, which means there are no values of x that satisfy the equation. Therefore, statement (b) There is one x-value that satisfies  equation 4x+4=2(2x-1) is not true.

Statement (a) "There are no x-values that satisfy the equation 4x+4=2(2x-1)" is true.

Statement (c) "The lines of y = 4x + 4 and y = 2(2x-1) do not intersect" is also true, as we can see from the graph.

Statement (d) "The equation 4x+4=2(2x-1) has no solutions" is true, as we have already shown that there are no values of x that satisfy the equation.

Therefore, the answer is (b) There is one x-value that satisfies the equation 4x+4=2(2x-1).

Answer:

Answer: A. (10,-8)

Step-by-step explanation:

Y=10

X=-8

Step1. Replace the equation with the given numbers

Step2. 10=-1/4•-8+8

Step3. -1/4=-0.25

Step4. -0.25•8=2

Step5. 2+8=10

And that is how you get A.(10,-8)✌

The solution to the equation y=-1/4x+8 is (4, 8).

Thus, option (B) is correct.

Given Equation:  y=-1/4x+8

A. (10, -8)

Substitute x = 10 and y = -8 into the equation:

-8 = (-1/4)(10) + 8

-8 = -2.5 + 8

-8 ≠ 5.5

B. (4, 8)

Substitute x = 4 and y = 8 into the equation:

8 = (-1/4)(4) + 8

8 = -1 + 8

8 = 8

C. (-4, 9)

Substitute x = -4 and y = 9 into the equation:

9 = (-1/4)(-4) + 8

9 = 1 + 8

9 = 9

D. (-8, -10)

Substitute x = -8 and y = -10 into the equation:

-10 = (-1/4)(-8) + 8

-10 = 2 + 8

-10 ≠ 10

Now, (4, 8) is the only point that satisfies the equation y = -1/4x + 8.

Therefore, (4, 8) is the solution to the equation.

Thus, option (B) is correct.
