Answer:

for \: a \: right \: angled \: triangle \\ (3x + 38) + (4x + 3) + 90 = 180 \\ (4 + 3)x = 180 - (90 + 38 + 3) \\ 7x = 49 \\ x = 7 \\  \\  mZD=(3x + 38) \\  = (3 \times 7) + 38\\ mZD = 59° \\  \\ mZF=(4x+3)° \\  = (4 \times 7) + 3 \\ mZF = 31°

Find the zeros of each function by using a graph and a table f(x)=x^2+3x-18.
Debora [2.8K]

1) Finding the zeros of this function f(x) =x² +3x -18

f(x) = x²+3x-18 <em>Factoring this equation, and rewriting it</em>

<em />

<em>Which two numbers whose sum is equal to 3 and their product is equal to 18?</em>

<em>6 -3 = 3 and 6 *-3 = -18</em>

<em />

<em>So we can rewrite as (x +6) (x-3)</em>

<em> </em>

(x+6)(x-3)=0 <em>Applying the Zero product rule, to find the roots</em>

x+6=0,

x=-6

x-3=0,

x=3

S={3,-6}

2) Setting a table, plugging in the values of x into the factored form: (x-6)(x-3)

x | y |

1 | -14 (1 +6)(1-3) =-14

2 | -8 (2 +6)(2-3) =-8

3 | 0

4 | 10

-5 | -8

-6 | 0

3) Plotting the function:

What is the volume of a rectangular prism with the dimensions: base 7 2 cm, height 3 2 cm, and length 9 2 cm? A) 189 2 cm3 B) 18
motikmotik

Answer: D)  \dfrac{189}{8}\ cm^3

Step-by-step explanation:

The volume of a rectangular prism is given by :_

\text{Volume}=\text{length*width*height}

Given: Length of the rectangular prism = \dfrac{9}{2}\ cm

Width =  \dfrac{7}{2}\ cm

Height =  \dfrac{3{2}\ cm

Then, the volume of a rectangular prism will be :-

\text{Volume}\dfrac{9}{2}\times\dfrac{7}{2}\times\dfrac{3}{2}\\\\\Rightarrow\text{Volume}=\dfrac{189}{8}\ cm^3

X2+11x-26=0<br> X2 - 25 = 0
Oksanka [162]
X² + 11x - 26 = 0
x² - 25 = 0

(x + 13)(x - 2) = 0
(x + 5)(x - 5) = 0

x = -13
x = 2
x = -5
x = 5
